A vibration of frequency 5 hz sends a wave of wavelength 0.8 meters down a rope. what is the speed of sound?

Given:

f ( frequency ) = 5 Hz

λ ( wavelength ) = 0.8 meters

s ( speed ) = ? unknown

Formula:

s = λ / f

Solution:

we can use the formula ( s = λ × f ) in order to solve the problem:

s = λ / f  

 = 0.8 m × 5 Hz  

 = 4 m/s

Answer:

The speed of the radio wave is  4 m/s
