As light passes from one medium to a medium of a different density
A) it is refracted.
B) it bends at specific angles.
C) it changes wavelengths.
D) both (a) and (b) above.
E) all of these answers.

Quizplus · Accepted Answer

When light passes from one medium to another medium with a different density, it changes direction and speed, which is called refraction. The bending of light at specific angles is also a result of refraction. Therefore, both (a) and (b) above are correct. However, the wavelength of light generally remains the same when it passes from one medium to another, making choice (c) incorrect. Therefore, the correct answer is (D) both (a) and (b) above.
