When 2 waves meet at at point the resultant displacement at that point is equal to the sum of the displacements of the individual waves
1 of 15
`Interference
Superposition of 2 progressive waves from coherent sources to produce a resultant wave with a displacement = to the sum of the individual displacements from the two waves
2 of 15
Constructive Interference
Superposition of 2 waves in phase so that the resultant wave has greater amplitude than the original wave
3 of 15
Destructive`Interference
Superposition of 2 waves in anti-phase so that the waves cancel each other out and the resultant wave has smaller amplitude than the original waves
4 of 15
Coherent
2 wave sources, or waves, that are coherent have a constant phase difference
5 of 15
Path difference
The difference in the distance travelled by two waves from the source to a specific point

Monochromatic Light
Light of a single frequency

Young's double slit equation
Find the wavelength of light

Stationery wave
A wave that remains in a constant position with no net transfer of energy and is characterised by its nodes and antinodes- also called a standing wave
9 of 15
Node
A point where the amplitude is always 0, for a stationery wave
10 of 15
Antinode
A point where the wave is at its highest amplitude, for a stationery wave.
