13.1 What makes Things Visible: As discussed in the NCERT solutions for class 8 science light, Light and matter interact to create visible objects. There are several reasons why and how objects become visible, which are discussed in this section.

13.2 Laws of Reflection:  As discussed in the NCERT solutions for class 8 science light, The laws of reflection refer to the way light behaves when it hits a smooth, reflecting surface, like a mirror. The laws of reflection govern how light is reflected and where it travels.

13.3 Regular and Diffused Reflection:  As discussed in the NCERT solutions for class 8 science light, Light can bounce off different surfaces in different ways, so different patterns of reflection can happen. Regular reflection is one type of reflection, while diffused reflection is a different type of reflection that happens under different conditions.

13.4 Reflected Light Can be Reflected Again: As discussed in class 8 science chapter 13 light ncert solutions, Reflected light can be refracted multiple times, and this phenomenon is referred to as multiple reflection. Multiple reflections refer to the fact that light undergoes multiple successive refractions off multiple different surfaces or mirrors, each of which alters the direction of light. The final direction of light is determined by the angle at which the reflected light strikes each of the surfaces.

13.5 Multiple Images: As discussed in class 8 science chapter 13 light ncert solutions, The phenomenon of multiple images, also referred to as multiple reflections or “successive reflections,” occurs when light passes through a series of refractions between two or more reflective surfaces or mirrors. The result of this process is the generation of multiple images of the same object. The amount of images generated is dependent on the configuration and orientation of the reflective surfaces or mirrors used.

13.6 Sunlight- white or coloured: As discussed in class 8 science chapter 13 light ncert solutions, White light dispersion refers to the fact that sunlight is made up of a spectrum of colours, not just white light or colored light. White light dispersion is caused by the way in which sunlight interacts with the environment.

13.7 What is inside Our Eyes?: As discussed in class 8 science chapter 13 light ncert solutions, The eye is a multifaceted organ responsible for visual perception and processing. It is composed of a number of components, each of which has its specific function.

13.8 Care of the Eyes: As discussed in ncert solutions class 8th science chapter 13, Caring for your eyes is important for keeping your eyes healthy and preventing vision issues. Here are some things you can do to take care of your eyes:

  • Regular eye exams: Visit your optometrist or eye doctor for regular eye exams. These exams can help your doctor identify and address any vision problems you may not have even if you don’t have any symptoms.

  • Protect your eyes with protective eyewear: Wear protective eyewear when engaging in activities that could put your eyes at risk, such as playing sports, working with wood or using power tools.

13.9 Visually Impaired Persons Can Read and Write: As discussed in ncert solutions class 8th science chapter 13, There are a variety of ways for visually impaired people to read and write, as well as assistive technologies that make it easier for them to communicate in written form. Each method and assistive technology is designed to meet the needs of different visual impairments and personal preferences.

13.10 What is the Braille System?: As discussed in class 8 science ch 13 light ncert solutions, The Braille system is taught to visually impaired people by starting with letters, followed by special characters and letter combinations. Learning methods depend on touch-recognition. Each character must be remembered. Braille text can be written by hand or by machine. Typewriter devices and printing machines have been developed.

Key Features of Class 8 Science Chapter 13

  • Light reflects from all types of surfaces. 

  • Regular reflection occurs when light is encountered on smooth, smooth and regular surfaces. 

  • Diffused and irregular reflections occur when light is encountered from rough surfaces. There are two laws of reflection: (a) the angle of incidence equals the angle of reflection; and (b) an incident ray, a reflected ray, and the normal drawn at the point where the light is encountered to the reflecting surface lie in one plane. 

  • An image formed in a mirror that is inclined to one side undergoes a lateral inversion. Multiple reflections give rise to beautiful patterns in a kaleidoscope. 

  • Sunlight, also known as white light, is made up of seven different colours. Dispersing light into its component colours is called dispersion. 

  • The eye is made up of four parts: the cornea, the iris, the pupil, the lens, the retina and the optic nerve. 

  • A normal eye is able to see near and far objects clearly. A visually impaired person is able to read and write using Braille. 

  • They develop their other senses more sharply to better interact with their environment.
