IBDP Physics Question Analysis Topic: Physics - Short Questions
Exam Questions:
1) Fill in the blank with an appropriate answer:
A compound microscope is used because a realistic simple microscope does not have _______ magnification.
2) Answer the following:
Define the term 'threshold frequency' in photoelectric emission.
3) Differentiate between analog and digital communication.
Answer:
For IBDP Physics, you should know:
1) The answer is "adjustable." Because a practical basic microscope lacks an adjustable magnification, compound microscopes are used. In a compound microscope, the focus can be changed based on the situation.
2) The lowest frequency of light that, when it strikes a metal surface, triggers the emission of electrons is known as the threshold frequency.
3) In analog transmission, data is conveyed using a modulated signal. TV and radio transmissions are common examples of analog communication.
Digital communication is a sort of communication where information is encoded as a collection of discrete numbers. Optical fibers and computer buses both use digital communication.
Work hard for your IBDP Physics examination!
