FAQs on Previous Year Class 12 CBSE Physics Paper 2018 PDF
1. Where can I find the Previous Year Physics Question Paper for CBSE Class 12 - 2018 - Free PDF Download?
You can easily find the Previous Year Physics Question Paper for CBSE Class 12 - 2018 - Free PDF Download on Vedantu. We provide on-point notes and previous year papers, these notes and papers can be helpful to you in your school exams as well as CBSE board exams. Notes work best when you make them yourself.
2. How do I prepare for Chapters of CBSE Class 12 Physics that include formulas and numerical?
Let practice be your friend. Solve as many numericals as you can. Always make sure you are clear about the numerical given at the end of every chapter. NCERT books have a few exercises at the back of every chapter. These exercises are most important. Solve the numericals given in them. To memorize formulas, you must be clear about how they are derived. Practice derivation of various formulas especially from chapters like wave Optics, magnetism, and electric charge. Get the previous year question papers of Physics for Vedantu and solve them for further practice.
3. Why should you first prepare NCERT Class 12 Physics book?
Before moving on to solving, referring, and reading other books for your class 12, you should first concentrate on the NCERT textbook. The NCERT textbook aims to give you a clear understanding of a complex subject like Physics. The NCERT book can also be helpful for those who have to give entrance exams such as JEE and NEET. Jumping directly to reference books will only lead to unwanted confusion. Reference books are meant for practice after your basics are entirely clear.
4. What do you mean by the Dual nature of radiation as taught in class 12 Physics?
Radiation has two different properties. It behaves like a wave as well as a particle. The dual nature of radiation refers to two natures of radiation, one is the ‘wave nature and the other is the ‘particle nature.’ Light shows an interference pattern, this can only be possible if it has a wave nature. This can be observed in Young's Double Slit Experiment. The particle nature of radiation can be observed when we direct light on a cathode with a frequency exceeding the threshold frequency. The cathode ejects an electron, this leads to photoelectric current in the circuit. Both the experiments prove the dual nature of radiation.
5. What is the application of Polarization that is discussed in CBSE Class 12 - 2018 - Free PDF Download?
The application of polarization is as follows:
3-D movies use the phenomenon of polarization. We can see 3-D movies using a 2-D frame with the help of polarization.
Polarization is also used to study natural calamities like earthquakes.
In organic chemistry, to find out the chirality of organic compound techniques working on the principles of polarization is used.
In sunglasses, polarization is used to reduce the glare of the sunlight.
A method of analysis in chemistry is known as Infrared spectroscopy using polarization.
