Assertion(A): Speed of sound in

\mathrm{O}_2

gas at temperature

T

v

. If temperature is increased to

2 T

, the molecular oxygen breaks into atomic oxygen. Then, speed of sound under these conditions will become

2 v

.

Reason(R): With increase in humidity in air, speed of sound increases.

View answer and explanation

Correct option: B

If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion.

Option B (If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion) is correct because both the assertion and the reason are true statements, but the reason does not explain the assertion.

A mercury column of length 0.1m is filled in its middle and in rest two parts air is filled at atmospheric pressure. When tube is turned to vertical position, then displacement of mercury will be (standard pressure = 0.76 m of Hg) A tuning fork produces waves in a medium.
