This channel is gold

[@wanilsonmiranda3048]

Thank you so much for your explanation, professor! Your video is excellent! Good job. 👏

[@PhysicsMadeEasy]

Thank you for your encouraging words Miranda, it encourages me :-)

[@LECityLECLEC]

I love how you read my mind and put why the sky is blue!

[@surendrakverma555]

Very good information. Thanks 🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏

Sir you are excellent 👍

[@learningisfun889]

Thanks a lot!!

[@PhysicsMadeEasy]

You are welcome. Happy leaning!

[@tribudylestari6995]

May i know which book or journal source you used to say that the color of the sun is actually white? Because im very interested in this discussion and i will make a thesis on this matter

[@PhysicsMadeEasy]

As mentioned in another comment, reflection, confirmed by what I found online when I was scripting the video. You can just google it, you will find tons of information.

Which force acts on an electron which makes it move in a sinusoidal or wave nature

[@PhysicsMadeEasy]

An electron carries a charge. When you place a charge carrier in an electric field, it experiences a force: F = qE, where q is the charge it carries and E is the strength of the field at the point you placed the charge carrier. If the electric field strength oscillates, then charge carriers in that field experience an oscillating force of the same frequency as the oscillation of the field. I explain these things in that video: kzbin.info/www/bejne/npyZZKiLndCNfpY You should check it out.

Question ....electron carying energy dissipate it slowly going through resistor but still have the same current value as before ..... Why this happened .. ..I am not able to understand it please explain it

[@PhysicsMadeEasy]

Hi Ayush, Do not confuse the kinetic energy of the electrons with the electrical potential energy they carry via their charge. Every charge that comes out of a battery will go back in (conservation of charge), so when passing through a resistor, the electrons are going at the same speed all along the circuit. What they lose in the resistor is the electrical potential energy they carry via their charge. This very approximate analogy could help: Imagine a motorway with a toll section (a section of the motorway where you have to give money to drive on it). The cars are the electrons. The drivers of cars are the charges. And the electrical potential energy is the money in the pocket of the drivers. When the car passes through the paying section (a resistor), the drivers lose money (the charges lose energy). But this has no impact on the speed of the cars on the whole motorway: the speed of the cars will be the same, before, during and after the paid section (the current is the same all around the circuit). On the other hand, because the paid section of the motorway is expensive, less drivers will want to ride on the full motorway… And the more expensive it is, the less and less drivers will take motorway. (The current in the full circuit decreases when the resistance increases). I hope this helps!

Sir one question

[@danieldanieldadada]

Why do we never see purple or green in the sky? Why do we skip from blue to yellow?

[@PhysicsMadeEasy]

Hi Daniel, interesting question. The reason is that red transmits better in air (is absorbed less by air) than green, and that, like it is said in the video, blue scatters more than green. Green does arrive from the sun, but is either overruled by blue or red.

[@danieldanieldadada]

@@PhysicsMadeEasy I see two scenarios. Or maybe three. 1. The color is much more absorbed than scattered. We don't see it. Like red at noon. 2. The color is much more scattered than absorbed. We see it. Like blue at noon. 3. Scattering and absorption levels are such that we do not perceive that color. Like green at any time. This is all due to the wavelength of each color and the obstacles we have in the atmosphere. But, at some point, the Earth keeps rotating and at sunset we see red. I believe that's because the scattered component of red is more noticeable due to the angle of the Earth with respect to the sun. Assuming that is correct, why don't we see green at any angle? Maybe the proportions of scattering and absorption remain almost constant with angular changes?

Hello Sir . I HAVE A PREDILECTION FOR YOUR TEACHING METHODS. KINDLY POST A VIDEO ON FORCES. FRICTION

[@PhysicsMadeEasy]

Hi Kelvin, there are some: Check the mechanic playlist! For friction and forces, look at this one: kzbin.info/www/bejne/pKjFoJaFn5Z_f7M Feel free to explore the channel, you might find other things you would like!
