REFLECTION OF LIGHT Similar Questions The focal length ofa converging lens are fvandfr for violet and red light respectively. View Solution If f(V) and fR are the focal lengths of a convex lens for violet and red light respectively and FVand FR are the focal lengths of concave lens for ...
Hint:When a concave lens and a convex lens of the same focal length are in contact, then the power of the lens combination will be zero and its focal length will be infinite. Therefore, the combination behaves as a plane glass plate. ...
For converging lenses (convex lenses), which are thicker in the center, the focal length is considered positive. For diverging lenses (concave lenses), which are thinner in the center, the focal length is considered negative. The focal length of a lens is a crucial parameter that determines ...

Focal length = the distance from the subject to the lens + the distance from the lens to the camera sensor You also need to understand if your lens is concave or convex to determine focal length. A convex lens (also known as a converging lens) and a concave lens (also called a divergi...
