Light : Reflection and Refraction

In this chapter we shall discuss about the important phenomena of light i.e. reflection and refraction of light in detail. These basic concepts will help us in study of some of optical phenomena in nature and their application in real life situations. The important topics to be discussed in this chapter are Nature of light, Laws of reflection of light; Reflection of light from plane and curved surfaces; Center and radius of curvature, pole, principal axis, principal focus and focal length of spherical mirrors; Relation b/w radius of curvature and focal length of spherical mirrors; Rules of image formation in spherical mirrors; Uses of spherical mirrors; Refraction of light, its causes and effects; laws of refraction; Refraction of light through a parallel–sided glass slab and by spherical lenses; Optical center, principal focus and focal length of spherical lenses; Image formation by spherical lenses; Uses of spherical lenses; Power of a lens and their combination. Human Eye and the Colourful World

In this chapter we shall discuss about the Construction and working of eye; Function of Iris and pupil; Light sensitive cells in human eye; Range of vision of normal human eye; Defects of vision such as myopia , hypermetropia , presbyopia, cataract and their correction using lenses; Refraction of light through a glass prism; Dispersion of light; Atmospheric refraction and its effects; Scattering of light, its properties and effects.

Electricity

As we all know electricity is an important source of energy in the modern times and is used in our homes, in industry and in transport, one must have a basic understanding of electricity. The important topics to be discussed in this chapter are Electric charges and its types; SI unit of electric charge i.e coulomb; Conductors and insulators; Electric potential and potential difference between two points; Measurement of potential difference using voltmeter; Electric current and its measurement using ammeter; Electrical circuit diagrams and the symbols used for electrical components; Ohm’s law that defines the relationship between potential difference and current and its verification; Resistances and the factors affecting it; Combination of resistors in series and parallel; Electric power and its calculation; Commercial unit of electrical energy i..e. kwh and its use to calculate the cost of electrical energy consumed; Heating effect of electric current and its applications.

Magnetic Effects of Electric Current

In this chapter we shall learn about Magnetic effects of electric current i.e. the magnetic field produced around a wire carrying electric current. The important topics to be discussed in this chapter are Magnetic field lines which describes the magnetic field properties of these magnetic field lines, and how to plot these lines in case of a bar magnet; Magnetic field of earth; Magnetic effect of current demonstrated through an experiment; Magnetic field pattern produced due to a straight current carrying conductor; Right hand thumb rule and Maxwell’s cockscrew rule which are used to find the direction of magnetic field produced; Magnetic field due to a circular wire carrying current and a current carrying solenoid; Clock face rule which is used to determine direction of current in circular wire; Electromagnets; Demonstration of force acting on a current carrying conductor placed in a magnetic field through an experiment and to find direction of force using Fleming’s left hand rule ; Principle, working and construction of electric motor; Electromagnetic induction i.e. electricity from magnetism; Principle, construction, working and types of generator, Domestic electric circuits; Hazards of electricity and precautions to be taken while using it. Sources of Energy

Source of energy is the one which can provides adequate amount of energy in a convenient form over a long period of time. Thus, we are going to learn about various sources of energy that are available to us in this chapter.

The important topics to be discussed are Types of sources of energy; Fuels and its calorific value; Characteristics of an ideal fuel; Conventional sources of energy; Fossil fuels and their formation; Coal, petroleum and natural gas; Ways to control pollution caused by fossil fuels; Effects of industrialization; Non–conventional sources of energy i.e. hydroelectric energy, wind energy, solar energy, biomass energy, Tidal energy, geothermal energy, nuclear energy and their applications; Einstein’s mass–energy relation and Environmental consequences of increasing demand for energy.

Our Environment

Environment is the surrounding or condition in which we live. All of you must have heard of environment, but did you ever thought of the harms we are causing to it, we shall discuss that here in the chapter. The important topics to be discussed in this chapter are Impact of human beings on environment; Components of ecosystem; Food chains and webs; Ozone layer depletion and garbage management.

Management of Natural Resources

Natural resources are those resources that are made available to us by nature, so here in this chapter we shall learn about the proper management of these resources. The important topics to be discussed in this chapter are Concept of Reduce, Reuse and Recycle; Need to manage resources; Forest and wildlife; Water management through dams; Water harvesting; Coal and Petroleum.

All the above mentioned topics are described in an interactive and efficient manner, as per the latest CBSE syllabus of Class X, so that the students could easily understand them.
