Which of the following media allow(s) the transmission of sound waves through them? I. Air II. Liquid III. Solid
Which of the following wave characteristics can be used to distinguish a transverse wave from a longitudinal wave?
A sound note of frequency 250 Hz and a wavelength 1.3 m is produced at a point near a hill. If the echo of the sound is received 1 second later at that point, how far away is the hill from the point?
The period of a wave is 0.02 seconds. Calculate its wavelength if its speed is 330 ms\(^{-1}\)
An alternating voltage with a frequency of 50 Hz has a period of
