Topic: Electromagnetics
When an electromagnetic wave is incident on an object having surface roughness comparable to the wavelength, then
- A. Specular reflection occurs
- B. Absorption occurs
- C. Diffused scattering occurs
- D. None of the above
Answer: C. Diffused scattering occurs
Explanation: If the surface roughness of an object is comparable to the wavelength of the incident electromagnetic wave, the wave is scattered in multiple directions rather than reflecting perfectly. This phenomenon is known as diffused scattering.
