Angle of incidence
Angle between the normal and the incident ray
1 of 14
Angle of reflection
The angle between the reflected ray and the normal (line drawn at the 90 degrees to the reflecting surface)
2 of 14
Concave
Curving inwards rather than bulging outwards
3 of 14
Density
The ratio of mass to volume. It is usually measured in grams per cubic centimetre or grams per cubic decimetre
4 of 14
Diffraction
The spreading out of waves when they pass through a gap or around an obstacle
5 of 14
Longitudinal waves
A wave that moves in the same direction as the direction in which the particles are vibrating
6 of 14
Prism
A block of glass or other transparent material that disperses light to form a spectrum
7 of 14
Reflection
There is a reflection when waves bounce off a surface
8 of 14
Refraction
Process by which a waves changes in speed and sometimes direction upon entering a denser or less dense medium
9 of 14
Transverse wave
A wave that moves in a direction at right angles to the way in which the particles are vibrating
10 of 14
Uniformly
Evenly
11 of 14
Vacuum
A volume that contains no matter
12 of 14
Wavelength
The length of a single wave, measured form one wave crest to the next
13 of 14
White light
Light that is a mixture of all the frequencies of visible light, so it appears white
