Sample questions

1. 1.Regarding reflection of waves, which statement is correct?
   • A.At a rigid boundary the reflected wave undergoes a phase change of pi, while at an open boundary there is no phase change
   • B.At both rigid and open boundaries there is a phase change of pi
   • C.At a rigid boundary there is no phase change, while at an open boundary the phase changes by pi
   • D.Reflection never produces any phase change
2. 2.Assertion (A): Newton's formula gives a speed of sound in air about 15% smaller than the measured value. Reason (R): Newton assumed the pressure variations during sound propagation are isothermal rather than adiabatic.
   • A.Both A and R are true and R is the correct explanation of A
   • B.Both A and R are true but R is NOT the correct explanation of A
   • C.A is true but R is false
   • D.A is false but R is true
3. 3.Assertion (A): Longitudinal waves can propagate in solids, liquids and gases. Reason (R): All elastic media, including fluids, can sustain compressive strain.
   • A.Both A and R are true and R is the correct explanation of A
   • B.Both A and R are true but R is NOT the correct explanation of A
   • C.A is true but R is false
   • D.A is false but R is true
4. 4.Matter waves are associated with:
   • A.constituents of matter such as electrons, protons and atoms
   • B.only the surface of liquids
   • C.only stretched strings
   • D.only the air around us
5. 5.Two sitar strings A and B produce beats of frequency 5 Hz. When the tension of B is slightly increased, the beat frequency decreases to 3 Hz. If A is 427 Hz, the original frequency of B is:
   • A.422 Hz
   • B.432 Hz
   • C.424 Hz
   • D.430 Hz
