Light has shorter wavelength than radio.
Explanation:
Light is an electromagnetic wave. In it, the electric and magnetic field oscillate in phase forming a progressive wave.
The distance between two crests of the oscillating electric field will give you the wavelength while the number of complete oscillations of the electric field in one second will be the frequency.
)
The wavelength of light (order of hundred of nanometers) is shorter than radio wavelength (of the order of meters).
