Is a convex lens?
A convex lens is also known as a converging lens. A converging lens is a lens that converges rays of light that are traveling parallel to its principal axis. They can be identified by their shape which is relatively thick across the middle and thin at the upper and lower edges.
What is a lens in physics?

What is a double concave lens?
Bi-Concave (Double-Concave) lenses have equal radius of curvature on both sides of the lens and function similarly to plano-concave lenses by causing collimated incident light to diverge.
What is the focal length of a double convex lens?
Answer: The focal length of a double convex length is 50 cm. Hence, the focal length of a double convex length is 50 cm.
Is V positive for convex lens?
‘v’ is always positive for convex mirror & concave lens. Distances measured from the optic center to the right of the lens are considered +ve and t from optic center to the left are -ve.
What are examples of concave lenses?
There are many examples of concave lenses in real-life applications.
- Binoculars and telescopes.
