  1. Question 1

    Q1. TV transmission cannot cover a very large area because:

    • A) The strength of TV waves is very limited
    • B) A picture cannot be transmitted clearly after a specific distance
    • C) The shape of the Earth is spherical
    • D) The air is not a good conductor of light and sound/waves

    Answer: The shape of the Earth is spherical

    Explanation: Television signals travel in straight lines and cannot follow the curvature of the Earth, so the spherical shape of the Earth limits the coverage area of TV transmission.
