SHM

2. wave Wave consisting of a periodic disturbance or vibration that takes place in the same direction as the advance of the wave.
4. interference A type of interference that occurs at any location along the medium where the two interfering waves have a displacement in the opposite direction.
7. The spreading of waves around obstacles.
10. point A point at which rays of light or other radiation converge
11. wave Motion in which all points on a wave oscillate along paths at right angles to the direction of the wave's advance
13. The maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position.
14. The number of waves that pass a fixed point in unit time;
15. waves Waves that are created as a result of vibrations between an electric field and a magnetic field.
17. Relatively large selective response of an object or a system that vibrates in step or phase, with an externally applied oscillatory force

1. The distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave
3. motion A motion repeating itself
5. The change in direction of a wave passing from one medium to another caused by its change in speed.
6. interference The interference of two or more waves of equal frequency and phase, resulting in their mutual reinforcement and producing a single amplitude equal to the sum of the amplitudes of the individual waves.
8. A disturbance in a medium that carries energy without a net movement of particles.
9. The substance that transfers the energy, or light from one substance to another substance or from one place to another or from one surface to another.
12. Abrupt change in the direction of propagation of a wave that strikes the boundary between different mediums.
16. The time it takes something to happen
