Read each question carefully and answer to the best of your ability. Use complete sentences for short answer questions.
1. The principle of states that when two or more waves overlap, the resulting displacement is the sum of the individual displacements.
2. When waves combine to form a larger amplitude, it is called interference.
3. When waves combine to cancel each other out or form a smaller amplitude, it is called interference.
4. Which of the following best describes what happens when two waves meet and their crests overlap?
Destructive interference
Constructive interference
Refraction
Diffraction
5. What happens when the crest of one wave meets the trough of another wave of equal amplitude?
A larger wave is formed
The waves cancel each other out
The waves reflect
The waves change speed
6. Wave superposition only applies to light waves, not sound waves.
True
False
7. The amplitude of a resultant wave can be smaller than the amplitude of the individual waves.
True
False
8. Describe constructive interference in your own words. Provide an example.
9. Describe destructive interference in your own words. Provide an example.
10. Observe the image below showing sound waves. Imagine another identical wave is generated directly opposite to the first one, causing destructive interference. Draw the resulting wave on the lines provided.
