2: Use of multimeter to (i) identify base of transistor, (ii) distinguish between npn and pnp type transistors, (iii) see the unidirectional flow of current in case of a diode and an LED, (iv) check whether a given electronic component (e.g., diode, transistor or IC) is in working order.

3: To study effect of intensity of tight (by varying distance of the source) on an LDR.

4: To observe refraction and lateral deviation of a beam of tight incident obliquely on a glass slab.

5: To observe polarization of light using two Polaroids.

6: To observe diffraction or light due to a thin slit.

7: To study the nature and size of the image formed by a (i) convex lens, (ii) concave mirror, on a screen by using a candle and a screen (for different distances of the candle from the lens/mirror).

8: To obtain a lens combination with the specified focal length by using two lenses from the given set of lenses.

After going through CBSE Class 12 Physics Practical’s syllabus (list of experiments) and evaluation scheme, it is clear that you can score maximum marks (or full marks) if you have successfully completed the experiments assigned to you (at the time of practical exam), you have practical record (signed by your teacher), projects etc and you have performed exceptionally well in viva.

The Physics Practicals For Class 12 CBSE is given here so that students can understand the experiments in a better way.

Students are suggested to study the theory and law behind the experiment properly before performing the experiment.

Here are few quick tips:

• Thoroughly read the complete theory behind the experiment

• Understand Graph: Graphs, important part of Physics practical exams, students need to practice them

• Revise Practical notes (including Theory Notes)

• Imagine the diagram of the experiment & draw it roughly

• Experiments are develop to prove the Physics principle. Therefore, remember the basic principles behind performing the particular experiment.

• Methodology and Principle are the frequently asked questions during viva.

• Don’t be nervous at the time of experiment & write the important steps before starting the practical (you can also draw a flowchart)

• In case of any doubt, consult with the teacher or lab attendant.
