    The radius of curvature of the lens is = 8cm

    Calculation of radius of curvature

    The radius of curvature is defined as the radius of the circle that is made by a spherical mirror or lens.
    The focal length is defined as the distance between the point of convergence of your lens and the sensor
    The refractive index is the measure of bending of a light ray when passing from one medium to another.
    The relationship between focal length and radius of curvature is that R=2f
    Where R = radius of curvature
    f= Focal length
    Therefore, radius of curvature = 2×4 =8cm
