releasing its own light
Luminous
describes objects that emit light when they are hot
incandescent
describes living things that release light energy
bioluminescent
describes light sent in many directions by small particles within a substance
scattered
different colours that combine to make up white light; they are separated in rainbows
visible spectrum
separation of the colours that make up white light. Each colour is bent differently when it enters or leaves a glass prism.
dispersion
the radiant energy such as radio waves, infrared, visible light, X-rays and gamma rays released by magnetic or electric fields
electromagnetic radiation
complete range of wavelengths of energy radiated as electric and magnetic fields
electromagnetic spectrum
low energy electromagnetic waves with a much lower frequency and longer wavelength than visible light
Radio waves
low energy electromagnetic waves with a much lower frequency and longer wavelength than visible light
infra-red radiation
invisible radiation similar to light but with a slightly higher frequency and more energy
ultraviolet radiation
high energy electromagnetic waves that can be transmitted through solids and provide information about their structure
X-Rays
high energy electromagnetic radiation produced during a nuclear reaction
gamma rays
