JEE Main & Advanced Physics Communication System / संचार तंत्र Question Bank Assertion and Reason

  • question_answer
    Assertion             :       Microwave propagation is better than the sky wave propagation. Reason                 :       Microwaves have frequencies 100 to 300 GHz, which have very good directional properties.

    A)             If both assertion and reason are true and the reason is the correct explanation of the assertion.

    B)             If both assertion and reason are true but reason is not the correct explanation of the assertion.

    C)             If assertion is true but reason is false.

    D)             If the assertion and reason both are false.

    E)             If assertion is false but reason is true.

    Correct Answer: A

    Solution :

                Microwaves have got good directional properties. Due to it, the microwaves can be directed as beam signals in a particular direction, much better than radio waves, because microwaves do not bend around the corners of any obstacle coming in their way.
