Yandel Osborne · Answer 1

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
