All must be able to state uses of radio waves (C Grade)
Most should be able to relate the properties of a radio wave to its uses (B Grade) Some could be able to explain refraction of radio waves (A/A* Grade) Today we looked at the use of EM waves in communications particularly radio waves and microwaves, comparing how the two are used. We modelled diffraction of radio and microwaves outside to investigate why Issy's radio worked in a valley by Jay's phone didn't and linked diffraction and refraction to the use of satellites. Prep: finish your poster on the EM spectrum and its uses. Due Tuesday Comments are closed.
