🌊 Day 5 of Waves

I Can Statements

I can use the Wavespeed Triangle.

I can calculate the speed of a wave.

I can calculate the wavelength of a wave.

I can calculate the frequency of a wave.

Wave Speed Equation

• wave speed = wavelength x frequency

• Use the triangle to rearrange the wave speed equation. Cover the unit you need to calculate.

• The horizontal line represents division.

• The vertical line represents multiplication

Multiple Choice

The vertical line means

• addition

• subtraction

• multiplication

• division

Multiple Choice

The horizontal line means

• addition

• subtraction

• multiplication

• division

Multiple Choice

Frequency =

• Wave speed * Wavelength

• Wave speed / Wavelength

• Wave speed + Wavelength

• Wave speed - Wavelength

Multiple Choice

Wavelength =

• Wavespeed * Frequency

• Wavespeed / Frequency

• Frequency * Wavespeed

• Frequency/wave speed

Multiple Choice

Wavespeed =

• Wavelength * Frequency

• Wavelength / Frequency

• Wavelength + Frequency

• Wavelength - Frequency

Calculating Velocity, Wavelength, and Frequency...

• Make sure that your units "cancel out"

• Your answer must include the correct units

• Refer back to the triangle!

• Ask for help :)

Multiple Choice

Multiple Choice

What is the frequency of a wave traveling at 300 m/s with a 4 m wavelength?

• 0.013 Hz

• 75 Hz

• 300 Hz

• 1200 Hz

Multiple Select

Check all that apply:

• I can use the Wave Speed Triangle.

• I can calculate the speed of a wave.

• I can calculate the wavelength of a wave.

• I can calculate the frequency of a wave.

• I understand that using the wrong unit or forgetting to put units in my final answer will cause Ms. Vandenberg to take off points from my work.
