Edexcel iGCSE Physics – Waves All Answers Correct
1. Explain what waves accomplish.
- Waves transfer energy and information from one location to another without moving matter.
2. Define transverse waves.
- Transverse waves are waves where the medium oscillates perpendicular to the direction of wave
propagation.
3. Define longitudinal waves.
- Longitudinal waves are waves where the medium oscillates parallel to the direction of wave
propagation.
4. What is meant by the term "medium"?
- The medium refers to the substance through which waves travel.
, 5. Define oscillation.
- Oscillation occurs when a substance moves back and forth around a fixed point.
6. Explain displacement in the context of waves.
- Displacement refers to how far a wave has moved from its equilibrium or rest position.
7. Define wavelength.
- Wavelength is the distance between two consecutive points of similar displacement in a wave.
8. What is the symbol used to represent wavelength?
- The symbol for wavelength is lambda (λ).
9. In what units is wavelength measured?
