A is the crest and C is the trough, the value of B is called amplitude, and D is known as wavelength.
What is wavelength?
The distance between two successive troughs or crests is known as the wavelength. The peak of the wave is the highest point, while the trough is the lowest.
The wavelength is also defined as the distance between two locations in a wave that have the same oscillation phase.
A is the highest point of the curve is known as the crest and C is the lowest point of the curve is known as a trough.
B is the amplitude of the curve. And D is the wavelength of the curve.
