Question

what are the signs convenient to be followed for the applications of refraction at curved surfaces and through lens​

Answer 1

Certain sign convention  are needed to be followed due to refraction at curved surface and through the lenses.

Explanation:

• The sign convention of focus of convex lens is positive and concave lens is negative.

• In addition to this by default the object should be placed at the left of the mirror of the lens. It is taken to be at a particular distance from the optical centre which is considered as the axis.

• The left of the convex mirror of the concave mirror is taken negative and the the right hand side is taken positive
