Assertion A diverging lens (in air) cannot be made more diverging whatever be the medium we choose completely immerse the lens.
Reason The minimum refractive index of any medium is 1.

A

2 cm upwards

B

2 cm downwards

C

1 cm upwards

D

1 cm upwards

Text Solution

Verified by Experts

The correct Answer is:
C
(c ) Given, n=1.5, and `h_(o)=3cm`
Refractive index, `n=h_(o)/h_(i) rArr 1.5=3/h_(i)`
Apparent depth , `h_(i)=3/1.5=2 cm`
Hence, 3-2=1 cm upwards.

Light is incident on the thin lens as shown in figure. The refractive index of the material of the lens is mu_(2) . The radii of curvature of both the surfaces are R. The refractive index of the medium of left side is mu_(1) , while that of right side is mu_(3) . What is the focal length of the lens?

A lens behaves as a converging lens in air and a diverging lens in water. The refractive index of the material is (refractive index of water =1.33 )

A diverging lens is made of material with refractive index 1.3 and has identical concaves surfaces of radius 20 cm. The lens is immersed in a transparent medium with refractive index 1.8. (a) What is now the focal length of the lens? (b) What is the minimum distance taht an immersed object must be from the lens so that a real image is formed?

A thin convex lens of refractive index 1.5cm has 20cm focal length in air. If the lens in completely immersed in a liquid of refractive index. 1.6, then its focal length will be

A thin convex lens which is made of glass (refractive index 1.5) has a focal length of 20 cm. It is now completely immersed in a transparent liquid having refractive index 1.75. Find the new focal length of the lens.

Assertion : Newton's rings are formed in the reflected system. When the space between the lens and the glass plate is filled with a liquid of refractive index greater than that of glass, the central spot of the pattern is bright. Reason : This is because the reflections in these cases will be from a denser to a rarer medium and the two interfering rays are reflected under similar conditions.

Assertion : A convex lens of glass (mu = 1.5) behave as a diverging lens when immersed in carbon disulphinde of higher refractive index (mu = 1.65) . Reason : A diverging lens is thinner in the middle and thicker at the edges.

Assertion : When light passes from one medium to another of different density the only quantity which is unchanged is its wavelength . Reason : The wavelength of light is not related to the refractive index of the medium .
