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.

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

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

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 ?

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
