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?

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
