Will light change direction toward or away from the perpendicular when it goes from:
1) Air to water.
2) Water to glass
3) Glass to air
A. A ray of light originating in air is incident on water(n(water)=1.33) at an angle 60o. It then passes throughthe water, entering glass (n(glass) = 1.5) and finally emergingback into the air again. Compute the angle of emergence.
B. If the wavelength of light used above is 600nm in air,calculate its wavelength in both the water and the glass.
