Question

Whether a target reflects specularly or diffusely (or in between) depends on both the surface roughness of the feature and the wavelength of the incoming radiation.

Answer 1

Answer:

This is True

Explanation:

Wave is a disturbance or the transition of vibrating energy from one point to another. The wavelength of a wave is the distance between the vibrating peak or the crest of the wave. It is the ratio of wave velocity and frequency.

Rough and dull surfaces tend to absorb wave radiation better than shiny and reflective surfaces. The diffusion, reflection and refraction of radiation also depend on the wavelength of the wave or radiation. For example, water absorbs radiation with long wavelengths than waves with short wavelength.
