1.	If the power of a lens is +2.0 D, what does it imply?
Answer» Hola User__________________ Here is Your Answer..!!! _________________________ ⭐Actually welcome to the CONCEPT of the RAY OPTICS.. ⭐Basically we know that ... Power of a lens is the reciprocal of the focal length in metres.. ⭐So here , P = 1/f ⭐so the focal lenght of the lense will be f = 1/P ⭐we get the focal length as f = 1/2 ==》 f = + 0.5 m ⭐Now from here we can conclude that .. as the Focal length of the Given unknown lens is Positive 0.5 ... ⭐Then WE CAN CONCLUDE THAT THE GIVEN LENS IS A CONVEX LENS AS CONVEX LENS HAS ALWAYS A POSITIVE FOCAL LENGTH .. ______________________________ HOPE it helps u...☺
