NCERT Solutions For Class 10 Science Chapter 10 – Light Reflection And Refraction
Have you ever wondered what makes things visible to us? The answer to the question is light. During the day, it is sunlight that helps us see objects. When light falls on an object, it reflects it. This reflected ray when received by our eyes helps us see things. There are numerous wonderful phenomena that are associated with light such as the formation of the rainbow, of stars and many more. In chapter 10 Light Reflection and Refraction of class 10 Science, let us study the phenomena of refraction and reflection using straight-line propagation of light. We shall also try to understand the reflection of light by spherical mirrors in this chapter.

Frequently Asked Questions on Light Reflection and Refraction
Define the principal focus of a concave mirror ?
Light rays that are parallel to the principal axis of a concave mirror converge at a specific point on its principal axis after reflecting from the mirror. This point is called the principal focus of the concave mirror.
Name the mirror that can give an erect and enlarged image of an object ?
The mirror that can give an erect and enlarged image of an object is Concave Mirror.
Why do we prefer a convex mirror as a rear-view mirror in vehicles ?
Convex mirror is preferred as a rear-view mirror in cars and vehicles as it gives a wider field of view, which helps the driver to see most of the traffic behind him. Convex mirrors always form an erect, virtual, and diminished image of the objects placed in front of it.
Define 1 dioptre of power of a lens ?
Dioptre is the SI unit of power of lens is denoted by the letter D. 1 dioptre can be defined as the power of a lens of focal length 1 metre.
The magnification produced by a plane mirror is +1. What does this mean?
The positive sign means image formed by a plane mirror is virtual and erect. Since the magnification is 1 it means that the size of the image is equal to the size of the object.
