A wire is stretched between two points, 1 m apart. If the speed of the wave generated on plucking the wire is 200 ms\(^{-1}\), what is the minimum frequency which will resonate with the wire?
Sixty complete waves pass a particular point in 4s. If the distance between three successive troughs of the waves is 15 m, calculate the speed of the waves.
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?
