Question

In free space, an electromagnetic wave of 3 GHz of 3 GHz frequency strikes over the edge of an object of size λ 100 where 2 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

Correct option is (D) Scattering

\(\frac a{\lambda}=\frac1{100}\)

For reflection size of obstacle must be much larger than wavelength, for diffraction size should be order of wavelength. Since the object is of size λ 100 much smaller than wavelength, so scattering will occur.
