Wave Web Site Assignment

You are to create a website using www.weebly.com. This is a free web site design software on the internet.

Wave Introduction:

Imagine that your family has just returned home from a day at the beach. You had fun playing in the ocean under a hot sun. As you walk into the house, it's dark and you need to turn on the light in order to see where you are going. You put some cold pizza in the microwave for dinner, and you turn on the radio. Just then, the phone rings. Your friend is calling to ask about homework. In the scenario described above, how many types of waves can you identify? Can you name them? There were at least five of them. We come into contact with different waves every day of our lives and all day long. Rays from the sun are electromagnetic waves. So are the radio waves from your radio and T.V. Ocean waves carry ships and boats across long distances and allow us to have fun while swimming in them. The waves from the sun give us a cool tan. However, not all waves are harmless. Earthquakes cause seismic waves that travel through Earth's crust and cause million of dollars of destruction and many lives are lost. Let's take a closer look at these waves that affect every aspect of our lives on a daily basis.

You must define a wave and use the resources provided to answer the questions and create a web site. Be creative but your information must be accurate and specific. Create a scenario (a story), a cartoon character, a scene on the beach, whatever you want that will allow you to answer the questions provided below: TASK:

1) Develop a story board for your story. I will be grading the story board as part of your web site assignment. You may use the story board example provided or develop your own.

2) Each page of your website should address on of the standards (objectives) below.

Questions:

A. Use the following web site http://hyperphysics.phy- astr.gsu.edu/hbase/hframe.html (Description: "HyperPhysics is an exploration environment for concepts in physics which employs concept maps and other linking strategies to facilitate smooth navigation. For the most part, it is laid out in small segments or "cards", true to its original development in HyperCard. The entire environment is interconnected with thousands of links") to choose a specific wavelength of visible light, a radio wave, microwaves, and an x-ray to fill in the chart below. Remember your units! This must be part of your presentation.

Type of radiation Wavelength Frequency Wave Speed visible light ultraviolet radio waves microwaves (Note: this will be a chart on your page)

With wavelength?

7) What is the frequency range of UV light? Of Infrared light?

9) Rich says that light is the same thing as electromagnetic radiation. Do you agree or

disagree with Rich? Explain your response.

10) Do all animals see the same frequencies of “visible” light as humans do? Do all

animals hear the same frequencies of sound as humans do?

11) Why do astronomers use frequencies other than the visible ones when they are

investigating the universe?

D. http://www.ntia.doc.gov/osmhome/allochrt.pdf (questions 12-14)

12) What frequency range does the United States use for FM broadcasting? For AM

broadcasting?

13) What frequency does television channel 7 broadcast at?

14) How large a band of frequencies does each television broadcasting channel get? E. Use http://www.qrg.northwestern.edu/projects/vss/docs/thermal/3-what-makes-em-radiation.html (15-17) (Note:the general site http://www.qrg.northwestern.edu/projects/vss/docs/Communications/2-more-about-radio- waves.html (can also be used on other questions)

15) Why do materials absorb some frequencies of electromagnetic radiation and not

others?

16) Why do waves with frequencies higher than visible light hurt us while those with

lower frequencies do not affect us?

17) Light is sometimes described as a wave and sometimes as a particle. Give evidence

to support the wave nature of light.

#4 The user will be able to identify the difference between reflection, refraction, and absorption. http://www.youtube.com/watch?v=DThUKDM_Wtk http://www.youtube.com/watch?v=iletCKDCt_0&feature=related

(http://www.youtube.com/watch?v=M2wDLePcCQU&feature=related http://www.youtube.com/watch?v=7g0q1-Kkhvs&feature=related

Problem #1- How can you make a red dress look black by changing the lighting?

Problem #2- The scenes on the stage need white light only. There are no replacement lights for the blown lights.

The only replacement light bulbs are red, yellow, blue, purple, green, and orange. How can you make white light using these bulbs?

Problem #3 - What is the difference between light and sound. (The outline below was adpted from: The Physics Classroom: http://www.physicsclassroom.com/class/waves/u10l0a.cfm ; the majority of the pages below come from this site, which has been described above). Resources
