Figure shows a concave mirror with its pole at P, focus F and centre of curvature C. Draw ray diagram to show the formation of image of an object OA.
The diagram below in Figure, shows a convex mirror. C is its centre of curvature and F is its focus. (i) Draw two rays from A and hence locate the position of image of object OA. Label the image IB. (ii) State three characteristics of the image.
Name the kind of mirror used to obtain:
A virtual and enlarged image
Upto what maximum distance from a concave mirror, the image can be obtained? What will be the location of object for it?
When an object of height 1 cm is kept at a distance 4 cm from a concave mirror, its erect image of height 1.5 cm is formed at a distance 6 cm behind the mirror. Find the focal length of mirror, by drawing.
Define the following term in relation to concave mirror.
Aperture
What do you understand by the term real image?
The diagram below shows the parallel rays incident on a convex mirror. C is the centre of the curvature of the mirror. By drawing the paths of the reflected rays, label the focus F and hence find the focal length of the mirror.
Complete the following diagrams shown in the below figure by drawing the reflected ray for each incident ray.
The minimum length of the mirror required to see the full image of the person is half ‘ of his height.
