6.6.2.1 Types of Electromagnetic Waves Flashcards
1
Q
What are electromagnetic waves?
A
- transverse waves that transfer energy from source of waves to absorber
2
Q
What do electromagnetic waves form?
A
- continuous spectrum
3
Q
What do all types of electromagnetic waves have in common?
A
- travel at same velocity through a vacuum or air
4
Q
What are waves that form the electromagnetic spectrum grouped into?
A
- terms of wavelength and frequency
5
Q
How are the electromagnetic waves ordered?
A
- long to short wavelength
- low to high frequency
6
Q
What is the order of the groups?
A
- radio
- microwave
- infrared
- visible light (red to violet)
- ultraviolet
- x-rays
- gamma rays
7
Q
What type of electromagnetic waves can our eyes/retina detect?
A
- only visible light
- so detect limited range of EM waves
8
Q
What happens as wavelength decreases?
A
- frequency increases
9
Q
What happens as frequency increases?
A
- energy of wave increases
