Electro Magnetic waves Flashcards
1
Q
what type of waves are EM waves
A
transverse s waves
2
Q
what do EM waves transfer
A
energy from a source to absorber
3
Q
what can EM waves do that sound waves cannot
A
travel through vacuums
4
Q
in a vacuum what speed do ALL EM waves travel
A
3 x 10^8 m/s
5
Q
what is the trend in the EM spectrum as they get shorter in wavelength
A
the frequency increases and the wave length decreases
6
Q
what is the order for EM waves from largest wavelength to smallest
(least frequent to most)
A
radio waves
microwaves
infrared
visible light
ultraviolet
x - rays
gamma rays
7
Q
What is the relation of wavelength and frequency in em waves
A
inversely proportional (radio waves = big wave length but low frequency)
