Question

The frequency of a sound wave is 50 hz and its wavelength is 4 m. What is the speed of the sound wave?

Answer 1

Answer:

speed = 100m/s

Explanation:

frequency = 50 Hz

wavelength = 4 m

v = frequency×wavelength

v= 50×4=100m/s

Answer 2

Answer:

Explanation:

speed = 100m/s

Explanation:

frequency = 50 Hz

wavelength = 4 m

v = frequency×wavelength

v= 50×4=100m/s
