Assignment on experiment reports....need help (1 Viewer)

[kazza9]

Hey guys,
I'm currently doing an assignment where I have to write up 3 reports on different experiments. I've managed to get one done but i'm stuck on the other two because I don't know what I should be measuring for my results table....Any help would be greatly appreciated...here's the two experiments.
1.perform an investigation to model the generation of an electric current by moving a magnet in a coil or a coil near a magnet.
2. Perform an investigation to demonstrate the production and reception of radio waves.

By reports, I'm assuming a practical write up ??


1. You insert a magnet in and out of a solenoid, there's an induction of current due to relative motion and lenz's law

2. Production of radio waves the same way Hertz did.

Thanks ...I've finished one of them but now I have to do the generation of radio waves.....The experiment says I have to demonstrate it....that part is easy I just need to think of something I have to Measure for the results and calculations......Any help on a formula and something i should measure?

Ummm... when we demonstrated it, the teacher brought out this device where you tap it and it generates EM waves and that wave would be transmitted by a nearby radio player.


We didn't 'calculate' or 'measure' anything. But if you want, you can have a look at Physics 2 Jacaranda where the aerial affects the frequency of the waves.

Mabs, c= λf... E=hf. Idk
