Question

If power of lens is positive so what kind of lens is that

Answer 1

Answer:

Given:

Power of lens is positive (+ve)

To find:

The kind of lens.

Explanation:

Power is defined as the capability to diverge/convergence a light ray. Higher the power, higher is the divergence or convergence.

$p \: = \frac{1}{f}$

p is the power, f is the focal length.

Now , if "f" is positive, then "p" is also positive.

f is positive in case of convex lens.

So ,

The given lens is convex lens.

Answer 2

Question :-

If power of lens is positive so what kind of lens is that -

Explanation :-

Q. What is power of lens ?

→ The ability of lens to change falling rays on it is called power of lens .

it can be divert or convert .

→ P = 1/F ( m )

• F is the focal length

• P is the power of lens

Unit of power of lens is Dioptre .

→ Concave lens has negative power .

→ Convex lens has positive power .

hence it is convex lens .
