Model 1 – White Light - Livingston Public Schools



Name _________________________________________CP Chemistry 2015-16Kaspriskie Notes Chapter 5 Wave Properties ad RelationshipsWave Properties and RelationshipsFrom fireworks to stars, the color of light is useful in finding out what’s in matter. The emission of light by hydrogen and other atoms has played a key role in understanding the electronic structure of atoms. Trace materials, such as evidence from a crime scene, lead in paint or mercury in drinking water, can be identified by heating or burning the materials and examining the color(s) of light given off in the form of bright-line spectra.Model 1 – White LightTrace the arrows in Model 1 and shade in the table with colored pencils with the corresponding color.What happens to white light when it passes through a prism?Why are the color labels in the table in Model 1 plural (i.e., “Reds” rather than “Red”)?Do all colors of light travel at the same speed?Do all colors of light have the same energy? If no, which colors have the highest energy and the least energy, respectively? 6. Consider the light illustrated in Model 1.Which color corresponds to the longest wavelengths?Which color corresponds to the shortest wavelengths?601980031115000Write a sentence that describes the relationship between wavelength and energy of light.Model 2- Electromagnetic SpectrumRadiationEnergy (kJ)Wavelength (nm)Speed (m/s)Frequency (Hz)Radio0.0121 × 1063 × 1083 × 1010Microwave0.121 × 1053 × 1083 × 1011Infrared127503 × 1083 × 1013Visible2395503 × 1086 × 1014Ultraviolet4792803 × 1081.2 × 1015X-Ray1.2 × 10513 × 1083.0 × 1017Gamma Ray6 × 1060.023 × 1081.5 × 1019Do all types of radiation have the same speed?Do all types of radiation have the same energy?

If the frequency of a wave triples, what happens to the energy needed for the wave? (assume the speed and wavelength don’t change)A student modifies the wavelength of a wave by changing the energy. If the energy is cut in half, what must have happened to the wavelength?How can doubling the energy of a wave affect the frequency?
