Cards in this deck (6)
- 1longitudinal wavesIn longitudinal waves, the oscillations are along the same direction as the direction of travel and energy transfer.Sound waves and waves in a stretched spring are longitudinal waves.
- 2Transverse wavesIn transverse waves, the oscillations (vibrations) are at right angles to the direction of travel and energy transfer.Light and other types of electromagnetic radiation are transverse waves.

- 4—REFRACTION =Sound waves and light waves change speed when they pass across the boundary between two substances with different densities, such as air and glass. This causes them to change direction.Refraction doesn't happen if the waves cross the boundary at an angle of 90° (called the normal) - in that case they carry straight on.

- 6—Sound waves and light waves reflect from surfaces. When waves reflect, they obey the law of reflection:
the angle of incidence equals the angle of reflection
