Bell Work Monday 921 Get out a sheet

Bell Work Monday (9/21) �Get out a sheet of paper. �At the top, write “Bell Work. ” �Write “Monday” and answer the following questions. 1. Draw a transverse wave. 2. Label the crest and trough on your wave. 3. Draw a longitudinal wave. 4. Label the compression and rarefaction on your wave.

(9/22) �Get out a Bell Work paper. �Write “Tuesday” and answer the following questions. 1. Draw a transverse wave. 2. Label the rest position, crest, and trough on your wave. 3. Label amplitude and wavelength.

Bell Work Wednesday (9/22) �Get out a Bell Work paper. �Write “Wednesday” and answer the following questions. Determine the following: 1. Amplitude 2. Wavelength 3. Frequency 4. Wave Speed

Properties of Waves Foldable �Directions: Cut on the dashed lines. Fold on the solid line. Describe each property. Explain the relationship between each.

Amplitude

Amplitude �How far in a medium the wave travels �Maximum distance the wave moves from the rest position � Energy, Amplitude (directly proportional �For longitudinal wave, how compressed or rarefied the medium becomes

Wavelength

Wavelength �Distance between 2 identical spots on a wave �To measure: �Transverse waves – distance from crest to crest or trough to trough �Longitudinal waves – distance from compression to compression or rarefaction to rarefaction

Frequency

Frequency �Number of waves in an amount of time �Measured in Hertz (Hz) �Number of waves per second

Speed

Speed �How far the wave travels in a given time �To calculate: �Distance divided by time �Speed = wavelength x frequency �Speed remains constant if medium, temperature, and pressure do not change

�Wavelength = speed/frequency

�Frequency = speed/wavelength
