Question

A wave of frequency 100 Hz travels between X and Y, a distance of 600 m in 2 sec. How many
wavelength are there in distance XY –
(a) 3 (b) 300
(c) 180 (d) 2000

Answer 1

Step-by-step explanation:

Speed of sound = Distance covered/Time taken

= 600 m/2 sec = 300 m/sec

frequency = 100 Hz

wavelength = ?

speed of sound = frequency × wavelength

wavelength = speed/frequency

= 300 m/sec

100 cycles/sec

= 3 m (a)
