Question

A sound wave travelling in a medium is represented as shown in figure a) Which letter represents the amplitude of the sound wave ? (b) Which letter represents the wavelength of the wave ? (c) What is the frequency of the source of sound if the vibrating source sound makes 360 oscillations in 2 minutes ? d) Calculate the time period of the source of sound.

Answer 1

Answer:

(a) Letter x: amplitude

(b) Letter y: wavelength

(c) frequency ν =Number of oscillations/time = 360/(2x60) = 3 Hz

(d) Time period t = 1/ν = 1/3 s
