1 Medium

1 of 1

Understanding +4 | -1

Assertion: Standing wave does not transfer energy in the medium.
Reason: Every particle vibrates with its own energy and it does not share its energy with any other Particle.

View answer and explanation

Correct option: A

If both Assertion & reason are True & the Reason is a correct explanation of the Assertion

Option A (If both Assertion & reason are True & the Reason is a correct explanation of the Assertion) is correct because standing waves do not transfer energy, and this is because each particle vibrates with its own energy without sharing it.

The source of sound generating a frequency of

3\,\,kHz

reaches an observer with a speed of

0.5

times, the velocity of sound in air. The frequency heard by the observer is A source of sound emits waves with frequency

V\mathrm{ }m/sec

. Two observers move away from this source in opposite directions each with a speed

0.2\,\,V

relative to the source. The ratio of frequencies heard by the two observers will be Assertion: The wave function of a pulse is given by

y = \frac{3}{{{{\left( {2x + 3t} \right)}^2} + 4}},

it propagates in
