Q

Absorbed

A

Taken in

21
Q

thermal

A

relating to heat

22
Q

Density

A

the degree of compactness of a substance

23
Q

deciduous

A

describes plants that lose their leaves during autumn and winter

24
Q

insulator

A

poor conductor

25
Q

conductor

A

poor insulator

26
Q

luminous

A

releasing its own light

27
Q

incandescent

A

objects that emit light when they are hot ( when you heat the 1000 degree knife it glows

28
Q

bioluminescent

A

living things that release light energy

29
Q

scattered

A

light sent in many directions by small particles within a substance

30
Q

visible spectrum

A

different colours that combine to make up white light

31
Q

dispersion

A

separation of the colours that make up white light. Each colour is bent differently when it enters or leaves a glass prism.

32
Q

electromagnetic radiation

A

the radiant energy such as radio waves, infrared, visible light, X-rays

33
Q

electromagnetic spectrum

A

complete range of wavelengths of energy radiated as electric and magnetic fields

34
Q

radio waves

A

low energy electromagnetic waves with a much lower frequency and longer wavelength than visible light

35
Q

infra-red radiation

A

low energy electromagnetic waves with a much lower frequency and longer wavelength than visible light

36
Q

ultraviolet radiation

A

invisible radiation similar to light but with a slightly higher frequency and more energy

37
Q

X-rays

A

high energy electromagnetic waves that can be transmitted through solids and provide information about their structure

38
Q

gamma rays

A

high energy electromagnetic radiation produced during nuclear reaction

39
Q

vibrations

A

an instance of vibrating

40
Q

compression

A

the process of pushing a material into itself

41
Q

rarefactions

A

in sound waves, the layers of air particles that are spread apart

42
Q

sound waves

A

vibrations of particles in the air

43
Q

frequency

A

number of vibrations in one second, or the number of wavelengths passing in one second

44
Q

hertz

A

unit of frequency; its abbreviation is Hz. One hertz is equal to one vibration every second.

45
Q

pitch

A

the highness or lowness of a sound. The pitch that you hear depends on the frequency of the vibrating air.

46
Q

wavelength

A

distance between two neighbouring crests or troughs of a wave. This is the distance between two particles vibrating in step.

47
Q

amplitude

A

maximum distance that a particle moves away from its undisturbed position

48
Q

reverberation

A

longer-lasting sound caused by repeated reflection from hard surfaces
