- the electromagnetic spectrum (in order of decreasing wavelength and increasing frequency and energy) is made up of:
radio waves, microwaves, infrared radiation, visible light, ultraviolet waves, xrays and gamma rays
- the human eye can only detect visible light, the wavelength of visible light ranges from about 350nm to about 650nm
- electromagnetic waves transfer energy from a source to an absorber
- the wave speed equation
wave speed = frequency x wavelength
