Study Notes
Waves
- The upper part of a wave is called the crest.
- The front edge of a wave is called the wavefront.
Reflection
- The change in direction of a light ray when it meets an obstacle is called reflection.
- The line drawn at a right angle at the point the incident ray strikes the reflecting surface is called the normal.
Wavelength
- The distance between one positive amplitude and the next is called the wavelength.
Trough
- The lower part of a wave is called the trough.
