The wavelength of light is always inversely proportional to its frequency, so if one increases, then the other decreases.
Wavelength represents the distance between two successive crests or troughs of a wave
Frequency is the number of oscillations or cycles per unit time.
Wavelength and frequency are related by the equation: speed of light = wavelength x frequency, where the speed of light is approximately 299,792,458 meters per second in a vacuum.
Amplitude refers to the maximum displacement of a wave from its equilibrium position.
Amplitude is a measure of the wave’s intensity or energy.
In the context of light waves, amplitude determines the brightness or intensity of the light.
