Bro in that case photoelectric effect shown. The photoelectric effect is the emission of electrons when electromagnetic radiation, such as light, hits a material. Ok?
Hello sir, I have doubt in gravitation of class 9 that we know that acoording to universal law of gravitation : 2nd law , force proportional to 1/d^2 , so in case of sun 's radius is so bigger than the earth but why the gravitational force is not less on Sun why. 🙏🏻🙏🏻🙏🏻 Requestly answer my question ..
According to Newton's third law of motion, if earth and sun are two objects, the both(sun & earth) will experience the same gravitational force. There's only a difference in acceleration. Because the sun has more mass, it's acceleration is less than that of earth.
I don't have word to thanks you ❤❤❤❤❤❤❤❤ love you sirrrrrrrrr
Sir, I have a question that what happens during reflection at the atomic level when electromagnet wave i.e light hits electron?, plz reply
Yes, light transfer anergy in election. So electron pushed in atomic path
I am student of class 7
Light particles jaisa bhi bheave karta h
Or iske particles ko hmm photon kahte h

Sir please make videos like this with some extra deep concept ☺️☺️☺️
Thanks sir for your efforts
👍👍
@@edupoint.secondary sir please make a video on how light interact with matter
Sar why hear you take to 2F1 & 2F2 instead of centre of curvature at 12:36 plzzz reply
@@lakshya__gupta because it is 2 × focal length
Thank you sir. Your teaching technique is soo good .
Happy diwali sir 🤩 ...may the little lamps of diwal, light up your life with enjoyment and a lots of happiness 🙏🏻🤗🤗😊
Most needest topic🎊🤓 ....thnks sir🙏🏻 ..u r always my fav. science teacher 😊🙇🏻♀️
🙏🙏
Nice video sir...........😊😊😊😊😊😊😊
🙏🙏
*Crystal clear.. Explanation..*
thank sir your teaching technic is so good
Sir vo physics m root problem aarhi h sin coss ki value nikalety h tab vo samjavo na kasie karein
First study trigonometry then surely you'll understand.
Sir biology ke chapter padhaiye please
nice explanation
Your explanation is best sir
Because of you only I was able to score full marks in science. Specially in physics and chemistry.
Thank you sir.
Sir decomposition reactions me kya hamesha ek hi reactant hota hai? Agar yes toh sir respiration ek decomposition reaction nahi he kya?
Respiratipn is not a decompostion reaction . In decomposition vreaction breakdown of only one reactant occurs
Yes.Only one reactant and multiple products.
Sir aap mast padhate hai maja aa gaya
Awesome 👍👍👍👍
Best explanation
Sir kya app human eye ke video la lakte ho
Superb sir keep it up sir next topic be sign convention please 🙏🏻🙏🏻
Sure, Mayank.
👍👍
Sir isca bad konsa chapter.
Sir, what is the difference between deviation of light and refraction of light ?
Actually they both nearly same
Deviate means to go closer to normal
And refract means both to go closer and move further from normal
Sir can you please explain why work is a relative quantity not absolute
Thankyou sir
Sir your vice is good
good video
sir Chemistry ka Metals and Non Metals wala chapter nehi mil raha hai
Sir , class 9th science term 1 ke most important questions de dijiye
What a explanation 🫡🫡
Thanks sir for this video

Mass is also more
D^2 means distance between sun and earth not radius of sun or earth
According to Newton's third law of motion, if earth and sun are two objects, the both(sun & earth) will experience the same gravitational force. There's only a difference in acceleration. Because the sun has more mass, it's acceleration is less than that of earth.
We are talking about distance between the centres of two masses not the radius...
What is different between oxygen and oxide
O2 = oxygen
Any element + oxygen = oxide
👍👍
Sir angular deviation ache se explain krdijiye PLZZZZZ
Sir 11th class bio 1st chapter video please 🙏
Sir Hindi bhi bataiye🙏
1
Thnx sir
