Waves Quiz 1

What is the period of the wave given by y = 0.003 sin ($\frac{\pi}{0.08} t + \frac{\pi}{8}x$) (in SI units) ?

The equation of a progressive wave is y = 7 sin(4t – 0.02x), where x and y are in centimetre and time t in second. The maximum velocity of a particle is

When a longitudinal wave is incident at the boundary of a denser medium, then

A transverse wave travelling in a denser medium is reflected from a rarer medium. Then,

Two simple harmonic waves of the same amplitude and frequency, but 90° out of phase, pass through the same region in a medium. The resultant wave has

At a given instant two vibrating particles in the same loop of a stationary wave have

Two vibrating particles in the adjacent loops of a stationary wave have ….. at a given instant.

A stretched string, 2 m long, vibrates in its third overtone. The distance between consecutive nodes is

A stretched string of length $l$ vibrates in the third overtone. The wavelength of stationary wave formed is

A stretched string tied between two rigid supports vibrates with a frequency double the fundamental frequency. The point midway between the supports is
