A coin is kept in front of two plane mirrors inclined to each other. If 3 images of the coin are seen then what is the angle A between the mirrors?

A bird is sitting in front of two plane mirrors inclined at an angle of 60^@ to each other. How many images does the bird see in the mirror?

If we keep the mirrors parallel to each other, how many images will we see ?

Two plane mirrors are inclined at an angle of 40^@ between them. Number of images seen of a tiny object kept between them is

When a person stands in front of a plane mirror, how is the image formed? What is the nature of the image?

A convex mirror has a focal length of 18cm. The image of an object kept in front of the mirror is half the height of the object. What is the distance of the object from the mirror?

Solve the numerical problem A convex mirror has a focal length of 18 cm. The image of an object kept in front of the mirror is half the height of the object. What is the distance of the object from the mirror?

If two plane mirrors are parallel to each other, the object lying between them will have (n) number of images given by

Answer the following questions: When an object is kept at 50 cm in front of a concave mirror, Its real image is obtained at the same distance from the mirror. What is the focal length of the mirror?

An object is placed in front of a convex mirror at a distance of 50cm. A plane mirror is introduced covering the lower half of the convex mirror. If the distance between the object and the plane mirror is 30cm, it is found that there is no parallax between the images formed by the two mirrors. What is the radius of curvature of the convex mirror?
