Question

In free space, an electromagnetic wave of 3 GHz frequency strikes over the edge of an object of size $\frac{\lambda}{100}$, where λ is the wavelength of the wave in free space. The phenomenon, which happens there will be

• A. Reflection
• B. Refraction
• C. Diffraction
• D. Scattering

Answer 1

Answer: (D)

Scattering

Answer 2

Since size is of the order of$\frac{\lambda}{100}$, hence scattering will take place.
So, Correct option is (D)
