Question
What should be the height of transmitting antenna if the TV telecast is to cover a radius of $128 \mathrm{~km} ?$(A) $1560 \mathrm{~m}$(B) $1280 \mathrm{~m}$(C) $1050 \mathrm{~m}$(D) $79 \mathrm{~m}$
Step 1
Step 1: The range of coverage of a TV telecast is given by the formula for the line of sight distance, which is $d = \sqrt{2hR}$, where $d$ is the distance, $h$ is the height of the antenna, and $R$ is the radius of the Earth. Show more…
