Can anyone answer these:
1. Explain why the wave messages from television stations must occupy a broad bandwidth compared with
messages from radio stations.

2. Name 2 advantages of using AM radio waves in communication

2. Is cheaper then FM, can be transmitted over long distances and has lower bandwidth so it can have more stations available in any frequency range.

As for question one have you tried looking at the dotpoint books, CSU HSC online or sites like that to see what they mention?

What does "bandwidth" mean?
How do you know a waves bandwidth?

Yes they had nothing

That's not good as they had plenty of information back when I completed the course.

Bandwidth refers to the frequency range occupied by a modulated carrier wave. What I did find may be of use as to why its a broad range due to skipping certain ranges https://en.wikipedia.org/wiki/Television_channel
