    CBSE Guess Paper for Class 12 Physics Board Exam 2019: Some sample questions

    Question: Name the essential components of a communication system.


    Essential components of a communication system are:

    Information source, transmitter, communication channel, receiver,

    Question: The electric field at the outer surface of a hollow charged conductor is normal to the surface, explain.


    The outer surface of a charged conductor act as an equipotential surface, so, the electric field due to the conductor is normal to its surface.

    Question: Which of the following has the shortest wavelengths?

    Ultraviolet Rays, Microwaves, Infrared Rays, X-Rays



    Question: Which part of electromagnetic spectrum has the largest penetrating power?


    Gamma rays.

    Question: A converging lens is kept co-axially in contact with a diverging lens – both the lenses being of equal focal lengths. What is the focal length of the combination?


    Suppose focal length of converging and diverging lenses be + f and ‒ f respectively.

    Power of converging lens P1 = 1/f, power of diverging lens P2 = ‒ 1/f

    Power of combination = P1 + P2 = 0.

    Question: Define cut-off potential?


    It is the negative potential applied to the node which completely stops the photoelectric current.

    Question: What is the relation between energy (E) and momentum (p) of a photon?


    E = p c


    c → velocity of light.
