- Angle of reflection
- Point of incidence
- Reflected ray
State which surface of a plane mirror reflects most of the light incident on it: the front smooth surface or the back silvered surface.
Explain the following term:
Angle of incidence. Draw diagram/diagrams to show them.
The diagram below in figure shows an object XY in front of a plane mirror MM1 . Draw on the diagram, path of two rays from each point X and Y of the object to show the formation of its image .
In the figure is shown a concave mirror. A is a point on the principal axis. If an object O is kept at A, image is formed on A itself. Copy the diagram. Draw the image in the diagram. Is the image real or virtual?
