NEET Physics: Waves — MCQ Test 9

Q6. Two strings produce beats of 3 Hz. One has a frequency of 400 Hz. When the tension in the second string is slightly increased, the beat frequency becomes 2 Hz. What was the original frequency of the second string?

Q7. Two waves of frequencies 496 Hz and 502 Hz interfere. How many beats are heard in 10 seconds?

Q8. A pipe open at both ends has a length of 0.8 m and resonates with a source of frequency 637.5 Hz. What is the harmonic number if the speed of sound is 340 m/s?

Q9. What is the effect on a standing wave’s frequency if the length of the vibrating medium is halved?

Q10. Two waves of frequencies 490 Hz and 495 Hz interfere. How many beats are heard in 8 seconds?
