FAQs on Bihar Board (BSEB) Class 12 Physics Latest Syllabus 2023-24
1. Apart from conducting board exams, what programs does BSEB organizes?
Besides conducting the Board exams, Bihar Board also organizes the following programs:
Diploma in Physical Education (Phy. Ed).
Certificate in Physical Education.
Teacher Training Program and these programs are not yearly based.
2. If two thin lenses of powers 6 D and 4 D are aligned at a distance 15 cm apart, find the power of the combination of lenses.
P1 = 6 D, P2 = 4 D, d = 15 cm or 0.15 m
The formula for the power of combination of thin lenses is:
P1 + P2 - dP1P2
= 6 + 4 - 0.15 * 6 * 4
PowerCOMBINATION OF LENSES = 10 - 3.6 = 6.4 D
3. Define the term ‘Modulation.’ Mention its types.
In electronics & Communication, modulation is the procedure of converting data/message into radio waves by adding information to an electronic/optical carrier signal optimized for transmission.
The following are the types of modulation:
Amplitude Modulation
Frequency Modulation
Phase Modulation
4. Define the term Shunt. Write its two uses.
A low resistance wire that is connected in parallel with the circuit is called a shunt. Its uses are:
Protecting the coil of a galvanometer from high currents.
For transforming a Galvanometer into an Ammeter.
