s3w6 Mechanical waves

Reach chapter 18 on waves. Do you have any questions?

Measure and record the wavelength of the wave shown below. The rulers are already set up for you.

Measure and record the amplitude of the wave shown below. The rulers are already set up for you.

Flipping physics is back! do you have any questions?

The units for wavelength is typically considered a unit of length, but it may be easier to think of it as "the distance per cycle". The unit for frequency is frequently shown as 1/s, but it may be easier to think of it as the number of cycles per second. Period is frequently given a unit of time. Again, think of it more as seconds per cycle. What is the relationship between the period and the frequency

Oceans waves are best described as

Define the medium of a wave.

sound waves are best described as

the amplitude of a transverse wave like a ocean wave is the height above equilibrium. What does the amplitude look like in a longitudinal wave like sound?

if you double the frequency, what did you do to the period?

A girl is holding a slack string connected to a wall a few meters away. Moving her arm up and down the string starts to make waves. Explain how you know when the wave she creates becomes a standing wave.

(check all that apply) Does the doppler effect happen when the

How far, in terms of wavelength, does a wave travel in one period?

How fast does a bug need to be going to create a bow wave?

A jet is flying parallel to a busy street. Its velocity increases from just below the speed of sound to just above the speed of sound. Will everyone along the street hear the sonic boom at the same time? why or why not?

A skipper in a boat notices wave crests passing his anchor chain every 5 seconds. the distance between the wave crests is estimated to be 15 meters. be sure to add units. Find the wave speed. On level, there is a hint for you:

ocean waves would be described as

Find the wavelength of 600 hz sound if the speed of sound is 340 m/s

Middle C has a frequency of 256 hz. what is the period of one vibration?

Match the vocabulary term to its correct definition by dragging the definition next to the correct term.

As the frequency of a wave decreases, the energy of that wave:

If the amplitude of a wave increases, the energy of that wave:
