Physics Light Flashcards
1
Q
Dispersion
A
When light slowdown at different speeds and cause it to move outwards at different angles
2
Q
Laterally inverted
A
When you see writing in the mirror but it’s the wrong way around
3
Q
Diffraction
A
The spreading out of a wave after it passes through a gap or around an obstacle
4
Q
Internal reflection
A
At a critical angle (or more/ 42•) the light will reflect off the semi circle block
5
Q
The electromagnetic spectrum
A
Radio Microwave Infrared Visible Ultra violet Xray Gamma
6
Q
Wave equation
A
Velocity=frequency x wavelength
7
Q
Refraction
A
If it goes through a less dense medium to a more dense medium the light ray bends towards the normal line
