- Waves
- Transverse waves
- A transverse wave is one that vibrates, or oscillates.
- They vibrate at right angles to the direction in which the energy or wave is moving.
- Examples of transverse waves:
- Light waves
- Waves travelling on the surface of the water
- Waves on springs and strings
- Longitudinal waves
- A longitudinal wave is one which the vibrations, or oscillations, are along the direction in which the energy or wave is moving.
- Examples of longitudinal waves:
- Sound waves
- A slinky when you push and pull the end
- P-waves
- Examples of longitudinal waves:
- A longitudinal wave is one which the vibrations, or oscillations, are along the direction in which the energy or wave is moving.
- Diffracion
- If a barrier with a large gap is placed in the path of the waves, the majority of the waves passing through the gap continue through in a straight line.
- Speed = Frequency x Wavelength
- v = f x lambda
- Frequency = 1 ÷ Time
- f = 1 ÷ t
- Refraction
- If the boundary between shallow water and deep water is at an angle to the direction in which the waves are moving, the direction of the waves changes.
- We say that the waves have been refracted or have undergone refraction.
- Reflection
- When waves strike a straight or flat barrier, the angle at which they leave the barrier surface is equal to the angle at which they meet the surface.
- The waves are reflected at the same angle at which they struck
- Transverse waves
