What is the index of refraction of the substance

Reference no: EM13662355

A laser beam is traveling through an unknown substance. When it encounters a boundary by air, the angle of reflection is22.0° and the angle of refraction is 41.0°.

1) What is the index of refraction of the substance?

2) What is the speed of light in the substance?

3) At what minimum angle of incidence would the light be totally internally reflected?
