Question

I'm in hurry please.

Radio waves are readily diffracted around buildings whereas light waves are negligibly diffracted around buildings. This is because radio waves:

are plane polarized

have much longer wavelengths than light waves

have much shorter wavelengths than light waves

are nearly monochromatic (single frequency)

are amplitude modulated (AM)

are plane polarized

have much longer wavelengths than light waves

have much shorter wavelengths than light waves

are nearly monochromatic (single frequency)

are amplitude modulated (AM)

Explanation / Answer

if wavelength of wave is of order of slit width.

then Diffraction will be observed.

wavelength of radio wave is in meters.

thats why radio are diffracted around building.

but light wave have wavelengths in nanometer.

Ans(b) much longer wavelength than light waves.
