Question 96: EM waves

Question

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

Accepted Answer

$$
\frac{\mathrm{a}}{\lambda}=\frac{1}{100}
$$
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 $\frac{\lambda}{100}$, much smaller than wavelength, so scattering will occur.
