If the lengths of the first and second resonating air columns are 16.5 cm and 51.5 cm with tuning fork of frequency 512 Hz. Calculate the velocity of sound in air

View answer and explanation

Correct option: C

358.4 m/s

Option C (358.4 m/s) is correct because the velocity of sound is calculated using the difference between the lengths of resonating air columns and the frequency of the tuning fork.

. 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

Reason: The given wave function is of the form

y = f(kx +\omega t),

which represent a wave travelling in negative
