refraction, reflection, diffraction Flashcards
because i somehow manage to always fck em up
1
Q
refraction
A
when light passes a boundary between two different transparent media at an angle resulting in a change of direction
2
Q
Less dense to more dense (refraction)
A
Bends towards the normal
3
Q
More dense to less dense (refraction)
A
Bends away from the normal
4
Q
What causes change in direction?
A
the change in speed
- when light passes more dense substance the rays will slow down
5
Q
what properties change during refraction
A
Speed and wavelength
(frequency stays the same)
6
Q
law of reflection
A
angle of incidence = angle of reflectionwh
7
Q
when an object is reflected in a plane mirror, the image will be:
A
- same size as object
- same distance behind mirror as object is in front
- virtual
