# The Electromagnetic Spectrum

?
Approximate the range of the wavelengths of the waves and give real life examples
10 000m to 10ˆ-16
1 of 6
State the speed of each wave in vacuum
3*10ˆ8 m/s
2 of 6
How are the waves produced?
By a moving charge (then they propagate themselves through space)
3 of 6
What is the smallest EM wave and what is its wavelength?
Gamma Rays . 1*10ˆ-15
4 of 6
State the 7 EM waves in order of their frequency and then wavelength
Gamma rays, X-rays, UV, Visible, Infra-Red, Microwaves, Radio (then reverse)
5 of 6
What is the danger of X-Rays? What is something more dangerous than them?
They ionise (remove) atoms and damage living tissue. Gamma rays are more ionising than them.
