NCERT Solutions for Class 8 Science Chapter 16 Light in Hindi
The NCERT Solutions For Class 8 Science Chapter 16 In Hindi also covers the following topics in extensive detail:
- How Do Things Become Visible?
- Reflection Laws
- Diffused and Regular Reflection
- Light That Is Reflected Can Be Reflected Again
- Many Pictures
- White or coloured sunrays
- What resides within our eyes?
- Eyesight Maintenance
- People with visual impairments can read and write
- What exactly is the Braille system?
The aforementioned topics are discussed below to provide students a fair idea of all the topics addressed in Extramarks’ NCERT Solutions For Class 8 Science Chapter 16 In Hindi:
The Laws of Reflection:
- The angle of incidence and the angle of reflection are always equal. It is the reflection law.
- The normal at the point of incidence, the incident ray, and the reflected ray are all located in the same plane. This is yet another reflectional law.
- Light is typically reflected in a different direction when it hits a mirror or any other object. The incident ray is the light ray that makes contact with any surface. The reflected ray is the one that returns from the surface after reflection.
- The normal to the reflecting surface is the line that forms a 90° angle with the line denoting the mirror or surface of the item at the location where the incident ray strikes the mirror.
- The angle of incidence (∠i), is the angle formed by the incident ray and the normal. The reflection angle (∠r) is the angle formed by the normal beam and the reflected ray.
The term “lateral inversion” refers to the mirror image when the left of the object appears on the right and the right appears on the left.
Types of Reflection:
The reflection is referred to as a dispersed or uneven reflection when none of the parallel rays reflected off a planar surface are parallel. Diffused reflection is not a result of the Law of Reflection failing; rather, it is a result of flaws in the reflecting surface.
Regular reflection is the reflection off of a smooth surface, such as a mirror. Regular reflections result in images.
