Physics P3 and P4

Today we're starting the first assignment for physics.  You will need to work in a powerpoint, which we will print off later. Questions 1, 2, and 3 are for P3, 4 and 5 are for P4.

1. Find a good image for the electromagnetic spectrum, and copy it into the middle of your slide. Find something like the ones below with different waves labelled would be good:                                                                                        
2. Use this link to briefly explain what 5 of the waves are used for, eg. 'microwaves are used for cooking.' Write these in text boxes with lines to where the waves are in the spectrum.
3. Copy and complete this sentence - Radio waves have a high wavelength and a low frequency, while gamma rays have a high                and a             wavelength. Use this page to help if you aren't sure.
4. Use this page to explain what types of ionizing radiation there are, and what it can do to cells in our bodies.
5. Explain what makes up the three types of ionizing radiation, using a table like this one:

   Radiation:	Made of:
   Alpha
   Beta
   Gamma
