'16' Marks Questions

1. Explain simple harmonic motion and discuss its characteristics. 

2. Discuss the phenomenon of sharpness of resonance. 

3. Deduce the wave equation for progressive wave. 

4. Derive the wave equation for standing waves.

5. Discuss analogy between electrical and mechanical oscillating system.

6. Explain Doppler's principle. Calculate the apparent pitch of a note due to the motion of source and the listener.

7. Discuss Doppler's effect in sound and obtain an expression for the apparent frequency of the note when the source and the listener are (i) moving towards each other, and (ii) moving away from each other.

8. Explain Doppler's effect. Explain the apparent frequency of a note when both the source and the listener are in motion, the medium being at rest.

9. Explain Doppler's effect. Find an expression for the ratio of the apparent frequency to the real frequency of the notes emitted when there is relative movement between the source and the listener.

10. State and explain Doppler's effect. Derive an expression for the change in frequency of a note when both the source of sound and the observer are in motion.

11. Explain Doppler's effect. Obtain an expression for the frequency of a note heard by an observer, when both the source and the observer are in motion towards each other.
