You will find most of your answers on the 6th Science Web page - or at the Web links provided there.
1. Mechanical Waves need matter to travel through.
2. Visible Light is a series of electromagnetic waves that our eyes can detect.
3. The amplitude of a wave is measured from crest to trough.
4. Microwaves are longer than visible light waves.
5. X-rays are about the size of atoms.
11. Points A, E and H are called .
12. Points C and J are called .
13. What is the distance from point B to point F called? .
14. Perpendicular from the blue line to points A, C, E, H or J is called the wave's .
15. From point C to point J is how many wavelengths?
16. Place your own point "K" on the diagram that is one wavelength away from point F. (Do this after you print out the completed assignment.)
17. The blue line in the diagram is referred to as the wave's .
(Please keep your answers within the text boxes.)
18. Using the "Wiggle Wrench" link set the animation to these settings:
Pulse selected with Amplitude = 50, Pulse Width = 50, Damping = 0, Rulers and Loose End both selected.
Pulse one wave. When the wave gets to the metal rod what does it do? When the wave gets back to the pulse generator what does the wave do? Describe the difference between the two. When a wave bounces off of something what is that called?
19. Using the same settings for the Wiggle Wrench pulse two waves. What happens when when the crest of one wave collides with the crest of the other wave? Describe using the term amplitude. You may have to use the Pause/Play and Step options to watch the waves.
20. Using the same settings for the Wiggle Wrench pulse another two waves. What happens when when the crest of one wave collides with the trough of the other wave? Describe using the term amplitude.
21. In 19 and 20, after the waves have collided have the waves changed their shape or size in any way? Use the word "energy" in your answer.
22. Keep all settings the same except change Amplitude to 100. Pulse one wave. Pause the wave. Using the horizontal ruler, what is the distance from the front to the back of the wave in centimeters (roughly)? How does this measurement relate to the Pulse Width setting of 50? Is the Pulse Width setting the wavelength of the wave? (Explain.)
