Length is measured using Vernier callipers and micrometre screw gauges. Increasing accuracy is achieved by decreasing the least-count (LC) of Vernier callipers and screw gauges. The concept of zero error is introduced briefly, with no numerical problems on callipers and screw gauges.
3. The study of a simple pendulum covers time period, frequency, and the graph of length (l) versus T^2 only. The slope of the graph is discussed, and the formula T=2.π. √ l/g is presented without derivation. Only simple numerical problems are included in the syllabus.

ICSE Class 9 Physics Chapter 6 - Light

1. Reflection of light involves how light bounces off surfaces. Images are created by two mirrors, one parallel and one perpendicular. Rules for reflection and proof through experiments are discussed. We look at images formed in both parallel and perpendicular mirrors and explore the practical uses of flat mirrors.
2. Spherical mirrors, we study the images they create. Concave and convex mirrors have specific uses, and simple ray diagrams help understand them. Key terms like centre, radius of curvature, pole, principal axis, focus, and focal length are introduced. We use ray diagrams to find image positions for objects along the principal axis, exploring characteristics of the images. The formula f = R/2 is mentioned without proving it. Sign conventions and solving numerical problems with mirror formulas are covered, but derivations are skipped. The practical applications of spherical mirrors are also discussed. No need for scale drawings or graphical representations in this chapter.

ICSE Class 9 Physics Chapter 7 - Sound

1. Characteristics of Sound Waves: Sound waves require a medium to travel through. They move at different speeds in various mediums and can be compared to the speed of light. The terms related to sound propagation include frequency (f), wavelength (λ), and velocity (V), with the relationship V = fλ. Simple numerical problems can help understand these concepts. Factors Affecting Sound Speed; Various factors influence the speed of sound, and it's interesting to compare it with the speed of light. The significant difference in these speeds in the air has consequences, such as the occurrence of thunder and lightning.
2. Sound Frequencies: Sound waves can be categorised into infrasonic, sonic, and ultrasonic frequencies, each with its applications. Exploring elementary ideas and basic applications helps in understanding these concepts. It's important to distinguish between ultrasonic and supersonic frequencies.

ICSE Class 9 Physics Chapter 8 - Electricity and Magnetism

1. Creating a basic electric circuit involves using a battery and a light bulb to teach about electric current, potential difference, insulators, conductors, closed and open circuits, and the direction of current (both electron flow and conventional). The introduction to current electricity includes a brief overview of direct current sources such as cells and accumulators, without going into construction, working, or equations. The concept of electric current as the flow rate of electric charge is explored, along with the use of symbols in circuit diagrams. Current detection using a Galvanometer or ammeter is mentioned, but details about how the metres work are not included. An electric circuit is qualitatively explained using a cell, key, and resistance components, touching on the idea of work done in transferring charge through a conductor wire, represented by the potential difference equation V = W/q. No derivation of the formula is provided, only simple numerical problems.

The sequence of induction preceding attraction, properties of magnetic field lines, and evidence of Earth's magnetic field existence using a magnetic compass are explained. The contrast between the uniform magnetic field of the Earth and the nonuniform field of a bar magnet placed along the magnetic north-south axis is highlighted, along with the concept of a neutral point and properties of magnetic field lines.
