Answer:
Beats are the difference in frequency.
(a) is correct option.
Explanation:
Beat :
Beat is the difference of the frequency of two waves.
The difference in frequency is equal to the number of beat per second.
Amplitude :
Amplitude of the wave is the maximum displacement.
Frequency :
Frequency is the number oscillations of wave in per second.
Intensity :
Intensity is the power per unit area.
Hence, Beats are the difference in frequency.

Explanation:
Sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. ... Radio is a form of electromagnetic radiation just like light and can therefore travel through the vacuum of space just fine
<h3><u>Answer;</u></h3>
Isomers
<h3><u>Explanation</u>;</h3>
- <em><u>Isomers are compounds with the same molecular formula but different structural formula. They have the same molecular formula, but have a different arrangement of the atoms in space.</u></em>
- isomerism excludes any different arrangements which areas a result of the molecule rotating as a whole, or rotating about particular bonds.
- Isomerism may be structural isomerism where atoms are arranged in different order, or may be chain isomerism which occur as a result of branching in carbon chains.
