Question

what happens to focal length and power of convex lens in water it is immersed in water​

Answer 1

Answer:

Explanation:

after immersing of lens in water focal length of lens increases. A convex lens made of glass is immersed in water.As a result,its focal length will increase

Answer 2

Answer:

focal length depends upon refractive index of lens with respect to medium. hence, after immersing of lens in water focal length of lens increases. A convex lens made of glass is immersed in water.As a result,its focal length will increase.
