Question 1

• What is the time it takes to complete one cycle? (Time for one wavelength to pass a specific point) And what units are associated with this?

Answer

• The period of a wave…. • Corresponding units- Seconds(s)

Question 2

• If some wave has a velocity of 337.3 m/s… and a frequency of 192Hz, then what is the wavelength of this particular wave?

Answer

• Because wavelength= velocity over frequency, you take 337.3 and divide that by 192….. FINAL ANSWER= 1.757m

Question 3

• What is the number of oscillations or cycles a wave makes every second

• ( measured in Hz)

Answer

• This is known as the frequency of the wave…( waves over seconds)

Question 4

• Can you name two ways to solve for the velocity of any given wave?

Answer

• 1) Velocity= Distance/time• 2) Velocity= Wavelength*Frequency• 3) Velocity= Wavelength/Time

Question 5

• What exactly is a wavelength and how can it be measured?

Answer

• A wavelength is the distance from some exact point on a wave, to the same exact point on another wave….measured in meters…

Question 6

• How can you tell the difference between a transverse wave and a longitudinal wave?

Answer

• Visually, a longitudinal wave moves in the same direction that the wave is being produced….it also makes “compressions”.

• A transverse wave moves in the opposite direction that it being produced…looks much more traditional…
