What type of mirror can be used to obtain a real image of an object?
A concave mirror forms a real image of an object placed in front of it at a distance 30 cm, of size three times the size of object. Find
- the focal length of mirror
- position of image.
Define the term principal focus in case of convex mirror. Draw a convex mirror and show its principal focus and focal length clearly.
Define the term Aperture.
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.
