Wavelength and frequency of light are closely related. 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.
Amplitude is the height of a wave which is the brightness of a light or loudness of a sound. So Frequency and Amplitude though are part of a wave are not dependent on each other. Their is no relation between frequency and amplitude.
