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. WebA concave lens refracts parallel rays in such a way that they are bent away from the axis of the lens. For this reason, a concave lens is referred to as a diverging lens. A) Consider the following diagrams, where F represents the focal point of a concave lens. WebFocus is a point on the axis of symmetry such that if the surface was a mirror, the light rays incident on the surface from a light source placed at the focal point, would lead to the reflection of the light rays, parallel to the axis of symmetry.

WebA A ray parallel to the principal axis of the lens is refracted through the principal focus. B All rays of light refracted by the lens pass through the principal focus. C The distance between the centre of the lens and the principal focus is the focal length. D The principal focus of the lens is a point on the principal axis. WebAs a result, a lens has two primary focuses. The focal position of such a concave lens seems to be a position F 2 upon that lens's primary axis where light rays incident parallel towards the principal axis seems to diverge the following refraction by the lens. Therefore, whenever parallel light beams flow through a concave lens towards the main ...

WebA ray parallel to the x - axis is incident at a point P on a parabolic reflecting surface, and the reflected ray becomes parallel to y - axis as shown in the figure.

Having passed through the lens the rays intersect at a point $15\,cm$ from the lens on the opposite side. If the lens is removed the point where the rays meet will move $5\,cm$ closer to the lens. The focal length of the lens is

WebApr 3, 2024 · 1. When the parallel rays of light pass through a concave lens to the principal axis, it deviates from its focal point and refracts the light rays. Due to this reason, it is called the Concave or Diverging lens. An incident light ray parallel to the principal axis of a concave lens, passes through it and diverges. 2.

WebAnswer (1 of 2): The answer is heeden in centre of curvature. As we know that when a ray passes through center of curvature it falls back. It happens as it is a centre of sphere , which act as normal to circumference (concave mirror). So when a ray incident parallel to principal axis it passes ...
