Question

Calculate the speed of a wave with a frequency 5.2 Hz and a wavelength of 2.0 meters.

Answer 1

★Question ★

➝Calculate the speed of a wave with a frequency 5.2 Hz and a wavelength of 2.0 meters ?

★ Answer ★

Given :-

➠Frequency =5.2 Hz

➠Wavelength =2.0m.

★To Find★

➝The speed of wave?

★ Solution ★

➠ Speed of wave =Wavelength × Frequency

➠V = λf

➠V=2.0×5.2

➠V=10.4m/s

∴ The speed of wave =10.4m/s

★Some important term in Sound ★

➠ Wavelength :- The minimum distance after which the state of disturbance is repeated in wave motion is called the wavelength of the wave.

➠ Time Period:- The time taken to complete one oscillation of the density of the medium is called the time period of the sound wave.

➠ Frequency :- The number of oscillations of the density of the medium at a place per unit time is called the frequency of the sound wave.

➠ Wave Speed :- The speed with which a disturbance propagate in a medium is called Wave speed.
