A hill lies between a radio transmitter and a house, as illustrated. The transmitter is not visible from the house, yet radio waves from it are detected at the house. Why does this happen?
- 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.
