Amplitude does not affect wavelength. It also does not affect wave speed. Amplitude is the energy of the wave measured from the rest position to the top of the crest.

Does amplitude affect frequency?

What is the relation between the amplitude and the frequency of a wave? The amplitude and the frequency of a wave are independent of each other. The amplitude and the frequency of a wave are equal. The amplitude decreases with an increase in the frequency of a wave.

What affects wavelength of a wave?

Wavelength depends on the medium (for example, vacuum, air, or water) that a wave travels through. ... A sound wave is a variation in air pressure, while in light and other electromagnetic radiation the strength of the electric and the magnetic field vary. Water waves are variations in the height of a body of water.
