Physics Revision Questions for Interference of Waves
1. What kind of interference will be formed by the two waves in the figure, which move towards each other? The initial distance between the two waves is 23 cm and the wavelength is 3 cm.
- Constructive interference
- Destructive interference
- Neither constructive nor destructive
- There is not enough information
Correct Answer: C
2. Which of the following pairs of waves can produce interference?
- A high water wave and a short water wave
- A loudspeaker and a light source
- A rope wave and a sound wave
- Two light waves with different frequencies
Correct Answer: A
3. Two parallel and coherent waves emitted by the same source fall on a screen after passing through a narrow gap as shown in the figure (for convenience, waves are represented by straight lines).
If the distances d1 and d2 travelled by the two waves after passing through the gap are 9.8 cm and 8.2 cm respectively and the wavelength is 4 mm, what kind of interference (if any) will occur at the point A on the screen?
- Constructive interference
- Destructive interference
- Neither constructive nor destructive
- There is not enough information
Correct Answer: A
