​

Answer 1

Answer:

hey mate here is our answer

Explanation:

AnSwer:

Focal length of the lens is 100 cm.

━━━━━━━━━━━━━━━━

✩GiVen:

Refractive Index = 1.5

R1 = 15 cm

R2 = 10 cm

✩To Find:

We need to find the focal length of convex lens.

✩SoluTion:

According to the formula,

Therefore, focal length is 100 cm.
