Answer to Question #153446 in Optics for pretty

Question

write a short note on sign convention for spherical refracting surface

Answer 1

Answer

According to theory of Physics we can explain as the Sign Convention for refracting spherical surfaces: When the object faces a convex refracting spherical surface, the radius of curvature r should be taken as positive.

When it faces a concave refracting spherical surface,the radius of curvature r should be taken as negative.
