Jyothi Samanthula. Sonal Gupta. Class 8. Shreyas Choudhary. Shruti Gupta. Convex mirrors are used as rear-view mirrors in vehicles. To see down to her foot F she only needs section BC.

Principal Focus: It is a point on the principal axis where all light rays which are parallel to principal axis either converge or appear to diverge from, after refraction.

Light pdf of reflection

A beam of light parallel to principal axis either gets converged or diverged after refraction by a lens. Some lenses converge the beam of light to a small extent and some lenses converge it to a large extent. This ability of lens to converge or diverge a beam of light is known as the power of lens. Si unit of power of lens is dioptre: One dioptre is the power of a lens whose focal length is 1 m. If two or more lenses are placed together to form a combined lens then the power of this combined lens is equal to the sum of the powers of individual lenses.

There are two types of spherical mirror. Focal Length: Uses of Concave Mirror: Uses of Convex Mirror: Mirror Formula: Laws of Refraction: The Refractive Index: This can be expressed in an equation form as Refraction by spherical lenses: Terms related to a lens Optical Centre of Lens: It is the centre of the lens through which light can pass without any deviation Principal Axis: Lens formula: Power of a lens: Power of a combination of two or more lenses: Class 6.

Two of these rays are shown here. Since the triangles share the common side BC.

Start with a mirror which is exactly her height. To see down to her foot F she only needs section BC. The person sees three images of herself. Image 2 is a single reflection image from Mirror 2. Image 1 is a single reflection image from Mirror 1.

Why are there three. Image 3 is a double reflection image from Mirrors 1 and 2.

The principal axis of the mirror is a straight line drawn through the center of curvature C and the midpoint of the mirror. If the outside surface is polished. The law of reflection applies. R is the radius of curvature of the mirror. The focal length f is the distance between the focal point and the mirror.

From CAB.

Reflection of Light | Lens (Optics) | Mirror

Rays that are far from the principal axis do not converge to a single point. The fact that a spherical mirror does not bring all parallel rays to a single point is known as spherical abberation.

Spherical abberation can be minimized by using a mirror whose height is small compared with the radius of curvature. This ray is initially parallel to the principal axis and passes through the focal point.

This ray initially passes through the focal point. This ray travels along a line that passes through the center and so reflects back on itself. If the object is placed at a distance greater than C from the mirror. A real image is one where light is actually passing through the image it can be projected onto a screen. If the direction of a light ray is reversed.

The principle of reversibility. The image is virtual.


Ray 2 heads towards the focal point. Ray 3 travels toward the center of curvature and reflects back on itself. Ray 1 is initially parallel to the principal axis and appears to originate from the focal point. Reflection of Light PDF. Flag for inappropriate content. Related titles.
