an object is placed 18 cm in front of a mirror and if the image is formed at 4 cm to the right of the mirror calculate its focal

Mirror Formula (Convex Mirror) - Let AB be an object placed on the principal axis of a convex mirror of focal length f. u is the distance between the object and the mirror and v is the distance between the image..

It has been found that if the mirrors are inclined at an angle q then the number of images is given by the relation If is not a whole number, then the number of images will be rounded off to the nearest integer. This can be verified by actual drawing. If the mirro..

A formula giving the relation between focal length of the mirror, object distance, image distance and radius of curvatur..

When the Object is Placed Between Infinity and the Pole of the Mirror - The image is Formed between the pole and the focus Erect Diminished Virtu..

When the Object is at Infinity - When an object is placed at infinity, the rays coming from it are parallel to each other. Let us consider two rays, one striking the mirror at its pole and the other passing through the center of curvature. The ray which is in..

To concentrate solar radiations in solar heating devices. For this the food or substance that has to be heated is placed at the focus of a large concave reflector. After reflection, sun light converges on the substance and heats it. The following table gives the position, ..

An object seen through a telescope is in the form of a right triangle. If the actual height and base of the object is 28 cm and 39 cm and the height was 3 cm through the telescope, then find the length of the base of the triangle..

When an object is placed at infinity, the rays coming from it are parallel to each other. Let us consider two rays, one striking the mirror at its pole and the other passing through the centre of curvature. The ray which is incident at the pole gets reflected accordin..

The fractional part of these materials which is submerged in water is numerically equal to their density in grams per cubic centimeter. As they float, some sink deeper than the others. Blocks which sink more displace more water than those that sink less. When the heights of the blocks abo..
