Q.
A point source of light is kept at 50 cm from a concave mirror of focal length 30 cm. A convex lens of focal length 12 cm is placed between source and mirror as shown in figure at distance 'x' from source. Possible values of 'x' so that ray of light emerging from source after refraction from lens then reflection from mirror and then again refraction from lens can reach source is
Q.
A source of light is located from a convergent lens of focal length f=30 cm at a distance double the focal length of the convergent laws. At what distance from the lens should a flat mirror be placed so that the rays reflected from the mirror are parallel after passing through the lens for the second time. (in cm)
