Question

1. What is the wave speed of a wave that has a frequency of 100 Hz and a wavelength of 0.30 m?

Answer 1

Answer: The wave speed of the wave is 30 m/s

Explanation:

Wave speed is defined as the product of its wavelength and frequency.

Mathematically,

$\text{Wave speed}=\lambda\times \nu$

where,

$\lambda$ = wavelength of the wave = 0.30 m

$\nu$ = frequency of the wave = 100 Hz = $100s^{-1}$

Putting values in above equation, we get:

$\text{Wave speed}=0.30m\times 100s^{-1}\\\\\text{Wave speed}=30m/s$

Hence, the wave speed of the wave is 30 m/s

Answer 2

Wave speed = frequency x wavelength 
                     =   100 x 0.3
                     =       30 m/s.

Hope this helps!
