11

Wave

Disturbance that carries energy from one location to another

12

The medium

Material the disturbance travels through

13

Wavelength

The distance between one crest to the next (λ)

14

Amplitude

The maximum displacement

15

Period

The time it takes on complete wavelength to pass a single point (T)

16

Frequency

Number of complete wavelengths that pass a single point in one second (f)

Measured in herts (Hz)

17

Speed equation

V = d/t = λ/T = λf

18

Speed of light in vacuum (V)

3.0 x 10^8

19

The angle of incidence is always equal to

Angle of reflection

20

SALT

S ize
A ttitude (inverted)
L (f)
T ype (real)

21

Concave mirror

Curved mirror with reflective surface on inside (can form real and virtual images)

22

Convex mirror

Curved mirror with reflective surface on outside (always forms virtual, small image)

23

Point C

Centre of curvature

24

Point F

Focal point

25

Real image is formed when

Light rays converge at the location of the image

26

Virtual image is formed when

Light rays diverge from a point

27

Index of refraction (n)

The ratio of the speed of light in a vacuum to the speed in a material (c)

28

Index of refraction equation (n)

n = c/v

29

Snells law

nisinθi = nrsinθr

30

How to solve for c using n = c/v

(c = nv)
