You will be going to 12 stations, at each station there will be a mini-lab. Follow the instructions at the lab and in your notebook record the following. You do not have to do the labs in order: 1.The number of the lab 2.Describe what you observe 3.Answer any questions from the labs’ sheet 4.Describe the concept learned from what you observed—especially describe what characteristic of light you are seeing. 5.Apply the concept to what this means to everyday use or how this characteristic of light is useful.

Quiz 1.Which has greater wavelength red or blue? 2.Which has greater frequency, red or yellow 3. Which has greater energy, yellow or violet 4.What waves have the greatest frequency? 5.velocity=frequency x _____________ Answers: red yellow violet gamma wavelength
