Open Ended

How are waves and energy related? (Answer was in Bill Nye)

Multiple Select

What can we use to distinguish between two different waves? Select all that apply.

• Wavelength

• Frequency

• Amplitude

• We can't

• I'm not sure

Multiple Choice

If the particles of a medium are vibrating in the same direction of the travelling wave, then this is a ________ wave.

• Transverse

• Mechanical

• Longitudinal

• None of the above

• I'm not sure

Multiple Choice

If a transverse wave is travelling from East to West, then the particles of the medium would be vibrating in which direction?

• Both East and West

• Both North and South

• From East to West only

• From North to South only

• I'm not sure

Consider this image for the next question!

Poll

What do you believe is the relationship between Frequency and Wavelength? Think about all the activities and worksheets through this week.

• Inversely Related

  Higher Frequency = Lower Wavelength

  and

  Lower Frequency = Higher Wavelength

• Directly Related

  Higher Frequency = Higher Wavelength

  and

  Lower Frequency = Lower Wavlength

How are radio waves different from visible light rays and x-rays? (Answer was in Bill Nye)

Open Ended

Give two everyday examples of reflected waves. (Few examples were mentioned in Bill Nye)

Poll

How many complete waves are shown in this diagram?

• 1

• 2.5

• 3

• 1.5

• I'm not sure

Open Ended

What do you believe wave speed is? What wave properties that we have learned about, might affect wave speed?
