Waves+and+the+Electromagnetic+spectrum

= Waves and the electromagnetic spectrum = =Part I: **What is the physics of waves (notes)?**= Go to the following website and read about general wave motion.**General motion waves** Take notes Cornell style on the following:
 * What is the difference between transverse and compressional waves?
 * What kind of waves is light or electromagnetic waves?
 * What are the components of transverse waves?
 * frequency with units
 * amplitude with units
 * wavelength with units
 * velocity with units
 * Draw a transverse wave and label the wavelength and amplitude.

=Part II: Waves-on-a-string Applet=
 * **Play around with waves on a string then answer question number 1 below: []**

=**Part III: What is the electromagnetic spectrum (notes)?**=

Take notes, Cornell style on the electromagnetic spectrum Go to Electromagnetic spectrum and answer the questions below.
 * What is the electromagnetic spectrum?
 * What are the names of the different wavelengths?
 * What is the speed of light?
 * How are these waves created and detected?
 * What is the relationship between energy and the frequency of waves (as frequency goes up, what happens to energy[|the relationship between wavelength and energy]
 * **Learn** the names of the wavelengths and **draw** wavelengths of radio and gamma rays in the ER spectrum by going to ER
 * watch the video on brainpop on Electromagnetic Spectrum [|Username and password is cougarsrule]

Spectrum above was taken from []


 * Look at the spectrum above. What are the four types of UV light and what is the difference in them?
 * Take notes on the information below:

--breaks O2 into to radicals --O radical combines with O2 to form ozone Check out the relationship between wavelength and frequency on http://hyperphysics.phy-astr.gsu.edu/hbase/ems1.html
 * UV light =** wavelengths from 0.1 and 0.4 mm
 * Three types:**
 * 1) **UVA==**longest can cause some damage to living cells---goes through ozone layer
 * 2) **UVB=**most attn is paid to this. fairly energetic, strongly absorbed by ozone layer—ozone gas is the only thing that can stop UVb
 * 3) **UVC=** most energetic and shortest---absorbed by ozone layer
