An image of size 1/n times the object size is formed in a convex mirror. If r is the radius of curvature of the mirror what would be the object distance?

An image of size (1)/(n) times that of the object is formed in a convex mirror. If r is the radius of curvanture of the mirror, calculate the object distance.

A virtual image of half the size of the object is formed by a convex mirror at a distance of 30 cm from the object. What is the radius of curvature of the mirror?

The sun subtends an angle (1^(@))/(2) at the pole of a concave mirror. If the radius of curvature of the mirror is 15 m , what will be the size of the sun's image formed by the mirror?

An object of length 5cm is placed perpendicularly on the principal axis at a distance of 75cm from a conacave mirror. If the radius of curvature of the mirror is 60cm, calculate the image distance and its hieght.

An object is approaching a convex mirror. The ratio of the velocity of the object and that of the object image which is m times magnified is

A real and inverted image of the same size is formed by a concave mirror when the object is placed-

The ratio of the size of the image to the size of the object is called-

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

The image of an object at a distance of 40 cm from a convex mirror is formed at a distance of 10 cm from the mirror . If the object begins to move towards the mirror with a velocity of 8 cm * s^(-1) what will be the velocity of the image?

The image formed by a convex mirror is one third of the object. If the focal length of the mirror is 30 cm, calculate the image distance.
