Describe the relationship between wavelength and frequency.

The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength. A hertz has units of 1/second. Wavelength and frequency of a wave are related by the equation Velocity = Wavelength x Frequency, where the velocity is the speed of a wave peak as it passes a stationary point. For all electromagnetic waves (in a vacuum) the velocity = c, the speed of light.
