Radio wave diffract around building although light waves do not. The reason is that radio waves

A

travel with speed larger than c

B

have much larger wavelength than light

C

are not electromagnetic waves

D

None of these.

Text Solution

Verified by Experts

The correct Answer is:
B
The wavelength of radiowaves being much larger than light, has a size comparable to those of buildings, hence diffract from them.
