An observer is standing at the position x=20 m listening to the glottal wave shown. What repeat time does the observer hear? Select one: a. 2/3 s b. 1/6 s c. 1/56 s d. 1/223 s e. none of these

An observer moves towards a stationary source of sound of frequency $n .$ The apparent frequency heard by him is $2 n$. If the velocity of sound in air is $332 \mathrm{~m} / \mathrm{sec}$, then the velocity of the observer is: (a) $166 \mathrm{~m} / \mathrm{sec}$ (b) $664 \mathrm{~m} / \mathrm{sec}$ (c) $332 \mathrm{~m} / \mathrm{sec}$ (d) $1328 \mathrm{~m} / \mathrm{sec}$

Waves
"A source of sound S emitting waves of frequency 100 Hz and an observer O are located at some distance from each other. The source is moving with a speed of 19.4 ms–1 at an angle of 60º with the source observer line as shown in the figure. The observer is at rest. The apparent f r e q u e n c y observed by the observer (velocity of sound in air 330 ms–1) is: (a) 97 Hz (b) 100 Hz (c) 103 Hz (d) 106 Hz"

"An observer at rest near the source of the sound of frequency 684 Hz. Another the source of the sound of 676 Hz moving toward the observer at 2 m/s. If the speed of the sound waves in air is 340 m/s, then what is the beat frequency heard by the observer."
