Define power of a convex lens. What is its unit?

The principal focus of a convex lens is virtual . True/False

The radius of curvature of the convex surface of a planoconvex lens is 12 cm and its refractive index 1.5. If the plane face of the lens is silvered, then the distance from the lens at which parallel rays incident on its convex surface converge is

A ray of light is going towards the focus of a convex lens. Draw a ray digram to show the path of this ray of light after refraction through the lens.
