Thank you sir for such a nice, and interesting class
4:00 disco light on 😊
😅😊
the instrument which we use to measure the magnitude of earthquake is called Richter scale.......thank you sir
The device used to measure magnitutude of earthquake is called Ritcher scale.👍
Thanks bro for telling😊😊😊
What is your phone number😊😊😊
If you are boy then you tell me 😊😊😊
If you are a girl then don't tell me 😊😊😊
Right
Not device it is scale

Ya 😂
the layer after crust is called "MANTLE" not 'MENTAL" plz refer it with book
Richter scale is the scale used to measure the magnitude of an earthquake, that is the amount of energy released during an earthquake
The intensity of an earthquakes is expressed in terms of magnitude on a scale is called the Ritcher scale. Thanks 😀😀😀
👍
thank you sir whatever you teach is so clearly engrained in our brains
this really helps during exams
im watching this a day before exam
so true
it's not that cringe it's me being a sweet flower
Legend
The Richter scale is a way of measuring the strength or magnitude of earthquakes. It was developed by Charles Francis Richter and Beno Gutenberg in 19351. The scale is based on the logarithm of the amplitude of seismic waves recorded by seismographs1. The formula for calculating the Richter magnitude is:
ML=log10A−log10A0(δ)
where
ML is the local magnitude,
A is the maximum amplitude of the seismograph,
A0 is a function of the distance from the epicenter, and
is the epicentral distance of the station1.
The Richter scale is logarithmic, which means that each increase of one unit corresponds to a tenfold increase in the amplitude of the waves. For example, an earthquake of magnitude 5.0 produces waves that are 10 times larger than those of an earthquake of magnitude 4.0. The energy released by an earthquake also increases exponentially with the magnitude. Each increase of 0.2 units corresponds to approximately a doubling of the energy released1.
The Richter scale has no upper or lower limit, but most earthquakes have magnitudes between 0 and 10. Earthquakes with magnitudes greater than 4.5 can be detected by seismographs all over the world1. The effects of earthquakes vary depending on the magnitude, the depth, the location, and the geology of the area. The following table shows some typical effects of earthquakes of different magnitudes near the epicenter2:
Magnitude Effects
Less than 2.0 Microearthquakes, not felt, or felt rarely by sensitive people.
2.0-2.9 Minor, felt slightly by some people, no damage.
3.0-3.9 Often felt by people, but rarely causes damage.
4.0-4.9 Light, noticeable shaking of indoor objects, rattling noises, significant damage unlikely.
5.0-5.9 Moderate, can cause major damage to poorly constructed buildings, slight to moderate damage to well-built structures, felt by most people.
6.0-6.9 Strong, can be destructive in areas up to about 160 km (100 miles) across, damage to a moderate number of well-built structures in populated areas.
7.0-7.9
Very Nice 👍👍
Why are you watching this video you know everything 😂😂
Are kaha se late ho itna gyan
In 19351? What year is this again? 😂
@@shivapatel1116 google baba😂😂
sir how to know that on which object we got which type of charge negetive or positive
By induction 👍🏻
10:00 sir said it took 2000 years to realise after 1752 it means 1752+2000 = 3752 sir is living in future 🤣🤣🤣🤣
yes
IMPORTANT🕵POINT
1. Rain is a form of precipitation.
2. Rain is measured by Rain Gause.
3.pH of Rain generally under 6.
4. Word 'Electricity' comes from the Greek word 'Electron' which means Amber.
5. The process of Rain forming is called the 'Bergenon Process'.
6. Charge is measured in Coulombs (C).
7. PW is best. (IMP.) ❤

The energy or the magnitude of the earthquake is measured on an open ended Richter Scale.
I understood this chapter very well.

Two ways to save ourselves from lightning
1. Stay away from an isolated place.
2. Best way is to crouch down if we're in an open field.

True
Richter scale is used to measure intensity of earthquake.
Richter scale is also used to describe the magnitude of an earthquake.

Yes it's right
The Richter scale is an instument which is used to measure the power of earthquakes
It's not an instrument,it's a scale.
1. Richter Scale is used to measure the scale of absolute 'Magnitude' of an earthquake based on the amount of seismic energy released. 2. Mercalli scale measures the 'Intensity' of an earthquake based on based on the amount of destruction caused.
Richter scale used for measuring the intensity of earthquake.The Richter scale measures the maximum amplitude of seismic waves as they reach seismographs The magnitude is expressed in absolute number, 0-10.The power of an earthquake is expressed in terms of magnitude on a scale called the Richer scale.❤❤❤😊
Super 😊

Tomorrow is my exam
Richter scale is used to check the power of an earthquake is expressed
In the term of a magnitude on a scale called the richter scale
A seismometer is the internal part of the seismograph, which may be a pendulum or a mass mounted on a spring; however, it is often used synonymously with "seismograph". Seismographs are instruments used to record the motion of the ground during an earthquake.
21:40 is very good experience🎉
Richter scale is used to measure the magnitude of earthquakes, although the lecture was amazing sir 👏 🙏
For the measurement of the intensity of the earthquake waves, richter scale is used.
yeah and the record is written on seismograph
@@Kiwi_047 The paper used is known as - 'seismogram'
The study of these waves is -'seismology'
The sciencts who study seismology are known as seismologists

A scale that is used to measure the magnitude of an earthquake is called a Richter Scale.
The first widely-used method, the Richter scale, was developed by Charles F. Richter in 1934. It used a formula based on the amplitude of the largest wave recorded on a specific type of seismometer and the distance between the earthquake and the seismometer.

Thank you sir for explaining this much well now I am really ready for class test once again thankyou sir😊😊😊
39:03. It's building not buiding. 😊
The Richter scale-also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg-Richter scale-is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 paper, where he called it the "magnitude scale.
