Compare to a low wavelength sound wave, a high wavelength sound wave Select all that apply Group of answer choices travels slowe
viktelen [127]

Answer:

B. has a smaller frequency

C. travels at the same speed  

Explanation:

The wording of the question is a bit confusing, it should be short/long for wavelength and low/high for frequency. I assume low wavelength mean short wavelength.

All sound wave travel with the same velocity(343m/s) so wavelength doesn't influence its speed at all. It won't be faster or slower, it will have the same speed.

Velocity is a product of wavelength and frequency. So, a long-wavelength sound wave should have a lower frequency.

The option should be:

A. travels slower -->false

B. has a smaller frequency -->true

C. travels at the same speed  --->true

D. has a higher frequency  --->false

E. travels faster has the same frequency  --->false
