On April 21st, 2022, CBSE released a reduced syllabus for classes 9 to 12 of the 2022-23 academic session.

After so many changes in the last 2 to 3 years, CBSE has finalised a reduced syllabus for Class 10 teachers and students to follow. However, the term-based examination pattern will NOT BE FOLLOWED in 2022-23.

We, at Educart, were prompt about it and have updated the changes in all the subjects for you. Here, you can find:

- PDF download links to the latest
**reduced**Class 12 Physics Syllabus for 2022-23 academic session; and - simple analysis of all the
**deleted topics/ chapters**to be followed this year.

With all this information in hand, both teachers and students will have a defined structure to begin the learning process on time and efficiently.

We have also provided the syllabus for the 2020-21 session that was previously restored so that you can compare the deleted and added topics.

**2020-21 Reduced Syllabus**

**PRACTICALS**

The record to be submitted by the students at the time of their annual examination has to include:

- Record of at least 8 Experiments [with 4 from each section], to be performed by the students.
- Record of at least 6 Activities [with 3 each from section A and section B], to be performed by the students.
- The Report of the project carried out by the students.

**SECTION - A**

**Experiments**

- To determine resistivity of two / three wires by plotting a graph for potential difference versus current.
- To find resistance of a given wire / standard resistor using a metre bridge.
- To verify the laws of combination (series) of resistances using a metre bridge.

OR

To verify the laws of combination (parallel) of resistances using a metre bridge.

- To determine resistance of a galvanometer by half-deflection method and to find its figure of merit.
- To convert the given galvanometer (of known resistance and figure of merit) into a voltmeter of desired range and to verify the same.

OR

To convert the given galvanometer (of known resistance and figure of merit) into an ammeter of desired range and to verify the same.

- To find the frequency of AC mains with a sonometer.

**Activities**

- To measure the resistance and impedance of an inductor with or without iron core.
- To measure resistance, voltage (AC/DC), current (AC) and check continuity of a given circuit using a multimeter.
- To assemble a household circuit comprising three bulbs, three (on/off) switches, a fuse and a power source.
- To assemble the components of a given electrical circuit.
- To study the variation in potential drop with length of a wire for a steady current.
- To draw the diagram of a given open circuit comprising at least a battery, resistor/rheostat, key, ammeter and voltmeter. Mark the components that are not connected in proper order and correct the circuit and also the circuit diagram.

**SECTION - B**

**Experiments**

- To find the value of v for different values of u in case of a concave mirror and to find the focal length.
- To find the focal length of a convex mirror, using a convex lens.
- To find the focal length of a convex lens by plotting graphs between u and v or between 1/u and 1/v.
- To find the focal length of a concave lens, using a convex lens.

- To determine the refractive index of a glass slab using a travelling microscope.
- To find the refractive index of a liquid using a convex lens and plane mirror.
- To find the refractive index of a liquid using a concave mirror and a plane mirror.
- To draw the I-V characteristic curve for a p-n junction diode in forward and reverse bias.

**Activities**

- To identify a diode, an LED, a resistor and a capacitor from a mixed collection of such items.
- Use of a multimeter to see the unidirectional flow of current in case of a diode and an LED and check whether a given electronic component (e.g., diode) is in working order.
- To study the effect of intensity of light (by varying distance of the source) on an LDR.
- To observe refraction and lateral deviation of a beam of light incident obliquely on a glass slab.
- To observe diffraction of light due to a thin slit.
- To study the nature and size of the image formed by a (i) convex lens, or (ii) concave mirror, on a screen by using a candle and a screen (for different distances of the candle from the lens/mirror).
- To obtain a lens combination with the specified focal length by using two lenses from the given set of lenses.On April 21st, 2022, CBSE released a reduced syllabus for classes 9 to 12 of the 2022-23 academic session.
