RADIO WAVES Use the chart on the lab station to answer the following questions 1. Do radio waves have a longer or a shorter wavelength than visible light? 2. Why do AM radio stations and FM radio stations stay separate and not mix together? 3. When traveling, why do you get to a point where your favorite radio station no longer comes in? MICROWAVES 1. Do microwaves have a longer or a shorter wavelength than visible light? 2. Why are hotspots in a microwave created? 3. Explain why the turntable in microwaves help heat your food evenly. INFRARED RADIATION 1. Which materials block the infrared light? 2. Which materials let the infrared light through? 3. Why can you not see the infrared light with the naked eye? 4. Does infrared light have a longer or shorter wavelength than visible light? VISIBLE LIGHT Place the CD (label up) on an angle on top of the projector. This should create a rainbow on the wall. Use what you see to answer the following questions 1. What colors are visible? 2. What happens to make these colors visible? 3 Name: ______________________________________________________________ Period: ____________ ULTRAVIOLET RADIATION 1. What happened to the white paper after it was left by the window? 2. Why didn’t a change occur on the whole sheet of paper? 3. What is contained in the sunlight that causes the observed results? 4. Does ultraviolet radiation have a longer or shorter wavelength than visible light? X­RAYS 1. How do you think the image of the bones show up on the film? 2. Why do you think that organs are not as clear in an x­ray? 3. To see organs, doctors can make patients drink a liquid containing the element barium. Why do you think can help? 4. Do X­Rays have longer or shorter wavelengths than visible light? X­RAYS STATION 2 1. In an x­ray, what do each of the pieces represent? ○ Pan­ ○ Sand­ ○ Foam Cutout­ 2. Why did you see what you did at the bottom of the pan? 3. What does this tell you about the strength of an x­ray compared to a bone? 4 Name: ______________________________________________________________ Period: ____________ GAMMA RAYS Read the article­ “Gamma­ray burst brightest ever seen” 1. Do gamma rays have longer or shorter wavelengths than visible light? 2. Do gamma rays have a lot of energy or a small amount of energy? 3. Why do most gamma rays from space not reach the Earth? 4. Gamma rays are used on Earth too. They are used in medicine to kill cancer cells. They are also used in the food industry to kill bacteria, like E.coli, that may be present in fruits and vegetables. Do you think this is a good idea? Why or why not? EMS REVIEW VIDEOS Click on the two links on the science website and answer the following The Electromagnetic Spectrum: FRONTLINE 1. What makes up electromagnetic waves? 2. What role does the vibration of the particles play in the EMS waves? 3. Which types of rays have you been exposed to today? The Electromagnetic Spectrum: NASA 1. How many categories is the EMS divided into? 2. What type of wave cannot be seen but can be felt? 3. What type of wave is emitted by some radioactive material? 5 Name: ______________________________________________________________ Period: ____________ WAVES CONCLUSION 1.
