1 Diffraction A. Watch the following video entitled Apertures and Diffraction. Answer the comprehension questions provided in your Station packet. B. Draw and label the diffraction Diagram C. View and describe the example of diffraction. D. Copy the definition of diffraction listed on the slide

2 Diffraction A. Watch the following video entitled Apertures and Diffraction Answer the comprehension questions provided in your Station packet.

3 Diffraction Diagram B. Draw and Label the following picture in your Station Packet. *Note how the size of the aperture (opening) and length of wavelength affect the level of diffraction (spreading)

4 Diffraction C. View the following image. Discuss in your Station Packet how this image shows an example of diffraction in the real world.

5 Diffraction D. Copy the Definition of Diffraction into the space provided in your Station Packet: Diffraction: A wave interaction where waves bend when they pass around an edge or through a slit.

6 Interference Stations A. B. In your Station Packet, Define the terms constructive and destructive interference by copying the definitions. Describe how the following image is demonstrating Constructive Interference in your Station Packet. C. View the following video. IN the space provided in your Station Packet Discuss how the waves created by the water droplets are demonstrating Constructive interference. D. Draw and label the diagrams below that show Constructive and Destructive Interference.

7 Interference A. In your Station Packet, Define the terms constructive and destructive interference by copying the definitions below: Constructive interference occurs whenever two waves combine to make a wave with a larger amplitude. Destructive interference when the amplitudes of two waves combine producing a smaller amplitude.

8 Interference B. Describe how the following image is demonstrating Destructive Interference in your Station Packet.

9 Interference C. View the following video. In the space provided in your station packet discuss how the waves created by the water droplets are demonstrating destructive interference.

10 Interference D. Draw and label the diagrams below that show Constructive and Destructive Interference.

11 Wave Interactive Station 1: Reflection This station is made up of 4 parts (A-D) A. B. C. D. Draw and label the Law of Reflection diagram in the Space provided on your Pezzuto Brother s Introduction to Wave Interactions guided note sheet. View (Please do not touch) the demonstration setup on the lab station. Explain, in the box provided, how this demonstration uses the law of reflection to display a virtual image. Be sure to use the terms such as reflect, angle of incidence, angle of reflection, as well as waves of visible light to support your answer. Using the Google Chromebook provided at your station, watch the video on reflection provided on the screen. Answer the comprehension questions. Copy the Note slide on the table into the space provided on your guided note sheet.

16 D. Copy the Note Slide into Your Station Packet Reflection happens when an object or wave hits a surface through which it cannot pass, it bounces back. Law of Reflection Angle of Incidence = Angle of Reflection

17 Refraction A. B. C. D. Refraction Diagram- Copy the diagram into you Station Packet in the appropriate box. Disappearing Coin Demonstration and Video- Using the Google Chromebooks, view the Steve Spangler Video and observe the demonstration displayed on the station. Answer the Comprehension questions and note your observations in the space provided in your Station Packet. Observe the image. Explain the use of lenses in improving vision. Use terms such as refraction and focus. View the Indiana Jones Clip on the Google Chromebook as well as the straw in the glass provided at your table. Explain in the box provided how both examples utilize refraction. Use the terms medium and refraction in your answer.
