Rays parallel to the principal axis

WebMar 30, 2024 · First, we draw a ray parallel to principal axis. So, it appears to pass through focus after reflection. We draw another ray which passes through Center of Curvature. So, the ray will go back along the same path after reflection. Where both reflected rays meet is point A'. And the image formed is A'B'. WebDec 20, 2024 · The point at which a light ray, initially parallel to the principal axis intersects the principal axis is $\textbf{defined}$ to be the focus. As the point of reflection approached the center of the lens, the focal length converges to half of radius of the mirror.

WebApr 2, 2024 · Let a ray parallel to the principal axis PQ meet the mirror at A as shown in the figure. After reflection from the surface it meets at B. After reflection from B it emerges parallel to the principal axis. It is given that $\theta $ is the angle made by the incident ray with the centre of curvature. WebNov 24, 2024 · CALCULATION: Given that ray comes parallel to the principal axis means it comes from infinity. u = ∞. Mirror formula: 1 f = 1 u + 1 v. 1 f = 1 ∞ + 1 v. 1 f = 0 + 1 v. f = v. So the image will be at focus F or the ray will deviate in such a way that when projected backward passes through the focus.
