200
it contained colour
What did the light its self contain
200
objects dont produce their own light
why do objects appear black in the dark
200
light that you can see is an example of a form of energy
What is radiant energy
300
the height of a wave crests or depth of a wave trough,as measured from its rest position
What is amplitude
300
is the resault of all the different colours of light mixing
What is white light such as sunlight
300
refraction occurs
what occurs when light a wave passes from one material to another
300
used in radiation therapy to kill cancer cells
What is a gamma ray
400
matter in the medium moves back and forth the same direction that the wave travels
What is a compression wave
400
english scientist sir Isaac Newton
who discovered white light that was made from a spectrum of different colours
400
occurs when a light wave bounces off an object
What is what is a reflection

are used for broadcasting radio and television signals
What is what are radio waves used for
500
water waves and seismic waves
What is a combination of transverse and compression waves
500
what happened to the light if one colour is removed from the spectrum
it contained colour
500
this is light
a type of wave that travels through empty space and transfers energy from one place to another
