Question

1 1. Assertion: Property of converging of a convergent lens does not remain same
in all media

Reason: Property lens whether the ray is diverging or converging is
independent of the surrounding Medium


Pls give explanation also

Answer 1

Answer:

A is true but R is false

Explanation:

focal length and power changes in different medium

Answer 2

Answer:

Tip:

A convergent lens directs light to a spot near the lens' optical centre or axis.

Explanation:

1. A lens that provides a true image by converting parallel light beams to convergent light rays.
2. The picture is actual and inverted as long as the item is outside of the focus point.
3. The picture becomes virtual and upright when the item is inside the focus point.
4. A lens is a refractory transmissive optical device that alters the focus of a light beam.
5. The lens is known as a positive or converging lens in this scenario.

Step:

1. By refracting (bending) light rays twice, a double convex lens, also known as a converging lens, concentrates divergent, or unfocused, light rays from a distant object.
2. The rays converge at a focus point behind the lens as a result of the double bending, resulting in a clearer picture that may be seen or recorded.

Final answer:

1. When the refractive index of the media is larger than the refractive index of the lens material, yes, a convergent lens in one medium becomes divergent in another medium.
