A standing wave having 3 nodes and 2 antinodes is formed between two atoms having a distance \(1.21{\mkern 1mu} \,\mathop A\limits^{\;\;^\circ } \) between them. The wavelength of the standing wave is

Assertion : For the formation of stationary waves the medium must be bounded having definite boundaries Reason : In the stationary wave,some particles of the medium remain permanently at rest.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
The formation of stationary waves typically occurs in a bounded medium (though not too confined). At nodes,statement of reason is correct. So correct option is (2).

Assertion : When we start filling an empty bucket with water, the pitch of sound produced goes on decreasing. Reason : The frequency of man voice is usually higher than that of woman.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
A bucket, acting as a closed-end pipe, produces sound with a frequency (pitch) determined by \(v / 4 \mathrm{~L}\), where \(\mathrm{L}\) is the water depth. As the water level rises, \(L\) decreases, and also the pitch increases. Women's voices generally have higher frequencies than men's. So correct option is (4).

If the velocity of sound in air is \({300 {~m} / {s}}\), then the distance between two successive nodes of a stationary wave of frequency 1000 \({H_Z}\) is
1 10 \(cm\)
2 20 \(cm\)
3 15 \(cm\)
4 30 \(cm\)
Explanation:
Here, \({v_S} = 300\;m\;{s^{ - 1}}v = 1000\;Hz\) \(\therefore \quad \lambda = \frac{{{v_S}}}{{\dot v}} = \frac{{300}}{{1000}} = 0.3\,\;m\) Hence distance between two successive nodes \( = \frac{\lambda }{2} = \frac{{0.3}}{2} = 0.15\,\;m\) or \(15\,cm.\) So correct option is (3)

\(150,225,300,375\), is a series of resonant frequency. Which frequency is missing lower than \(400\;Hz\)
1 350
2 250
3 75
4 200
Explanation:
Series of resonant frequency must be integral multiple of fundamental frequency. This series is integral multiple of \(75\;Hz\). Hence missing frequency is \(75\;Hz\)
