Light class 8th 

Introduction to Light

Light is a fascinating form of energy that lets us see the world around us. It's what makes our mornings bright and our nights less scary. The Sun is the most prominent natural source of light, warming our planet and providing energy for life. Light allows us to see objects either because they emit light (like the Sun) or because they reflect light (like the Moon and mirrors).

Reflection: How Light Bounces Back

Reflection is what happens when light hits an object and bounces back. How much light bounces back depends on the surface it hits. Smooth surfaces like mirrors reflect light the best. The ray of light that falls on the mirror is called the incident ray, and the light that bounces back is the reflected ray. At the point where light hits, called the point of incidence, a perpendicular line can be drawn. This line is known as the normal. The angles made by the incident and reflected rays with the normal are called angles of incidence and reflection.

Laws of Reflection

Reflection isn't random; it follows specific laws. The angle of incidence is always equal to the angle of reflection. Also, the incident ray, the reflected ray, and the normal all lie in the same plane. These laws help us understand how light behaves and are foundational to optical science.

Lateral Inversion: The Mirror Effect

When you look in a mirror, your image seems flipped from left to right. This is called lateral inversion. It's a curious effect and is something that is studied when learning about plane mirrors.

Regular and Diffused Reflection

In a perfect world, all reflected rays are parallel, and this is called regular reflection. This is what we see in mirrors. However, in the real world, surfaces aren't always smooth. So, light rays scatter in multiple directions, leading to diffused or irregular reflection.

Multiple Reflection: More than One Bounce

Sometimes, light doesn't just bounce once; it can bounce multiple times. This happens in devices like periscopes and kaleidoscopes. Periscopes are used in submarines to see above water, while kaleidoscopes create beautiful patterns.

Sunlight: Is it White or Colored?

Ever seen a rainbow? It's an arch of colors that shows up when sunlight is dispersed by water droplets. This tells us that sunlight is not just white; it's made up of many colors, which can be remembered by the acronym VIBGYOR (Violet, Indigo, Blue, Green, Yellow, Orange, Red).

The Human Eye: Our Window to the World

Our eyes are complex organs that capture light and send signals to our brain, allowing us to see. The front part of the eye is the cornea, and behind it is the iris, which controls the amount of light entering the eye through the pupil. The lens focuses this light onto the retina, which has sensory cells that send the image to our brain via the optic nerve.

Taking Care of Our Eyes

Good eye care includes wearing correct glasses, not staring at bright lights, and eating foods rich in Vitamin A. Always keep a good distance while reading and wash your eyes with clean water if something enters them.

Defects and Visual Impairment

Eyes can have defects that affect our vision. These can be corrected with suitable lenses. Some people have visual impairments from birth, but they can use alternative methods like Braille to read and communicate.


Understanding light and how it interacts with objects and our eyes is not just for Class 8 Chapter 13 Science or for filling out your Light Class 8 Worksheet With Answer, Light Class 8 MCQ, or Light Class 8 Extra Question Answer. It's knowledge that benefits us in daily life. Light is a fascinating subject, and understanding it can illuminate many areas of science and human experience.

Light Class 8 Worksheets with Answers

Worksheets are an excellent tool for students to revise and test their understanding of the topic. The Light Class 8 Worksheets with Answers are designed to cover multiple aspects of the topic, such as the properties of light, reflection, and refraction. These worksheets often include diagrams, multiple-choice questions, and short-answer questions. By completing these, students can gauge their readiness for exams and grasp the subject matter thoroughly.

Light Chapter of Class 8 Questions and Answers

The questions and answers for Class 8's chapter on light are carefully designed to cover all the important topics.

These questions can delve deeper into the topic, asking about real-world applications or the science behind phenomena like rainbows and mirages. Light Class 8 Extra Questions are designed to challenge students' understanding of the topic and prepare them for questions that might come in competitive exams or higher classes.


What is light?

Light is a form of energy that enables us to see objects. It is either emitted by objects like the Sun or reflected off of non-luminous objects like the Moon.

What is reflection?

Reflection is the process where light bounces back after hitting a surface. Smooth surfaces like mirrors reflect light the best.

What are the Laws of Reflection?

There are two main laws:

  1. The angle of incidence is equal to the angle of reflection.
  2. The incident ray, reflected ray, and the normal line at the point of incidence all lie in the same plane.

What is refraction?

Refraction is not typically covered in Class 8. However, it's the bending of light when it passes from one medium into another, like from air to water.

What is lateral inversion?

Lateral inversion is when an image is flipped from left to right or vice versa. This happens in plane mirrors.

What is the difference between regular and diffused reflection?

In regular reflection, all reflected rays are parallel. In diffused reflection, they scatter in different directions. Smooth surfaces provide regular reflection, while rough surfaces result in diffused reflection.

What are luminous and non-luminous objects?

Luminous objects emit their own light, like the Sun. Non-luminous objects do not emit light; they only reflect it, like the Moon or a book.

What is multiple reflection?

Multiple reflection occurs when a light ray is reflected more than once. This concept is used in devices like periscopes and kaleidoscopes.

What is the natural source of light?

The natural source of light is the Sun. It provides us with natural light during the daytime.

How do our eyes see objects?

Our eyes see objects when light emitted or reflected from those objects enters our eyes. The lens in the eye focuses this light onto the retina, where it is converted into electrical signals and sent to the brain.

What is a rainbow?

A rainbow is formed when sunlight is dispersed into its various colors after passing through water droplets in the air.

What is the blind spot in the human eye?

The blind spot is the area on the retina where the optic nerve leaves the eye. It has no light-sensitive cells, so you can't see anything that falls on it.

How can we take care of our eyes?

To care for your eyes, avoid staring at bright lights, read in good lighting, and eat a diet rich in Vitamin A. Also, wash your eyes with clean water if dust enters them.

What are some common eye defects?

Common eye defects include myopia (nearsightedness) and hyperopia (farsightedness). These can be corrected with suitable lenses.

What is Braille?

Braille is a system of raised dots that visually impaired people can use to read and write. It was developed by Louis Braille.
