A concave mirror always forms a real image.
Give one use each of a concave and a convex mirror.
AB and CD, two spherical mirrors, from parts of a hollow spherical ball with its centre at O as shown in the diagram. If arc AB = `1/2` arc CD, what is the ratio of their focal lengths? State which of the two mirrors will always form virtual image of an object placed in front of it and why.
Explain the following term:
Incident ray
Draw diagram/diagrams to show them.
Name the kind of mirror used to obtain:
A virtual and enlarged image
Define the following term:
spherical mirror
Define the term Pole.
An object 10 cm high is placed at a distance of 20 cm in front of a spherical mirror of focal length 25 cm. By scale drawing find the nature, position, and magnification of the image in the following case:
Convex mirror
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.
