determine which statement is ture (T) or false(F).
A. the angle (theta) in snells law is measured between the ray and a line perpendicular to the surface.
B. the speed of light in a material increases as the material index of refraction increases.
c. the ratio of a photons speed to its wavelength has the same value for any index of refraction
d. photons of blue light have a higher energy than protons of red light
e. a photons energy depends on its brightness
Homework Answers
A) True - angle is between ray and normal to the surface
B) False - v = c/n, so speed of light in a material decreases as the material index of refraction n increases.
C) True - because this ratio is frequency and frequency is a source property.
D) True - because blue light has higher frequency.
E) False - brightness just means there are more number of photons

A beam of white light is incident on the surface of a diamond at an angle θa. (Figure 1) Since the index of refraction depends on the light's wavelength, the different colors that comprise white light will spread out as they pass through the diamond. For example, the indices of refraction in diamond are nred=2.410 for red light and nblue=2.450 for blue light. Thus, blue light and red light are refracted at different angles inside the diamond, as shown in...

The Ocrit angle is= 24.09 degrees
A beam of white light is incident on the surface of a diamond at an angle 02. (Figure 1) The index of refraction actually depends on the light's wavelength, so the different colors that comprise white light will spread out as they pass through the diamond (like in a prism). The index of refraction in diamond is nblue = 2.450 for blue light while the indices of refraction for the lower frequency colors are...

water interface (the surface of the lake), it is partly
reflected back into the air and partly refracted
or transmitted into the water. This explains why on the surface of
a lake sometimes you see the reflection of the surrounding
landscape and other times the underwater vegetation.
These effects on light propagation occur because light travels at
different speeds depending on the medium. The index of refraction
