Question

A wave has a frequency of 540 Hz and is traveling at 340 m/s. What is its wavelength?

Answer 1

Answer:

wavelength of wave = 62.69 cm

Explanation:

Given

frequency of wave = 540 Hz = 540 $s^{-1}$

Speed of wave = 340 m$s^{-1}$

wavelength of wave = ?

We know that for all waves, the relationship between wavelength λ, frequency f and speed v is same and given by the equation:

v = fλ

Hence wavelength λ  = v/f

                                   = 340 m$s^{-1}$ / 540 $s^{-1}$

                                   = 0.6296 m

                                    = 62.69 cm
