Mastering Light and Lenses

Study Notes

CBSE Class 10 Science Notes Chapter 10 is about light reflection and refraction.
Reflection is the bouncing back of light into the same medium by a smooth surface.
Mirrors can be plane or spherical.
Refraction is the bending of light at the interface of two different mediums.
Lenses are a transparent refracting medium bounded by two surfaces.
There are two types of refractive index: relative and absolute.
The law of refraction states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is constant.
Special rays are used for image formation by mirrors and lenses.
Mirrors and lenses have different parameters, including focal length and magnification.
The position of the image for various positions of the object can be determined using tables.
A lens refracts light and can be convex or concave.
A lens with a higher refractive index than the lens can convert it from convex to concave.
A converging lens is thicker at the center while a diverging lens is thicker at the edges.
The optical center of a lens is the point where a ray passing through it is undeviated.
The principal axis of a lens is the line joining its two centers of curvature and passing through the optical center.
The aperture is the effective width of a lens through which refraction occurs.
The focus is the point where a beam of light moving parallel to the principal axis converges or meets.
The focal length is the distance between the focus and the optical center.
The magnification produced by a lens is the ratio of the size of the image to the size of the object.
The power of a lens is the reciprocal of its focal length and is measured in diopters.
