Hi guys, I am curious to find if there is any invention where the friction between the surface of motorway and cars' tyres are used to create kinetic energy which can be converted into electrical energy to power up the houses and plants around them. Thank you.

How does the claddibg with lower refractive index reduce the light loss from the core? Thank you.

Thank you very much, great mentor!

Thank you indeed but last question: why do we reject the other equations. and also even if I make the initial velocity zero, then I would end up with 2s=at^2, t

s=ut+at^2/2 and s=(u+v)/2 x t there is a lot more

Yes, I understand that but I still do not understand why it is X^2. Can you please explain and thank you.

What is the relationship between the distance y traveled by an object falling freely from rest and the time x the object has been falling? The answer to this question is: y is proportional to x2 Can someone tell me how this answer is correct.

Thank you Chandra

At the start of the chapter the book told me to use this formula to find refractive index: N= Sin(i)/Sin(r) How ever later in the section they showed me to use this formula when three quantities are given : NxSin(i)=NxSin(r) I tried apply the same method to a question, it gave me a wrong...

so where do we apply the rule that the frequency changes when wavelength is changed

Are we not viewing light as wave in this case?

I am quite confused, does this means that the wavelength will bot change as well.

I've learned that when wavelength increase the frequency decreases. But in Refraction, there is a mention about frequency remains same but the wavelength and speed changes. Why does the frequency doesn't change? I thought when when wavelength is short the peaks are closer to each other so...

Sorry, I meant to say even number of nodes

Can someone explain why the phase difference is zero when the there is equal number of nodes between the two vibrating particles. Thank you
