Q
Laws of reflection
A
Ray of incidence . Normal, ray of reflection all lie on the same plain
Angle of incidence is equal to angle of reflection
1
Q
Reflection
A
Light bounces off an object and this reflection of light enters the eye, it stimulates retina and cause optic nerve to inform brain of object you are seeing
2
Q
Real image
A
Caused by actual intersection of light
3
Q
Virtual image
A
Caused by apparent intersection of light
4
Q
Parralaz
A
Avoid in experiments; different in apparent positions of an object viewed along 2 different lines of sight
5
Q
Concave mirror formula
A
If real image - 1/u + 1/v = 1/f
If virtual image - 1/u -1/v = 1/f
6
Q
Magnification in relation to u & v formulae
A
M = v height / u height
M is always positive
7
Q
Convex mirror formulae
A
1/u - 1/v += -1/f
