If a sonometer has a fundamental frequency of 450HZ, what is the frequency of the fifth overtone?
2700Hz
456Hz
444Hz
75Hz
Correct answer is A
5th Overtone = 6fo = 6 x 450 = 2700Hz
What is the velocity of sound at 100 oC if the velocity of sound at 0 oC is 340ms -1?
497m-1
440m-1
397m-1
240m-1
Correct answer is C
\(V \propto \sqrt{T}\)
⇒ \(\frac{V_{1}}{\sqrt{T_{1}}} = \frac{V_{2}}{\sqrt{T_{2}}}\)
Using the above formula, we get
\(V_{2} \approxeq 397ms^{-1}\)
