Question

Two mechanical waves are traveling through the same medium, and Wave X has an amplitude of 2 cm and Wave Y has an amplitude of 3 cm.How do the two waves' speeds compare?A.   Wave X has a greater speed. B.   Wave Y has a greater speed. C.   Wave X and Wave Y share the same speed. D.   The speed of the waves is impossible to compare without more data.Part 2Which best explains the correct answer to Part 1?A.   The speed of a wave is always constant. B.   The speed of a wave is directly proportional to its amplitude.C.   The speed of a wave is determined by its wavelength and frequency.D.   The speed of a wave is affected by the properties of the medium it is traveling through, not amplitude.

Answer 1

1. C. Wave X and Wave Y share the same speed.

2. D. The speed of a wave is affected by the properties of the medium it is traveling through, not amplitude.

Explanation:

The amplitude of a wave does not affect the speed at which the wave travels. Both wave A and wave B travel at the same speed. The speed of a wave is only altered by alterations in the properties of the medium through which it travels.

Therefore, in the first art the correct answer is C. Wave X and Wave Y share the same speed.

If the medium is uniform (does not change), the speed of the wave will be constant.

Therefore, the correct answer is: D. The speed of a wave is affected by the properties of the medium it is traveling through, not amplitude.
