Figure Shows Two Rays A And B Being Reflected By A Mirror And Going As A` And B`. The Mirror                                                                               

Two plane mirrors are parallel to each other and spaced 20 cm apart. A luminous point object is placed between them and 5 cm from one mirror. What are the distances from each mirror of the three nearest images in each?    

If two adjacent walls and the ceiling of a rectangular room are mirror surfaced, then how many images of himself, a man can see?

Two bodies A and B are moving towards a plane with speeds VA and VB respectively as shown in figure. The speed of image of A with respect to the body B is

A beam of convergent light converges to a point 0.5 in front of the mirror after reflection at a convex mirror but in the absence of the mirror the beam converges to a point 0.2 behind the mirror. The radius of curvature of the mirrors is

A particle executes SHM in front of a concave mirror of radius 1 m, about the centre of curvature, with very small amplitude a. The amplitude of oscillation of the image is

A particle moves towards a concave mirror of focal length 30 cm along its axis and with a constant speed of 4 cm/ sec. What is the speed of its image when the particle is at 90 cm from the mirror?

A thin flat glass plate is placed in front of a convex mirror. At what distance b from the plate should a point source of light S be placed so that its image produced by the rays reflected from the front surface of the plate coincides with the image formed by the rays reflected from the mirror? The focal length of the mirror is f = 20 cm and the distance from the plate to the mirror a = 5 cm. How can the coincidence of the images be established by direct observation

A screen S is placed a distance b = 5 cm from a circular convex mirror as shown in figure. An object RP of height h = 3 cm is arranged a distance a = 5 cm from the screen. Where must an observer position himself to see the image of the entire object? What are the maximum dimensions of the object (with the given arrangement of the object, the mirror and the screen) for the mirror to reproduce and image of the entire object? The diameter of the mirror is d = 10cm.

A point object is placed at a distance of 30 cm from a convex mirror of focal length 30 cm. the image will form at                                                                                          

Figure shows three transparent media of refractive indices µ₁, µ₂ and µ₃. A point object O is placed in the medium µ₂. If the entire medium on the right of the spherical surface has refractive index µ₁, the image forms at O`. If this entire medium has refractive index µ₃, the image forms at O``. In the situation shown,
