4 MEMBERS TO A TABLE TAKE YOUR IPAD

AT THE TABLE 7 MINUTES READ THE DIRECTIONS AND MAKE A WORD CHART USING THE WORDS IN THE ENVELOPE, TAKE A PICTURE OF YOUR CHART

-Wave length -Frequency Word Bank -Waves -Amplitude -Wave length -Frequency -Electromagnetic wave -Electromagnetic spectrum -Mechanical wave

The Nature of Waves Write down as much as you can think of when you hear the word waves….

What exactly is a wave? Wave: Any disturbance that can distribute and can transmit energy through matter or space. Matter meaning liquids, gases, or solids Other examples…. Radio waves Analog or HD digital TV signals Cellular reception Microwave ovens SONAR Light waves from the sun Crossfit ropes

Waves Carry Energy Medium: solid, liquid, or gas through which waves can travel Waves carry energy through the medium….not the medium carries the wave energy Waves do work on everything in its path…. Ex. Waves at the beach List 3 other examples

Energy Transfer without a Medium We are talking space We cannot hear sound in space, because it needs a medium Some waves travel MUCH faster in space Examples Light waves from the sun List 2 more

Amplitude Amplitude: maximum distance a wave vibrates from its rest position Rest position means neutral Larger the amplitude, the taller the wave is Larger Amplitude means more energy placed in to the wave.

Wavelength Wavelength: distance between 2 adjacent crests or compressions in a series of waves. Can also be measured on the trough of a wave

Frequency Frequency: Number of waves produced over a given time period Waves can be counted by the number of crests or troughs that pass a point over a certain amount of time. Directly related to a wave’s wavelength Expressed in hertz (Hz). 1 Hz = 1/s Higher frequency = more energy Longer wavelength = less energy

Types of Waves Transverse Wave Particles in the medium wave vibrate up and down Transverse means moving across Ex…crossfit ropes Longitudinal Waves Particles in the medium vibrate back and forth Push on a spring Compression: portions are tighter than normal Rarefaction: particles are less crowded together

www.phet.colorado.edu → Wave On A String Just Google It Take 5 minutes to mess around with the simulation First 2 minutes on Manual Second 2 minutes on Oscillate Last minute → “you do you” When you are done, you owe me an entry in your Science Thinking Log Tell me about the simulation. What things did you decide to manipulate? What did you notice as you messed around with the simulation?
