What type of a spherical mirror is required to project the image of the flame of a candle on a wall 9 ft away from the flame? Determine the position of the mirror and its focal length.

An Object is placed at a distance of 90 cm from a screen. To cast an image of magnification 2 on the screen, what type of spherical mirror is required ? Determine the position of the mirror and its focal length.

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.

The image of a candle flame placed at a distance of 30 cm from a mirror is formed on a screen placed in front of the mirror at a distance of 60 cm from its pole. What is the nature of the mirror ? Find its focal length. If the height of the flame is 2.4 cm, find the height of its image. State whether the image formed is erect or inverted.

" If a spherical mirror is immersed in a liquid,its focal length will."

An object is at a distance of 10 cm from a spherical mirror and the image of the object is at a distance of 30 cm from the mirror on the same side as the object.Is the mirror concave or convex?What is its focal length?

The image of the flame of a candle due to a mirror is formed on a screen at a distance of 9cm from the candle. The image is magnified 4 times. Determine the nature, position 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.
