Question

summary of chapter light of 10th physics

Answer 1

-Light seems to travel in straight lines.
-Mirrors and lenses form images of objects.Images can be real or virtual.
-The reflecting surfaces obey the laws of reflection.
-New Cartesian Sign Conventions are followed for spherical mirrors and lenses.
-Mirror formula gives the relationship between the object&distance,image&distance, and focal length of a spherical mirror.
-The magnification produced by a spherical mirror is the ratio of the light of the image to the height of the object.
-Light ray traveling obliquely from a denser medium to a rarer medium bends away from the normal.
-A light ray bends towards the normal when it travels obliquely from a rarer to a denser medium.
-The refractive index of a transparent medium is the ratio of the speed of light in vacuum to that in the medium.

Answer 2

Answer:

CBSE Class 10 Science Notes Chapter 10 Light Reflection and Refraction. ... Mirror: The surface which can reflect the light is a mirror. Plane Mirror: If the reflecting surface is a plane then the mirror is plane. Spherical Mirror: If the reflecting surface is part of the hollow sphere then the mirror is a spherical mirror
