Get started for freeSuppose you have an unknown clear substance immersed in water, and you wish to identify it by finding its index of refraction. You arrange to have a beam of light enter it at an angle of \(45.0^{\circ},\) and you observe the angle of refraction to be \(40.3^{\circ} .\) What is the index of refraction of the substance and its likely identity?
Compare the time it takes for light to travel \(1000 \mathrm{m}\) on the surface of Earth and in outer space.
Will light change direction toward or away from the perpendicular when it goes from air to water? Water to glass? Glass to air?
At what angle is light inside crown glass completely polarized when reflected from water, as in a fish tank?
The angle between the axes of two polarizing filters is \(45.0^{\circ} .\) By how much does the second filter reduce the intensity of the light coming through the first?
