Slide1123.2 Waves
A
wave
is an oscillation that travels from one place to another.If you poke a floating ball, it oscillates up and down.The oscillation spreads outward from where it started.
Slide1223.2 Waves
Waves are a traveling form of energy because they can change motion.
Waves also carry information, such as sound, pictures, or even numbers.
Slide1323.2 Frequency, amplitude, and wavelength
You can think of a wave as a moving series of high points and low points.
A
crest is the high point of the wave. A trough is the low point.
Slide1423.2 Frequency
The
frequency
of a wave is “how often” the wave moves up and down. Measured in Hertz (Hz)
Slide1523.2 Amplitude
The
amplitude of a water wave is the maximum height the wave rises above the level surface.
Slide1623.2 Wavelength
Wavelength
is the distance from any point on a wave to the same point on the next cycle of the wave
.
Slide17Label the wave
Crest, trough, equilibrium, wavelength, amplitude
Slide18Slide19Animation
How could we increase the frequency? Decrease?
How could we increase the amplitude? Decrease?How could we increase wavelength? Decrease?
Slide2023.2 The speed of waves
The speed of a water wave is how fast the wave spreads, NOT how fast the water surface moves up and down or how fast the dropped ball moves in the water.
How do we measure the wave speed?
Slide21IMPORTANT! COPY THIS!
Slide22CFU!!
The wavelength of a wave on a string is 1 meter and its speed is 5 m/s.
Calculate the
frequency and the period of the wave.

Solution:
Slide23CFU!!
The wavelength of a wave is 0.5 meter and its period is 2 seconds. What
is the
speed of this wave?The wavelength of a wave is 100 meters and its frequency is 25 hertz. What is the speed of this wave? What is its period?
Slide24Activity
In groups, you will try to solve a mystery word for a prize.
Here’s how you will do it!
Each question on the skill sheet is worth a specific letter or two.Once you solve a question, raise your hand and once your cleared (if correct) you will receive a letter.YOU CANNOT GUESS THE WORD, YOU CAN ONLY SOLVE FOR IT!There can only be ONE GROUP WINNER!
