In free space, an electromagnetic wave of 3 GHz of 3 GHz frequency strikes over the edge of an object of size $\frac{\lambda}{100}$ , where $\lambda$ is the wavelength of the wave in free space. The phenomenon, which happens there will be:
Select the correct option:
A
Reflection
B
Refraction
C
Diffraction
D
Scattering
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
$\frac{a}{\lambda}=\frac{1}{100}$
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.
