2.How does wavelength differ in high and low frequency waves?

A) Describe wavelength in high frequency waves.

B) Describe wavelength in low frequency waves.

1) The distance between two consecuitive peaks is called the wavelenght, so:

A = wavelenght.

The middle of the wave is called the rest position, so:

D = Rest position.

The distance between a peak and trough is called the wave heigt, so:

C = Wave height.

The distance between the rest position and a peak or a trough, is called the amplitude of the wave:

B = Amplitude.

2) Usually in high frequency waves we have shorter wavelenghts and in low frequency waves whe have larger wavenelgths, this is because the relation between frequency and wavelenght comes from:

velocity = wavelength*frequency.

if the velocity is constant, and we have a increace in the frequency, the wavelenght must decrease (so the velocity remains constant).

The same happens if the frequency decreases, the wavelenght must increase.
