These questions are designed to test students' understanding of modern physics concepts and their ability to apply these concepts to real-world problems. Students should be able to answer these questions using their knowledge of modern physics and their practical skills. These may be very helpful for those going to face skill test based on practical knowledge in interview of Junior Intelligence Officer (JIO) in intelligence bureau (IB) ministry of Home Affairs.

Here is an example of a more specific practical question:
How would you use a Wilson cloud chamber to observe the tracks of charged particles?
To answer this question, students would need to know the principles of operation of a Wilson cloud chamber, as well as the properties of charged particles. They would also need to be able to design and carry out an experiment involving the use of a Wilson cloud chamber.
These are just a few examples, and there are many other practical skill-based questions that can be asked from physics students. The specific questions that are asked will depend on the level of the students and the topics that they have been covering in class. These are very important questions for the skill test of Junior Intelligence Officer (JIO) post in Intelligence Bureau (IB) Ministry of Home Affair.
In addition to the above questions, students can also be asked to design and carry out their own experiments to investigate physics concepts. This is a great way for students to develop their practical skills and to learn how to apply the principles of physics to real-world problems.

Here is an example of a more specific practical question in physics experiment based:
How would you measure the speed of light using a rotating mirror apparatus?
This question is more specific than the previous ones, as it requires students to know about a specific experimental setup called a rotating mirror apparatus. Students would need to know the design and principles of operation of this apparatus, as well as the basic concepts of optics and electromagnetism, in order to answer this question.
To answer this question, students would need to design and carry out an experiment using a rotating mirror apparatus. The experiment would involve measuring the distance traveled by a light beam between two mirrors, as well as the time it takes for the light beam to travel between the mirrors. Students would then be able to calculate the speed of light using these measurements.

Here is another example:

How would you use a Michelson interferometer to measure the wavelength of light?
This question is also more specific than the previous ones, as it requires students to know about a specific experimental setup called a Michelson interferometer. Students would need to know the design and principles of operation of this apparatus, as well as the basic concepts of optics and interference, in order to answer this question.
To answer this question, students would need to design and carry out an experiment using a Michelson interferometer. The experiment would involve measuring the number of interference fringes produced by the interferometer when a light beam of a known wavelength is passed through it. Students would then be able to calculate the wavelength of the light beam using this measurement.
