Physics is a fundamental subject in science that is concerned with the study of matter, energy, and their interactions. In order to understand the concepts of physics, it is essential to have a hands-on approach. Practical experiments are a great way to demonstrate the laws of physics and apply them in real-world situations. CBSE Class 11 Physics Practical Syllabus is designed to give students a practical understanding of the subject and develop their scientific skills.

Overview of CBSE Class 11 Physics Practical Syllabus:

The CBSE Class 11 Physics Practical Syllabus consists of two sections – Section A and Section B. Section A consists of a total of 30 marks, while Section B consists of a total of 20 marks. The practical examination is conducted for a total of 30 marks.

Section A:

Section A of the CBSE Class 11 Physics Practical Syllabus comprises two experiments. The experiments in this section aim to develop the practical skills of students and help them understand the basic concepts of physics.

The experiments in this section are as follows:

To determine the value of the acceleration due to gravity using a simple pendulum:

This experiment involves measuring the time period of a simple pendulum and using it to determine the value of the acceleration due to gravity. The experiment helps students understand the concept of simple harmonic motion and the factors that affect the time period of a pendulum.

To study the relationship between the force of limiting friction and the normal reaction and to find the coefficient of friction between a block and a horizontal surface:

This experiment involves finding the coefficient of friction between a block and a horizontal surface by measuring the force of limiting friction and the normal reaction. The experiment helps students understand the concept of friction and its role in daily life.

Section B:

Section B of the CBSE Class 11 Physics Practical Syllabus comprises seven experiments. The experiments in this section aim to develop the experimental skills of students and help them understand the advanced concepts of physics. The experiments in this section are as follows:

To measure the resistivity of a given wire using a meter bridge and hence determine the specific resistance of its material:

This experiment involves measuring the resistivity of a given wire using a meter bridge and calculating the specific resistance of the wire. The experiment helps students understand the concept of resistivity and its applications in electrical circuits.

To verify the laws of combination of resistances using a meter bridge:

This experiment involves verifying the laws of combination of resistances using a meter bridge. The experiment helps students understand the laws of combination of resistances and their application in electrical circuits.

To find the focal length of a convex lens by plotting graphs between u and v or between

This experiment involves finding the focal length of a convex lens by plotting graphs between the object distance and image distance. The experiment helps students understand the concept of lenses and the formation of images.

To find the frequency of AC mains with a sonometer:

This experiment involves finding the frequency of AC mains using a sonometer. The experiment helps students understand the concept of sound waves and the application of sonometers in determining the frequency of sound waves.

To find the velocity of sound in air at room temperature using a resonance tube by two resonance positions:

This experiment involves finding the velocity of sound in air at room temperature using a resonance tube. The experiment helps students understand the concept of sound waves and the measurement of their velocity.

To study the variation in potential drop with length of a wire for a steady current:

This experiment involves studying the variation in potential drop with the length of a wire for a steady current. The experiment helps students understand the concept of Ohm’s law and its application in electrical circuits. Students will be required to set up a circuit with a constant current and measure the potential difference across the wire at different lengths. By plotting a graph of potential difference versus length, students can determine the resistance of the wire and verify Ohm’s law. This experiment also helps students understand the effect of wire length on resistance and the significance of the resistance in electrical circuits.

To draw the characteristic curves of a p-n junction diode in forward and reverse bias:

This experiment involves drawing the characteristic curves of a p-n junction diode in forward and reverse bias. Students will be required to set up a circuit with a diode and measure the current flowing through the diode at different voltages. By plotting a graph of current versus voltage, students can understand the behavior of the diode in forward and reverse bias. This experiment also helps students understand the application of diodes in electronic circuits.
