Science Projects MONTUESWEDSTHURSFRISATSUN Science Projects Due School Science Fair Today Break Due Test Review for test

Review EM 1. What type of wave? 2. What does it look like? 3. What mediums can it travel through? 4. How can we see the colors from white light? 5. Which type of wave has the longest wavelength? 6. Which type of wave has the highest frequency? Transverse ALL – S, L, G, OSpace Prism Radio Gamma Ray

Colors we see?

Light Activity In your notebook, title this “LIGHT ACTIVITY” Use the different instruments to answer these questions in your notebook: 1. What do you see/observe when you use the spectroscope 2. How does the light compare when you see white light vs. colored light 3. How did you use the prism?
