Compared to the wavelength of incident light,diffuse reflection occurs when the size of surface irregularities is
A)smaller.
B)larger.
C)about the same.

Question

Quizplus · Accepted Answer

Diffuse reflection occurs when the surface irregularities are larger than the wavelength of the incident light. This causes the light to scatter in different directions, giving a matte or non-glossy appearance to the surface. If the irregularities are smaller than the wavelength of light, the surface would appear smooth and shiny, and the reflection would be specular (mirror-like). Therefore, the best choice is B, larger.
