- Waves - Physics
- sound waves
- can only travel through a solid, liquid or gas medium. they travel fastest in solids and slowest in gases.
- when the sound waves are compressed then the particles are tightly pushed together
- sound waves can be reflected, refracted and defracted
- diffraction, refraction and reflected
- diffraction - when waves meet a gap in a barrier - they carry on through the gap and then spread out after the gap.
- refracted - sound waves and light waves change when they cross through a substance/solid that has a different density
- reflected - light waves and sound waves reflect off surfaces when the angle of incidence + the angle of reflection
- types of waves
- longitudinal waves
- the oscillations travel in the same direction as the direction of travel and energy tranfer
- longitudinal waves are compressed(high pressure) and rarefaction (low pressure)
- sound waves are longitudinal waves
- Transverse waves
- the oscillations are at a right angle to the direction of travel and energy transfer
- light waves and other types of electromagnetic waves are transverse waves
- water waves are transverse waves
