The incident ray, reflected ray and the normal all lie in the same plane.
Second Law of Reflection:
The angle of incidence is equal to the angle of reflection.

List the properties of a wave
- The source of any wave is a vibration or an oscillation.
- Waves transfer energy from one point to another.
- In waves, energy is transferred without the medium being transferred.
Define longitudinal wave
Longitudinal wave is a wave in which the movment of particles in the medium is parallel to the direction of a wave motion.
Define transverse wave
Transverse wave is a wave in which the movement of particles in the medium is perpendicular to the direction of a wave motion.
Define wavefront
Wavefront is an imaginary line on a wave that joins all points in the same phase.
Define amplitude
Amplitude is the maximum displacement of a particle in a wave from its rest position.
Define period
Period is the time taken to produce one complete wave.
Define wavelength
Wavelength is the shortest distance between any 2 points in a wave that are in phase.
Define frequency of a wave
Frequency of a wave is the number of complete waves produced per second.
Define specific latent heat of fusion
Specific latent heat of fusion refers to the amount of thermal energy required to change 1kg of a substance from solid to liquid, or vice versa, without a change in temperature.
