Properties of Waves
- Reflection
- All waves obey the
law of reflection
- i=r
- Angle of Incidence =
Angle of Reflection
- Refraction
- When a wave passes from a less
to more dense medium (air to
glass), it will bend.
- The wave bends
towards the normal
- When a wave passes from a more to less
dense medium (glass to air), it will bend
- The wave bends away from the normal
- Refraction occurs due to
the wave changing speed
- It slows down as it enters the glass
- Diffraction
- The Spreading
of waves
through a gap
- Diffraction is
increased if the gap is
narrow
- All waves obey
the wave
equation
- Velocity= frequency x wavelength
