Which describes light as it passes from air into glass?

What happens to the speed of light if the index of refraction increases?

If two waves traveling in the same direction overlap and thus interfere, which best describes the interference if the waves have a phase difference of 1.5 wavelengths?

In Young’s double-slit interference experiment, if the rays that reach point P on the viewing screen have a path length difference of 0.50 wavelengths, which describes the interference at P?

Solution

(1).The wavelength decreases but the frequency remains the same.

(2). if the index of refraction increases then the speed of light in that medium decreases.

(3).fully destructive interference

(4).It is the first dark fringe to either side of the central bright fringe
