Humans can hear frequencies between?

The audible range of frequencies for humans is, on average, between 20 Hz and 20kHz, although it varies between individuals. As humans age, however, this range normally decreases, especially on the higher end of the range.

What are the advantages of larger radio frequencies over smaller ones?

easier to transmit, higher frequencies radiate better. there is more bandwidth available at higher frequencies. higher frequencies travel in straighter lines so are more directional, this may or may not be an advantage depending on what is needed

Why do we use high frequency waves as carrier waves?

The use of high frequencies for carrier waves in communications permits a higher rate of information transfer than could be accomplished with lower frequencies. The higher frequencies have the potential for higher "data density" or "information density" than lower frequencies.

What is the relation between bandwith and gain?

The product of bandwidth and gain is constant. If bandwidth increases then gain decreases and vice versa.
