Ray Optics

282025 A concave mirror of focal length ' $f_1$ ' is placed at a distance ' $d$ ' from a convex lens of focal length ' $f_2$ '. A parallel beam of light coming from infinity parallel to principal axis falls on the convex lens and then after refraction falls on the concave mirror. If it is to retrace the path, the distance ' $d$ ' should be

1 $2 f_1+f_2$
2 $\mathrm{f}_1+\mathrm{f}_2$
3 $-f_1+f_2$
4 $2 \mathrm{f}_1-\mathrm{f}_2$
Ray Optics

282026 For convex mirrors, whatever may be the position of the object, the image formed is always on the

1 same, side virtual, errect, magnified.
2 opposite side, real errect, magnified.
3 opposite side, virtual, errect diminished.
4 same side, real, errect, diminshed.
Ray Optics

282027 Convex lens always gives a real image if the object is situated beyond

1 Optic centre
2 Focus
3 Radius of curvature
4 Centre of curvature

282028 An object is placed at $9 \mathrm{~cm}$ in front of a concave mirror of radius of curvature $12 \mathrm{~cm}$. The following statement is true

1 The image is formed $36 \mathrm{~cm}$ behind the mirror
2 The image is $36 \mathrm{~cm}$ in front of the mirror
3 The image is magnified, virtual and erect
4 The image is magnified, real and erect
(e) The image is magnified, real and inverted

282029 A source is placed at a distance of $25 \mathrm{~cm}$ from a convex lens of focal length $15 \mathrm{~cm}$ (see the figure below). At what distance should a convex mirror of focal length $12 \mathrm{~cm}$ be placed so that the image is formed at the source?
