CLASS 11 PHYSICS OSCILLATIONS IMPORTANT CONCEPT BASED QUESTIONS
OSCILLATIONS 1. What is periodic motion? Give some examples. 2. What is oscillatory motion? Give some examples 3. State Fourier theorem. 4. Every oscillatory motion is necessarily periodic but every periodic motion need not be oscillatory. Justify. 5. Define harmonic functions. 6. Is the function sin⍵t + cos⍵t periodic? If yes, give the period. (⍵ is any positive constant). 7. What is simple harmonic motion? Give examples. 8. Give some important features of S.H.M. 9. Write down the differential equation for S.H.M. and give its solution. Also obtain an expression for time period of S.H.M. 10. Define the following: 1. Amplitude 2. Frequency 3. Angular frequency 4. Time period 5. Oscillation 6. Phase 7. Displacement 8. Epoch 11. Derive an expression for the displacement of a particle in S.H.M. 12. Derive an expression for the velocity of a particle executing S.H.M.. When is it (i) maximum and (ii) minimum? 13. Derive an expression for the acc...
