Question

How can you find the focal length of a convex lens by UV method
Explain with an experiment​

Answer 1

Answer:

focal length is the half of radius of curvature. so, the radius of curvature which can be denoted by R. formula becomes R/2

Step-by-step explanation:

for example,

if the radius of curvature of a convex lens is 16cm then by applying formula which is R/2 we cna get the focal length.

f=R/2

f=16/2

f=8 cm
