A boy looks at the image of an object in a plane mirror. He observes two images, a main bright one and the other faint. The observed images result from?
An object is placed 10cm from a converging lens of foal length 15cm. Calculate the magnification of the image formed
in the image above, an incident ray XY makes an angle of 15\( ^{\circ} \) with a fixed line AY, which is normal to surface of a plane mirror if the mirror is turned as indicated by the arrow through \( 40^{\circ} \), what angle will the reflected ray make with AY
the arrow represents an object in front of a convex mirror whose focal points are X and Y. The image formed is
An object is placed in front of a concave mirror whose radius of curvature is 12cm. If the magnification of the Image produced is 1.5, how far is the object from the mirror?
