Laws of Reflection. From the Activity you performed, when you shine an incident light ray at a plane mirror, the light is reflected off the mirror and forms a reflected ray. This behaviour leads to the 2 laws of reflection The angle of incidence is equal to the angle of reflection
When a series of parallel incident rays strike a flat
If parallel incident rays were directed at an irregular surface, they will have different incidence angles.
The reflected rays will be reflected in many directions.
This is known as diffuse reflection
When your eyes detect reflected light from plane mirrors, your brain projects the light rays back in a straight line.
Real Images- mirrors can produce images that can be projected on a screen. A real image is ALWAYS inverted and appears in front of the mirror.
Virtual Image- mirrors can also produce images that cannot be projected on a screen. A virtual image is ALWAYS upright and appears behind the mirror.
Image of object
Is there any easier way?
Draw line & measure
Repeat lines behind mirror
3. Convex Mirrors- a diverging mirror where light rays that strike the mirror surface are reflected so that they diverge, or “go apart” and they never come to a point.
The image in a plane mirror appears to be backwards compared to how we view the object directly.
