Light and radio wavs both are electromagnetic in nature. Radiowaves undergo appericable diffraction around buildings, where as light waves do not. This is because

A

wavelength of radiowavesis very small as comparedto the size of the building

B

wavelengths of radio waves is in the region of 200 to 400 m

C

light waves are transverse where as radiowaves are longitudinal

D

light waves travel faster than radiowaves
