Q

Reflection

A

Waves bouncing off a surface

Refraction

A

Wave changes direction and speed as it travels through a medium

18
Q

Specular reflection

A

Flat surface reflection (parallel normals)

19
Q

Diffuse reflection

A

Normals are not parallel so rays diverge

20
Q

Diffraction

A

Wave spreads out as it enters a gap

21
Q

Convex lens

A

Bugle creates converging waves

22
Q

Concave lens

A

Bend in diverges rays

23
Q

TIR

A

Total Internal Refraction (wave remains inside glass as it propagates)

24
Q

Dispersion

A

Separation of white light into a spectrum

25
Q

EM radiation

A

Electromagnetic radiation, oscillating electric and magnetic fields

26
Q

Polarisation

A

When all oscillations of the field are limited to one plane only

27
Q

Node

A

For a stationary wave, a point where the amplitude is always zero
