A wave moving with a speed of 20 m/s has a frequency of 10 Hz. What is the wavelength of the wave?A. 0.5 mB. 30 mC. 200 mD. 2 m

Answer :

In order to calculate the wavelength of the wave, use the following formula:

[tex]v=\lambda f[/tex]

where:

λ: wavelength = ?

v: speed of the wave = 20 m/s

f: frequency = 10 Hz

solve the equation above for λ and replace the values of v and f:

[tex]\lambda=\frac{v}{f}=\frac{20m\text{ /s}}{10Hz}=2m[/tex]

Hence, the wavelength of the wave is 2 m
