Answer 1

i hope it's help u........xd

Answer 2

Answer:

${\huge{\boxed{\red{\mathcal{Hello}}}}}$

The focal length of each lens can be calculated using a simplified thick lens equation. f= R/(n-1), where n is the index of refraction and R is the radius of curvature of the lens surface. These lenses are fabricated from N-BK7, which has an Abbe Number of 64.17; this value is an indicator of the dispersion.
