to determine the refractive index of a glass prism?

Question

show how the angle of deviation of a ray of light varies with the angle of incidence.

Answer 1

I know the answer is in my basic physics book. I would have to look it up. You should too.

Answer 2

properly purple gentle has a bigger wavelength. So, it has bigger potential and it deviates much less from it is direction while it penetrates a medium which provides predicament in it is direction. evaluate it like a bullet entering into a sack of flour. the better the kinetic potential of the bullet, the extra it penetrates and the lesser the sack is able to provide up the bullet. The exchange in wavelength is obviously proportional yet you notice, if there is 10 p.c. exchange in wavelength, the exchange in wavelength could be extra desirable in purple gentle by way of fact it has an greater wavelength. proportion exchange in blue gentle could be much less. by way of fact of this refractive index of blue gentle is bigger.

Answer 3

That would be Snell's Law, which should indeed be in your textbook.
