5. Different types of EM radiation26 Mar Class listSeating Plan Task: make light waves

6. Different types of EM radiation26 Mar Class listSeating Plan Task: make light waves The waves should all have the same amplitude( height). Instead of μm we will use mm. So 400 μm will be 400 mm. Make the total length of all your waves together the same. About 3 or 4 metres.

9. Different types of EM radiation26 Mar Class listSeating Plan Cats vs humans (extension task) Cats have much better night vision than humans They can’t see colour though. This has to do with the amount of rods and cones in their retina. Q) What difference do you imagine there is between the amount of rods and Cones in a cat’s eye versus a human’s eye and why does this affect their night and colour vision?
