Pinhole Camera#!#Mirrors & Reflections

Which of the following statements are correct? (i) The shape of a shadow depends on the position of the source of light. (ii) A plane mirror can change the direction of light falling on it. (iii) A pinhole camera forms an erect image of an object on a screen. (iv) A shadow is formed when light passes through a transparent object .

STATEMENT-1: In high-quality optical devices, such as camera, binocular, periscope, et.c prisms are used in place of plane mirrors to reflect light. STATEMENT-2: In plane mirrors, reflections occur both in the front and rear (silvered) surfaces.

Two plane mirrors are placed perpendicular to each other. A ray strikes one mirror and after reflection falls on the second mirror. The ray after reflection from the second mirror will be

In a convex spherical mirror, reflection of light takes place at :

Suppose that the lower half of a concave mirror's reflecting surface is covered with an opaque non-reflecting material. What effect will this have on the image of an object placed in front of the mirror ?

A light ray incident on a plane mirror gets reflected from it. Another plane mirror is placed such that the reflected ray from the first mirror is incident on it If the reflected ray from the second mirror travels perpendicular to the indecent ray on the first mirror, determine the angle between two plane mirrors.

What letters of the English alphabet have reflectional symmetry (i.e.,symmetry related to mirror reflection) about.(a) a vertical mirror (b) a horizontal mirror (c) both horizontal and vertical mirrors

A convergent beam is incident on a convex mirror. Reflected light
