282512 A water drop in air reflects the light rays as
(a)
(b)
(c)
(d)
Ans: c
Exp: C: Water droplet has higher refractive index than air because of its convex shape, it will converge the parallel beam of light.

282515 A thin lens made of glass of refractive index \(\mu=\) 1.5 has a focal length equals to \(12 \mathrm{~cm}\) in air. It is now immersed in water \(\left(\mu=\frac{4}{3}\right)\). Its new

282516 The working of which of the following is similar to that of a slide projector?

282517 A symmetric double convex lens is cut in two equal parts by a plane perpendicular to the principal axis. If the power of the original lens is 4D, the power of a cut lens will be

282518 The power of a lens, a short sighted person uses is \(-2 \mathrm{D}\). Find the maximum distance of an object which he can see without spectacles :
