Why does parallel light focus on the focal plan when enters a thin lens at an angle θ?
How to proof that mathematically?

The focal plan of parallel light is the point at which a beam of parallel light rays converge after passing through a thin lens. This point is also known as the focal point or focal length of the lens.
The focal plan of parallel light is determined by the curvature of the lens and the refractive index of the material it is made of. The greater the curvature and refractive index, the shorter the focal length will be.
Understanding the focal plan of parallel light is important in various fields such as optics, photography, and astronomy. It allows us to accurately predict where a parallel beam of light will converge and how it will be affected by a thin lens.
Yes, the focal plan of parallel light can be altered by changing the properties of the lens such as its curvature or refractive index. This can be done by using different materials or shapes for the lens.
The focal plan of parallel light is the point where a beam of parallel light rays converge, while the focal plan of diverging light is the point where a beam of diverging light rays appear to originate from when passing through a lens. They are essentially opposite concepts.
