Answer 1

(b) That converts radio frequency signal into electromagnetic energy.

Answer 2

Answer:

According to the question the answer is option "b) That converts radio frequency signals into electromagnetic energy". The reason for the answer is because there are signals are broadcast ed in the atmosphere, in the electromagnetic waves, by the senders of the signal.

Explanation:

When there are waves received by antenna, it instantly converts it into electromagnetic signals, so that they could be decoded by the receiving devices, and display the appropriate message. The way of transferring data, through air, has many noise in the channel, and even gets corrupted, even due to bad weather conditions.
