282031 When an object is more along the principle axis of a concave mirror placed in air, the image coincides with the object if the object is $50 \mathrm{~cm}$ from the mirror. If the mirror is place at the depth of $20 \mathrm{~cm}$ in transparent medium, the image coincided with the object when the object is $40 \mathrm{~cm}$ from the mirror. The refractive index of the liquid is

1 $\frac{5}{4}$
2 $\frac{4}{3}$
3 $\frac{3}{2}$
4 $\frac{5}{3}$
Ray Optics

282032 For concave mirror, if the object is just beyond the focal length, the image formed is

1 real, inverted and magnified
2 real, inverted and diminshed
3 real, erect and magnified
4 real, erect and diminished

282033 An object is placed at a distance of $40 \mathrm{~cm}$ from a concave mirror of focal length $15 \mathrm{~cm}$. If the object is displaced through a distance of $20 \mathrm{~cm}$ towards the mirror, the displacement of the image will be

1 $30 \mathrm{~cm}$ towards the mirror
2 $36 \mathrm{~cm}$ away from the mirror
3 $30 \mathrm{~cm}$ away from the mirror
4 $36 \mathrm{~cm}$ toward the mirror

282034 Parallel rays of light entering a convex lens always converge at

1 Centre of curvature
2 The principle focus
3 Optical centre
4 Focal plane
