Optics
The size of the image, if an object of $$2.5$$m height is placed at a distance of $$10$$ cm from a concave mirror is: (Take radius of curvature of concave mirror $$=30$$ cm)
The image formed by a concave mirror is observed to be virtual, erect and larger than the object. Where should be the position of the object?
When the position of object is between the pole of mirror and its principal focus, the image formed by a concave mirror is observed to be virtual, erect and larger than the object.
The size of the image, if an object of $$2.5$$m height is placed at a distance of $$10$$ cm from a concave mirror is: (Take radius of curvature of concave mirror $$=30$$ cm)
Given a point source of light, which of the following can produce a parallel beam of light
If an object is placed $$10\ cm$$ infront of a concave mirror of focal length $$20\ cm,$$ the image will be
Rays from Sun converge at a point 15 cm in front of a concave mirror. Where should an object be placed so that size of its image is equal to the size of the object ?
A man standing in front of a special mirror finds his image having a very small head, a fat body and legs of normal size. What is the shape of: (a) top part of the mirror? (b) middle part of the mirror? (c) bottom part of the mirror? Give reasons for your choice.
