Increasing the wavelength of a wave does not directly affect the amplitude of the wave. The wavelength and amplitude of a wave are two independent properties.

The wavelength of a wave refers to the distance between two consecutive points in the wave that are in phase, such as two adjacent crests or two adjacent troughs. It is typically represented by the Greek letter lambda (λ). In general, if you increase the wavelength of a wave, it means that the distance between consecutive crests or troughs becomes greater.

On the other hand, the amplitude of a wave refers to the maximum displacement or maximum value of the wave from its equilibrium position. It represents the intensity or strength of the wave and is typically denoted by the letter A. The amplitude determines the height or depth of the crests and troughs in a wave.

So, changing the wavelength of a wave does not affect the amplitude. You can have a wave with a long wavelength and a large amplitude or a wave with a short wavelength and a small amplitude. The two properties are independent of each other.
