A concave mirror produces a real image of height 2 cm of an object of height 0.5 cm placed 10 cm away from the mirror. Find the position of the image and focal length of the mirror.

A perticular spherical mirror forms images of the same size when the objects are placed 8 cm and 16 cm from the pole of the mirror. Determine the nature and focal length of the mirror. Also determine the magnification of the image.

A concave mirror forms a virtual image of twice the size of the object placed at a distance of 10 cm from the mirror. If the object is placed at a distance of 30 cm from the mirror where will the image be formed? Formed? What will be the nature of the image formed?

An object is placed perpendicularly on the principal axis of a concave mirror of focal length 25 cm and an image is formed at a distance of 100 cm in front of the mirror. Determine the position of the object and mangnification of the image.

A concave mirror forms an image of an object, magnified 4 times. When the object is moved through 5 cm along the axis of the mirror, the magnification of the image is 5. What is the focal length of the mirror?

A concave mirror of focal length 36 cm and a convex mirror of focal length 20 cm are placed face to face on the same axis at a distance of separation 80 cm. An object is placed at a distance 20 cm in front of the convex mirror. Determine the position of the images (i) first by the reflection in convex mirror and then in the concave mirror and (ii) first by the reflection in concave mirror and then in the convex mirror.

A concave mirror has radius of curvature r and focal length f. An object is placed at a distance u from the mirror. The condition under which an inverted image of the same size of the object will be formed is

A concave mirror forms a real image of height twice the size of the object. Now the object and the screen are so moved that a real image of height three times the size of the object is formed. If the displacement of the screen is 18 cm, determine the displacement of the object and the focal lenght of the mirror.

An object is placed just at the middle point between concave mirror of radius of curvature 40 cm and a convex mirror of radius of curvature 30 cm facing each other. The mirrors are situated 50 cm apart from each other. The mirrors are situated 50 cm apart from each other. Considering the first reflection occurs in the concave mirror, determine the position and nature of the image formed by this mirror. Next find the position and nature of the image formed by the convex mirror considering the first image for concave mirror as its object.

An object is placed exactly mid-way between a concave mirror and a convex mirror. The radius of curvature for each of them is 0.2 m. The mirrors are placed face to face and are 0.3 m apart. Find the position of the image formed by two successive reflections, the first one taking place at the concave mirror and then at the convex mirror.
