What is the electromagnetic spectrum? - ANS-The range of
wavelengths or frequencies over which electromagnetic radiation
extends.
State the order of the electromagnetic spectrum (longest
wavelength and lowest frequency --> lowest wavelength and
highest frequency). - ANS-Radio waves, microwaves, infrared
radiation, visible light, ultraviolet, x-rays, gamma rays
, Red light has... - ANS-a low frequency and a long wavelength
Blue/purple light has... - ANS-a high frequency and a short
wavelength
Radio waves frequency - ANS-10 ^4 - 10 ^8 Hz
Microwaves frequency - ANS-10^10 Hz
Infrared frequency - ANS-10^13 Hz
Visible light frequency - ANS-10^15 Hz
Ultraviolet frequency - ANS-10^16 Hz
X-rays frequency - ANS-10^18 Hz
Gamma rays' frequency - ANS-10^20 Hz
Radio waves - ANS-- Electromagnetic waves with the longest
wavelengths and lowest frequencies - Emitted by radio and TV
transmitters
- Used to send radio and TV programmes
- Detected by aerials and radios/TVs
