Wave Properties and Calculations

The video tutorial guides students through a waves lab activity using a gizmo simulation. It covers setting up the simulation, observing wave motions, measuring wavelengths and amplitudes for both transverse and longitudinal waves, and calculating frequency and period. The tutorial emphasizes the importance of correct initial settings and provides step-by-step instructions for each task.

What is the initial amplitude set for the transverse wave in the Waves Lab Gizmo?

• 30

• 20

• 40

• 10

In a transverse wave, how does the crest move?

• Back and forth

• In a circular motion

• Left to right

• Up and down

What is the distance between two successive crests in a transverse wave called?

• Amplitude

• Period

• Wavelength

After changing the density from two to one, what is the new wavelength measured?

• 100 cm

• 160 cm

• 120 cm

• 140 cm

How is the amplitude of a transverse wave defined?

• The distance from crest to trough

• The total height of the wave

• The maximum displacement from the resting position

• The distance between two crests

In a longitudinal wave, what is the motion of the hand?

• Left to right

• Diagonal

• Up and down

• Circular

What is the wavelength of a longitudinal wave measured between?

• Two troughs

• Two crests

• Two amplitudes

• Two compressions

What is the amplitude of the longitudinal wave if the total width is 20 cm?

• 5 cm

• 20 cm

• 10 cm

How is the frequency of a wave calculated from its period?

• Multiply the period by 2

• Divide 1 by the period

• Add the period to itself
