A hill stands between a radio transmitter and a house, as shown. [Figure showing a hill between a radio transmitter and a house] The radio transmitter cannot be seen from the house, but radio waves from the transmitter are received at the house. Why is this?
AThe wavelength of light is longer than the wavelength of radio waves so there is more diffraction of light over the hill.
BThe wavelength of light is shorter than the wavelength of radio waves so there is more diffraction of light over the hill.
CThe wavelength of radio waves is longer than the wavelength of light so there is more diffraction of radio waves over the hill.
DThe wavelength of radio waves is shorter than the wavelength of light so there is more diffraction of radio waves over the hill.
