This year the pattern and syllabus have gone some changes this year.
CHANGES IN THE PATTERN OF PAPER
The paper will have fewer questions this year. Number of questions will be 26 instead of 29 last year. There will be more weight given to application based questions in the examination. The breakdown of the questions is:

CHANGES IN THE PATTERN OF PAPER
The paper will have fewer questions this year. Number of questions will be 26 instead of 29 last year. There will be more weight given to application based questions in the examination. The breakdown of the questions is:
- Five one mark questions
- Five two marks questions
- Twelve three marks questions
- One four marks Value based question
- Three five marks questions.
CHANGES IN THE PHYSICS SYLLABUS
New Additions
- Addition supplementary material has been issued covering Internet, Mobile Telephony and GPS basics.
- Basic Idea about FM and difference between AM and FM.
Deletions
- Van de Graff Generator
- Human Eye and defects
- Production and detection of AM waves
- Transistor use as an oscillator and as a switch
But again I will advice just to read these deleted topics also as still they might ask questions from them. These deleted topics have been cross checked with last year syllabus but still I fear that questions may come as even the latest reading material issued by KVs also have questions on them
Where do we find the supplementary material for difference between am and fm?
ReplyDeleteThe advantages of AM radio - it is relatively easy to detect with simple equipment, even if the signal is not very strong. The other advantage is that it has a narrower bandwidth than FM, and wider coverage compared with FM radio.
DeleteThe major disadvantage of AM is that the signal is affected by electrical storms and other radio frequency interference.
A distinct advantage that FM has over AM is that FM radio has better sound quality than AM radio. The disadvantage of FM signal is that it is more local and cannot be transmitted over long distance. Thus, it may take more FM radio stations to cover a large area. Moreover, the presence of tall buildings or land masses may limit the coverage and quality of FM. Thirdly, FM requires a fairly more complicated receiver and transmitter than an AM signal does.
