1. the amplitude of a wave describes

a. how fast a particle on a wave will move through the medium.
b. how fast a particle will vibrate in a fixed position.
c. how far the particles will move from equilibrium.

1. increasing the amplitude in a transverse wave will cause the wave speed to

a. increase
b. decrease
c. do nothing; will not change

1. wavelength of a wave will increase if . choose all that apply.

a. frequency increases
b. amplitude & speed increase
c. speed increase
d. frequency decreases
e. amplitude decreases
f. speed decreases

Explanation:

1. In a wave, the frequency describes how fast the wave particles move through the medium. Particles in a wave vibrate about a fixed - point (not rotate around a fixed point or move from their normal resting position in the way described in incorrect options).
2. Increasing the frequency in a transverse wave will not change the wave speed. Wave speed in a given medium is determined by the properties of the medium and not by frequency.
3. The amplitude of a wave describes how far the particles on a wave will move from equilibrium. It is a measure of the maximum displacement of the particles.
4. Increasing the amplitude in a transverse wave will cause the wave speed to do nothing; will not change. Wave speed depends on the medium's properties, not amplitude.
5. Wavelength of a wave will decrease if frequency increases (since $v = f\lambda$ and wave - speed $v$ is constant in a given medium, so when $f$ increases, $\lambda$ decreases).

Answer:

1. a. How fast the wave particles move through the medium
2. c. do nothing; will not change
3. a. How far the particles on a wave will move from equilibrium
4. c. do nothing; will not change
5. a. Frequency increases
