What to Focus On
- A wave is a moving disturbance.
- In a wave, energy is transferred, not matter as a whole.
- Mechanical waves require a medium; they cannot travel through vacuum.
- Transverse waves: oscillations perpendicular to propagation.
- Longitudinal waves: oscillations parallel to propagation.
- Transverse waves need shearing stress support.
- Positive x-direction wave: y = a sin(kx - ωt + φ).
- Negative x-direction wave: y = a sin(kx + ωt + φ).
- Wavelength is the minimum distance between points in the same phase.
Common Mistakes to Avoid
A wave carries matter from one place to another.
Sound can travel through vacuum because it is a wave.
Transverse waves can travel in any medium, including gases and liquids.
