The speed of light in a prticular ype of glass is 1.68x10^8 m/s. What is the index of refraction of the glass? I don't understand if how to solve this problem. Do you put an index of refraction of glass that you know or are you solveing for glass that you don't know? index=...

Light of wavelength 700 nm is incident on the face of a fused quartz prism at an angle of 75 degrees (w/ respect to the normal to the surface). The apex angle of the prism is 60 degrees. Use the value of n=1.46 and calculate the angle (a) of refraction at the surface, (b) of ...

Cherenkov radiation is light emitted by a particle moving through a medium with a speed greater than the speed of light in the medium. (Note: The speed of the particle is not greater than the speed of light in a vacuum.) Consider a beam of electrons passing through water with ...

If the speed of light through material Z is 2.5×108 m/s, what is this material’s index of refraction? The speed of light in a vacuum is 3 × 108 m/s.

We did a refraction lab and we used a semi circular prism and through it we shot a light beam in order to find the angle of refraction. Why is it that we used a semi circle and not perhaps a per circle or some other kind of prism? Thanks :)
