What do you mean by the term reflection of light ?
Figure shows an incident ray AO and the normal ON on a plane mirror. The angle which the incident ray AO makes with mirror is 30°. (a) Find the angle of incidence. (b) Draw the reflected ray and then find the angle between the incident and reflected rays.
The diagram in Figure shows a point object P in front of a plane mirror MM1.
(a) Complete the diagram by taking two rays from the point P to show the formation of its image.
(b) In the diagram, mark the position of eye to see the image.
(c) Is the image formed real or virtual? Explain why?
Why are infinite images not seen when two plane mirrors are facing each other?
A converging mirror, forms three times magnified virtual image when an object is placed at a distance of 8 cm from it. Calculate:
- the position of the image
- the focal length of the mirror.
Copy the figure. By taking two rays from point A, show the formation of image. State four characteristics of the image.
What is a real image?
Complete the ray diagram to show the image observed by the eye after reflection in the following figure.
