1 Washtenaw County Elementary Science Olympiad Photon Phun Workshop 2 Wave and Light Properties Prof. Katsuyo Thornton Prof. Max Shtein Dept. of Materials Science and Engineering Univ. of Michigan Presented at Scarlett Middle School Financial support by National Science Foundation
2 What will we learn today? What is wave? Electromagnetic wave Electromagnetic spectrum & colors of light Prisms Grating and spectroscope See materials section at the end for the supplies for activities
3 Examples of waves?
4 Examples of waves? Ocean waves Sound waves Waves on rope Light! (Of course!)
5 What is wave?
6 What is wave? Oscillation Something goes up and down Vibration
7 Activity 1: How do we create Take a rope waves? Have one person hold one side and make it pretty taut Another person wiggle one side Wiggle fast and slow; do you see a change?
8 What makes waves?
9 What makes waves? Vibration Oscillation
10 Sound is a pressure wave Sound is a wave due to variation of density/pressure of air or other media
11 Light is electromagnetic wave Electromagnetic wave has oscillating electric field and magnetic field These fields are coupled
12 Characteristic of waves: Wavelength & frequency Wavelength = length of the repeating unit (example: the maximum to next maximum point) Image by Bryan Derksen (on English Wikipedia)
13 Characteristic of waves: Wavelength & frequency Wavelength = length of the repeating unit (example: the maximum to next maximum point) Image by Bryan Derksen (on English Wikipedia) Image:
14 Characteristic of waves: Wavelength & frequency Wavelength = length of the repeating unit (example: the maximum to next maximum point) Frequency = how frequently it goes from one shape to the same shape again Image by Bryan Derksen (on English Wikipedia) Image:
15 Activity 2: Wave Characteristic Exercise (see the handout) Count how many times this wave goes up and down in one minute (use the cell phone timer) Frequency = (the count)/min = (the count/60sec) 1 Hz (1 Hertz) = 1/sec Image:
16 Frequency & wavelength Faster you wiggled the rope (higher frequency), the wavelength became. When you wiggled slower, the wave length became. The wavelength and frequency are inversely related.
17 Wavelength, frequency, and energy Do you put more energy to make a wave with longer wavelength? Do you put more energy to make a wave with shorter wavelength? Try out the rope again!
18 Electromagnetic (EM) wave Electromagnetic wave has oscillating electric field and magnetic field These fields are coupled We will focus on EM wave from here on
19 Visualizing EM wave EM waves travels Image:
20 Wavelength/frequency determine the color (many of them we can t see!) Image: media/file:em_spectrum_properties_edit.svg
21 Visible light Image:
22 Different light source gives out different wavelengths White light is composed of at least three color of light Different source of light gives out different set of wavelengths/ frequencies of light
23 Prisms can spread light according to the wavelength! Light that pass through when they encounter a new medium (material) refracts (bends) Light with different colors interact differently with materials and bend differently Image:
24 Grating can also spread light Diffraction happens because a wave adds constructively or distractively Destructive Constructive These two waves adds to this Image:
25 Depending on the wavelengths, it adds up constructively at certain angles This is why you see colors on bubbles! We use a CD, which acts as a diffraction grating because of the grooves on the surface
26 Activity 3: Handmade Spectroscope Make a small scratch on a CD-R Put a tape on the scratch and over the CD; pull off to remove the reflective material; repeat until all removed Cover half of the CD with a foil with straight edge Cover the other side with another piece, leaving 1mm gap
27 What did you see? Continuous spectrum? Discrete (disconnected) spectrum? What was your favorite?
28 Take-away Light is EM wave A wave is characterized by their wavelength/frequency; you learned how to measure them Wavelength/frequency determine the color; visible range is ~400nm to ~700 nm You can use prisms or grating to separate the color
29 Thanks! Questions?
