Question

solve the following sample a wavelength of passes over a fixed point in space is 20 compression and 20 refraction passes the point in 0.1 seconds find the frequency and time wave

Answer 1

wavelength = distance between 2 consecutive compression or rarefaction

= 2*50

= 100 cm = 1m

20 waves are produced in 0.2 secs

hence frequency = 20/0.2= 100 Hz

time period = 1/f = 0.01 sec
