Application of Concave and Convex LensesApplication of concave and convex lenses are an important tool to understand the application of concave and convex lenses. These are based on the two laws: - one is the law of refraction and other is the law of reflection. The main use of lenses can be used to be focusing the light in one point or light separated in different path.
Convex lens or lenses which bulge out from the lens is called convex. Concave or basically these lenses are depressed inside and hence are called concave. It is important to note that the line joining between the centers of the spheres is called axis of the lens. Mainly the concave and convex lens axis move through the lens center, because of the way lens is making. Lenses making may be cutting in ground to give them various shape and size.
For the application of concave and convex-lenses it is important to understand the main equation of lens which is known as Lens maker’s equation. The focal length of the lens in air can be finding the formula from the lens maker’s equation.
Now the basic notations of the words are as follows:-
P is denote as the power of lens
f is denoted as the focal length of the lens,
n is denoted as refractive index of the lens material,
R1 is denoted as the radius of curvature all kind of the lens. The surface very near to the light source,
R2 is denoted as the radius of curvature of all kind of lens surface very far from the light source,
Apart from the above applications, there are various applications as well.
