1.	a convex and concave lens of the same power are kept in contact i) what is the power of the combination ii) how does the combination of lenses behave like
Answer» TION:When TWO LENSES are kept in contact, powers of the lenses are simply ADDED. Power of a lens is positive for convex lens and negative for concave lens. Numerically power of a lens is given by 100f were f is focal length in centimeters.thank you
