When light waves pass through the lenses of a pair of glasses, the light waves .

a) conduct
b) diffract
c) reflect
d) refract

D) refract

Explanation:

When light waves passes through a pair of glasses, it is refracted by the lenses contained in the glasses.

Refraction occurs when light moves across the interface between two different mediums (in this case, between air and the glass of the lenses): when this occur, the direction and the speed of the light waves change.

The change in speed is determined by the index of refraction of the medium, which is the following:

where c is the speed of light in a vacuum, and v the speed of light in the medium;

the change in direction is determined by Snell's law:

where n1 and n2 are the index of refraction of the two mediums, while are the angles that the light ray forms with normal to the interface in the first and second medium, respectively.
