- Reflection, Refraction and Diffraction
- Reflection
- When waves are incident on the surface they can be reflected, transmitted or absorbed.
- An echo is heard when sound is reflected.
- When light rebounds of a surface and changes direction. It is reflected
- Refraction
- Refraction is the change of speed and direction of a wave when it goes from one
medium to another.
- Refraction doesn't
happen if the waves cross the boundary at an angle of 90°
- In that case they carry straight on
- Refraction doesn't
happen if the waves cross the boundary at an angle of 90°
- Refraction is the change of speed and direction of a wave when it goes from one
medium to another.
- Diffraction
- Diffraction occurs when a wave passes through a narrow opening.
- Diffraction is greatest when the gap is the same width as the wavelength.
- Diffraction occurs when a wave passes through a narrow opening.
