A plane mirror is rotated through an angle about two different axes. For a given incident ray, it is found that the reflected ray in case turns through an angle but in other case, the reflected ray remains as it is. How is this possible ?
Important Questions on Reflection of Light
A concave mirror produces a real image twice the size of the object when placed at a distance of 22.5 cm from it. Where should the object be place so that the size of the image becomes three times the size of the object ?
A plane glass plate is kept between a point object and a convex mirror of focal length 20 cm. The distance of the glass plate from the mirror is 5 cm. Rays of light from the point source, after reflection at the convex mirror and also at the front face of the glass plate form images at the same position. Find the distance between the glass plate and the point source.
An object is kept at a distance of 40 cm from a convex mirror. At a distance of 25 cm from the object a plane mirror is so placed that it covers one half of the convex mirror. As a result, the two images produced by the curvature of the convex mirror ?
