At 4:39, there is a slight mistake. He knew the frequency, and this allowed him to calculate the speed, which came out as 3x10^8, reinforcing Maxwell’s theory
Watching all of your videos again before my exam ( it's tomorrow) and I just realized I never left a like ?! Imma go back and like very single video you you've uploaded, embrace yourself, ha ha !
has anyone heard of the double slit? it's when you have 3 lines which will leave you 2 slits, throw a particle through the slits on a screen you will have 2 particals on the screen, but if you throw electrons they land in many places, here's an example 1 123 1 123 1, it's true search it up
Can an oscillating quantum particle create "harmonic distortion" like RF waves, to other energy levels? For example, in RF waves, you can observe the harmonics in other frequencies. Can something similar be happening with quantum particles, creating "harmonic particles" in other frequency levels or other fields that the particle is interacting with?
You say at 0:53 that because light can be diffracted it cannot be a particle, but electrons can be diffracted and the Planck's constant shows this. Is it possible that light is a particle with a really, really small mass? I'm pretty bad at physics so I may have misunderstood something.
Wave particle duality means that all particles can exhibit wave-like properties, and all waves can exhibit particle like properties. So light can be particles called photons, but they are massless, not a very small mass
How thick is the probe in an STM? It looks like a few atoms. If so how do they get it that thin and still structurally sound? Further how do they make such accurate adjustments to its height?
Yep, it is a couple atoms thick at the tip. It's a crystal effectively, so it's strong enough. It doesn't need to touch anything of course. They make accurate movements with piezo-electric crystals. If you apply a p.d. across them, they change shape ever so slightly.
@@ScienceShorts Wow metal's taking up metalic structures and piezo-electric crystals what a great answer, thank you! That was actually a question from a class of 15 odd, will share with them. :)
If you would prefer a written description of this you'll be able to find it on my website soon (if you don't mind me suggesting this Science Shorts). If Science Shorts does not want me to send a link he can delete this comment.
Hertz applied a high p.d across the spark gap of his transmitter. As sparks flew across the gap, radio waves propagated outwards from the transmitter. (the power supply you mentioned was connected to the transmitter which was the first spark gap). Remember this experiment was done 20 years after Maxwell showed mathematically the existence of electromagnetic waves. As the waves went past his receiver (the loop with a gap) because radio waves are propagating oscillating magnetic and electric fields, there was a change in flux in the receiver which caused an emf to be induced and a spark to be observed. This showed Hertz that a "changing flux" must have propagated from the transmitter to the receiver. This matched Maxwell's description and prediction of the radio waves perfectly, hence was taken to be experimental evidence for them.
You have the wrong representation of wave-particle duality, nobody has except my unproved theory :) Where to find passionate professional physicists that will want to test it.
Science Shorts if I'll try to explain just that I'm afraid I will look more stupid than I am. To have a chance I have to explain the whole quantum model. Are you curious in the theoretical work of an amateur? (no math LOL, but is testable :p)
What gets me most is the diagram he draws at 2:08. Alexa, add this to my oddly satisfying compilation
this is the perfect summary jut to go over everything before my exam tomorrow

yep you're right.He had the frequency and found the wavelength.
you're literally saving my grades thank you so much

Thanks!
@@fahrenheit2101 grammar nazi liking his own comment lol. You're a chump m8.
Your videos are lifesavers... Thank you for the time and effort you have made for all these!
For aqa spec it states that the probe is negatively charged in comprison to surface and electrons tunnel from the probe to the surface
Hi sir, your turning point videoes are really helpful!
today i realised the profile picture of science shorts was a pair of shorts
ahahahhahaah
46 mins before my final exam 😩😩😩
How did your exam go?
3 years late😭
@@covenantfosu4872 bruh💀
You alive ?
could you do a video on Fizeau's measurement of the speed of light and how to derive the formula please? x
has anyone heard of the double slit? it's when you have 3 lines which will leave you 2 slits, throw a particle through the slits on a screen you will have 2 particals on the screen, but if you throw electrons they land in many places, here's an example
1 123 1 123 1, it's true search it up
Thanks for the video 👍🏼
Isn't Fizzeau's experiment part of this topic too?
Is this stuff on aqa spec? cant remember ever learning it
yeah I was just thinking this as well. first time seeing that formula
It's one of the modules you can choose to take at A2, instead of Engineering, Electronics, Astrophysics or Medical Physics.
@@thesvenvids7708 ah thank you! was stressing about this when Ive already got a whole heap of astrophysics to learn already

have you got videos on polarisation, interference, path difference etc
Go on his stationary waves video,
Your videos are so helpful! Is it possible to do some on Medical Physics?
Ikr. Why doesn't he have any on medical imaging...
@@mustafasiddiqui4161 Cause Medical is for people who want to give up thier life for studying.
sorry but if we know that wave length = h/mv then why do we have electrons and not protons in the microscope.
Gale and Doherty dream of being this guy
30 mins before my exam 😅
Is this relevant to Edexcel Physics?
yes it is.
@@shozabamir3239 but turning points is not a module

i dont understand the hertzs bit. is there somewhere i can read up on it plz. thanks

PlanckTime dude the exam is tomorrow
I know bro, Unfortunately it's not finished:( If there is a certain bit you don't understand I can try and explain on the comments?
How does having sparks in 2 different things mean that a field is involved? Is one connected to a power supply? How close r they?
Hertz applied a high p.d across the spark gap of his transmitter. As sparks flew across the gap, radio waves propagated outwards from the transmitter. (the power supply you mentioned was connected to the transmitter which was the first spark gap).

Cheers ill buy you a beer, its the least i can do?
Thank you!
Is this As physics omg I’ve never learnt this??
This is A2 in the optional topic Turning Points
Tho wave particle duality does turn up in AS too
I need know electron are wave or particle sir. You made 13 minits video so is electron wave or parical ? Pleasexmake it to the point please.
its both at the same time
Lol
Where is the theory proving light as waves?
Diffraction, polarisation.
is this OCR?
You have the wrong representation of wave-particle duality, nobody has except my unproved theory :)
Where to find passionate professional physicists that will want to test it.
Go on then...
Science Shorts are you a professional or a passionate (curious) person?
Science Shorts if I'll try to explain just that I'm afraid I will look more stupid than I am. To have a chance I have to explain the whole quantum model. Are you curious in the theoretical work of an amateur? (no math LOL, but is testable :p)
markmd9 so what happened to your theory
@@Brooomstick Unfortunately he is not capable to do the thinking for himself.
I am super angry at you because I am getting nothing that you are teaching since last video, I was making notes ...... I am regretting now
8:33 - i thought that a smaller de Broglie wavelength means there is greater diffraction?
Not if wavelength is smaller than what it's diffracting around.
