NEET Physics: Waves — MCQ Test 7

Q6. In a standing wave formed on a string fixed at both ends, what is the condition for the position of nodes?

Q7. What is the primary source of restoring force for transverse waves on a stretched string?

Q8. Two strings produce beats of 6 Hz. One has a frequency of 384 Hz. When the tension in the second string is decreased, the beat frequency becomes 4 Hz. What was the original frequency of the second string?

Q9. Two waves \( y_1 = 3 \sin (4x - 10t) \) and \( y_2 = 3 \sin (4x - 10t + \pi/2) \) interfere. What is the amplitude of the resultant wave?

Q10. Two strings produce beats of 3 Hz. One has a frequency of 288 Hz. When the tension in the second string is increased, the beat frequency becomes 1 Hz. What was the original frequency of the second string?

Q11. A string of length 1.5 m and mass 0.03 kg has a wave speed of 60 m/s. What is the tension in the string?

Q12. A stationary wave is given by \( y = 0.06 \sin (\frac{\pi x}{4}) \cos (120\pi t) \), where \( x \) and \( y \) are in meters and \( t \) in seconds. What is the wavelength?

Q13. Why does a wave reflect with no phase change at a free end?

Q14. Two strings produce beats of 6 Hz. One has a frequency of 300 Hz. When the tension in the second string is decreased, the beat frequency becomes 4 Hz. What was the original frequency of the second string?

Q15. A string of length 0.8 m is fixed at both ends. If the speed of the wave is 40 m/s, what is the frequency of the second harmonic?
