Physics Practice Sheet 2: Wavelength & Frequency of Visible Light Name _______________________ Date ________________________ 1. For electromagnetic radiation, the speed is constant (3.0 x 108 m/s). When looking at the equation v = f, what is the relationship between wavelength and frequency? 2. Which type of electromagnetic radiation has the higher frequency, x-rays or microwaves? How do the wavelengths of the two types compare? 3. Of the colors red and blue, which has the longest wavelength? 4. Of the colors orange and violet, which has the shortest wavelength? 5. Suppose you add green and blue light together. What color will result? 6. If you wanted to make the color green, what paints (pigments) should you mix together? 7. During a theatrical production, a magenta light is desired. What colors of light should the lighting crew add together to achieve the magenta color? 8. A chair is blue when white light is directed towards it because the chair absorbs all of the other colors of the spectrum of light and reflects only blue. What color would this blue chair be if instead of white light, green light were shone on it?
