Lakhmir Singh Class 10 Physics Solution

Chapter 1 – Electricity

We all know how important electricity is. Electricity is one of the important sources of energy in modern times. We use electricity in our homes, in industries and in transportation. In this chapter, concepts such as electric potential, electric current, electric power and heating effects of electric current are discussed. After an explanation of every concept solved examples are given so that students can understand the concepts more easily.

Following is the table explaining the number of questions that are present in Chapter 1:

Chapter 2 – Magnetic Effect of Electric Current

Chapter 2 magnetic effect of electric current explains how electric current can be used in the production of the magnetic field. The term magnetic effect of electric current is a way of explaining electric current flowing through a wire that can produce a magnetic field around it. The simple way to explain this is, electric current can produce magnetism. The concepts such as magnetic field, magnetic field lines, properties of the magnetic field, electromagnetism, the difference between a bar magnet and electromagnet and other concepts such as what is a motor and what is a generator are covered in the chapter.

Chapter 3 – Sources of Energy

Every day we consume energy in different forms. Did you ever think from where we obtain this energy? Energy is obtained by burning fuels such as wood, LPG, kerosene, coal etc. There are different types and forms of energy. A source of energy is one which provides an adequate amount of energy in a convenient form over a long period of time. Any source of energy can be divided into two categories and they are:

• Renewable source of energy
• Non-renewable source of energy

Non-renewable sources of energy include fossil fuels such as coal, petroleum, and natural gas. It is defined as a source of energy which cannot be replaced when exhausted. While a renewable source of energy is defined as a source of energy which is present in nature and is inexhaustible. Wind energy and Solar Energy are the two examples of renewable sources of energy.

Chapter 4 – Reflection of Light

Chapter 4 speaks about what light is and how the reflection of light takes place. As we know light is a form of energy. Light helps us in seeing the objects. This takes place when the light is either coming from the object or getting reflected from the object. Concepts such as plane mirror, convex mirror, concave mirror, and reflection from these mirrors are covered in this chapter.

Chapter 5 – Refraction of Light

In the previous chapter, we learnt that light always travels in a straight path. This statement is true as long as the light rays are travelling in the same medium and the density of the medium is the same throughout. What happens to the light ray when the medium is changed? when the medium changes, the light rays won’t travel in the straight line. The change in direction of light when it passes from one medium to another is known as refraction of light.

Concepts such as laws of refraction, sign convention for lenses and refraction through lenses are covered in this chapter. Following is the table explaining the number of questions that are present in Chapter 5:

Chapter 6- The Human Eye And The Colourful World

The human eye works on the principle of refraction of light through a natural convex lens which is made up of transparent living material which enables humans to see things around them. The main parts of the human eye are cornea, iris, pupil, ciliary muscles, eye lens, retina, and optic nerve. In Chapter 6 students will learn the working and construction of the human eye. Also, the concept such as refraction of light through glass prism scattering of light by the atmosphere and atmospheric refraction.
