We know that 'migrate' means to move. So since that, we need to add the -ing, and we know that we end up with the meaning "moving".
So migrating means moving from one place to another.
Incomplete question. However, I assumed you are referring to the article <em>"An Inspector Calls and J B Priestley’s political journey" </em>by Alison Cullingford.
<u>Explanation:</u>
In that article the five words that Cullingford uses to describe the ‘golden age' were:
- freedom,
- plenty,
- hospitality,
- conviviality,
- generosity.
He uses such words in other to highlight the contrasts between past experiences and the present one in which Bradford found himself.
The play would be helpful here.
The electromagnetic wave is self propagating, what I mean by that is, an electric field generates a magnetic field at 90 degree phase angle, and the magnetic wave you get as a result generates the electric wave at the same phase angle. The interchange of electric to magnetic and vice versa continues and lets the electromagnetic waves to travel without any medium. Quite interesting, really!
