Q1
What are stationary waves?
Answer: Option B
Explanation: Stationary waves are formed by the superposition of two waves of same frequency and amplitude traveling in opposite directions.
Q2
In stationary waves, the points where amplitude is maximum are called:
Answer: Option B
Explanation: Antinodes are points of maximum amplitude in stationary waves.
Q3
In stationary waves, the points where amplitude is zero are called:
Answer: Option A
Explanation: Nodes are points of zero amplitude in stationary waves.
Q4
Which of the following statements about stationary waves is correct?
Answer: Option C
Explanation: Energy is not transmitted in stationary waves, it remains confined between nodes.
Q5
The distance between two consecutive nodes in a stationary wave is equal to:
Answer: Option B
Explanation: Distance between two consecutive nodes is λ/2.
Q6
Stationary waves are formed when:
Answer: Option C
Explanation: Stationary waves result from interference of two identical waves moving in opposite directions.
Q7
In a stationary wave, the phase difference between two particles in adjacent loops is:
Answer: Option C
Explanation: Particles in adjacent loops vibrate in opposite phase (180° difference).
Q8
The number of antinodes in a stationary wave of length L with both ends fixed is:
Answer: Option A
Explanation: For a string fixed at both ends, number of antinodes equals the harmonic number.
Q9
Which instrument works on the principle of stationary waves?
Answer: Option B
Explanation: Sitar produces musical notes based on stationary wave patterns.
Q10
In a stationary wave, all particles between two nodes:
Answer: Option A
Explanation: Particles between two nodes vibrate in phase with each other.
