  1. (Mon) A sound wave has a velocity of 345 m/s in air. If the wavelength of the sound is 0.78 m, what is the frequency of the sound wave in air? (5 min / 6 pts)

  2. (Mon) A sound wave has a velocity of 345 m/s in air. If the wavelength of the sound is 0.78 m, what is the frequency of the sound wave in air? (5 min/6 pts) v = f x λ 345 m/s = (f)(0.78 m) V 345 m/s f = (345 m/s)/(0.78 m) ∕ f = 442.3 Hz f = λ 0.78 m f = 442.3 Hz

  3. (Tue) During the lab, you changed the pitch (frequency) of the sound several different ways. According to the formula v = f x λ, what are two ways to change the sound frequency and what did you do during the lab to make the change? (5 min / 8 pts)

  4. (Tue) During the lab, you changed the pitch (frequency) of the sound several different ways. According to the formula v = f x λ, what are two ways to change the sound frequency and what did you do during the lab to make the change? (5 min/8 pts) For a constant wave velocity: Change the wavelength Shorten the string (use finger or move stick) For a constant wavelength: Change the velocity Change string tension Change string mass

  5. (Wed) Yesterday we talked about 2 main types of waves and the different shapes these waves take. What is the type and shape of a light and sound wave? (5 min / 4 pts)

  6. (Wed) Yesterday we talked about 2 main types of waves and the different shapes these waves take. What is the type and shape of a light and sound wave? (5 min/4 pts) Sound Wave is a Mechanical Wave Longitudinal Wave Light Wave is a Electromagnetic Wave Transverse Wave

  7. End of Week Procedures • Add up all the points you got this week • Put the total number of points out of 18 points you earnedat the top of your page (no total, lose 5 points) • List any dates you were absent or tardy (and why) • Make sure your name and period # is on the top of the page (no name, no credit) • Turn in your papers
