A cubicla room is formed with 6 plane mirrors. An insect moves along the diagonal of the floor with uniform speed. The speed of its image in two adjacent walls is `20 sqrt2 cm//s`.
Then the speed of the image formed on the roof is

A room (cubical) is made of mirros. An insect is moving along the diagonal on the floor such that the velocity of image of insect on two adjacent wall mirrors is 10(cm)/(sec) . The velocity of image of insect in ceiling mirror is

A person is in a room whose ceiling and two adjacent walls are mirrors. How many images are formed

A linear object AB is placed along the axis of a concave mirror. This object is moving towards the mirror with speed U. The speed of the image of the point A is 4U and the speed of the image of B is alSO 4U btu in opposite direction. If the center of the line AB is at a distance L from the mirror then find out the length of the object.

Uniform speed of 2 cm diameter ball is 20cm//s in a viscous liquid. Then, the speed of 1 cm diameter ball in the same liquid is

An observer moves towards a plane mirror with a speed of 2(m)/(sec) . The speed of the image with respect to the observer is

Establish relation between the speeds of object and image formed by a spherical mirror.

A plane mirror is placed with its plane at an angle 30^(@) with the y-axis. Plane of the mirror is perpendicular to the xy-plane and the length of the mirror is 3m. An insect moves along x-axis starting from a distant point, with speed 2 cm/s. The druation of the time for which the insect can see its shown image in the mirror is:

Daniel walks directly toward a plane mirror at a speed of 0.25 (m)/(s) . Determine the speed of the image relative to him.
