Flashcards in Sound And Light Deck (32):
1

Refraction

The bending of light waves when they down whilst going through a different medium

2

Plane mirror

A plain mirror reflects light perfectly(specular reflection)

3

Cornea

The cornea protects the eye

4

Lens

The lens refracts light so you can see

5

Retina

When the light hits here it sends the image to the brain

6

Speed of light

300,000,000 metres a second

7

Speed of sound

340 metres a second in air, 1500 m/s in a liquid and 5000 m/s in a solid.

8

Pitch

How high it is in Hz

9

Amplitude

The volume of a sound

10

Frequency

How high pitch it is

11

Medium

A different material

12

Spectrum

The colures in a rainbow

13

Wave

The transfer of energy

14

Ultrasound

Sound humans can't hear

15

Echo

Reflection of sound

16

Audible range

The range of what humans can hear

17

Vaccum

A place where there are no particles (eg. Space)

18

Convex lens

A convex lens converges light by refracting it

19

Concave lens

A concave lens diverges light by refracting it

20

Oscillation

This is when something moves back and forth continualy

21

Reverberation

This courses an echo

22

Trough

The top of a wave

23

Reflected ray

This is when light bounces of a plane mirror

24

Angle of refraction

The angle that is made when something is refracted

25

Incident ray

The ray that gets reflected

26

Specular reflection

Specular reflection is the mirror like reflection

27

Transversal wave

When the vibrations are at a right angle

28

Longitudinal wave

This is when the wave is parallel

29

Law of reflection

The incident ray and reflected rays angles compared to the normal are the same

30

Diffuse scattering

When the light hits a rough surface and scatters

31

Dispersion

the separation of white light into colours

32

Wave length

the distance over which the wave's shape repeats
