What Wave Diffracts the Most When Encountering an Obstacle?

1 Expert Answer
Among electromagnetic waves, radio waves are diffracted more than visible light, since radio waves have wavelengths of a few meters or kilometers, while light has wavelengths of a few hundred nanometers.

Which wave Diffracts the most?

In short, the angle of diffraction is directly proportional to the size of the wavelength. Hence red light (long wavelength) diffracts more than blue light (short wavelength). And radio waves (really long wavelength) diffract more than X-rays (really short wavelengths).

What happens when waves encounter an obstacle?

A wave encountering a small obstacle tends to bend around the obstacle. This bending of the wavefront is called diffraction. When a wave encounters a barrier with an aperture, which is much smaller than the wavelength, the wave bends and spreads out as a spherical circular wave.
