Wave Period and Frequency

Mr. Anderson explains wave period and frequency, using flashing lights and wave diagrams to illustrate these concepts. He demonstrates how period and frequency are reciprocals and uses a PhET simulation to show practical applications. The video also covers problem-solving techniques for calculating period and frequency from wave diagrams.

What is the period of a light that flashes once every second?

• 1.5 seconds

• 0.5 seconds

• 1 second

• 2 seconds

If a light flashes every 2 seconds, what is its frequency?

• 0.5 hertz

• 1 hertz

• 2 hertz

• 0.25 hertz

How are period and frequency related?

• They are directly proportional

• They are inversely proportional

• They are unrelated

• They are equal

In a wave diagram with time on the x-axis, how do you find the period?

• Calculate the area under the wave

• Measure the distance between two peaks

• Count the number of waves

• Measure the height of the wave

In the simulation, if the period is 0.67 seconds, what is the frequency?

• 0.67 hertz

• 1 hertz

• 1.5 hertz

• 2 hertz
