Wave Properties and Calculations

The video tutorial explains how to interpret simple harmonic motion graphs. It covers the basic formula for periodic motion, V = wavelength x frequency, and demonstrates how to calculate wavelength, frequency, and period using graph data. The tutorial also highlights the difference between amplitude and wavelength and discusses the limitations of incomplete data in graph analysis.

What is the formula that describes all periodic motion?

• V = λ - f

• V = λ + f

• V = λ/f

• V = λf

In the first graph, what is the calculated wavelength?

• 10 meters

• 12 meters

• 15 meters

• 20 meters

How is frequency expressed in terms of period?

• f = 2T

• f = 1/T

• f = T/2

• f = T

What is the period of a wave with a frequency of 2 Hz?

• 0.5 seconds

• 0.25 seconds

• 1 second

• 2 seconds

What unit is commonly used to express frequency?

• Meters

• Seconds

• Hertz

• Cycles

In the second graph, what does 'a' represent?

• Wavelength

• Velocity

• Amplitude

• Frequency

What is the frequency of the wave in the second graph?

• 0.01 Hz

• 0.02 Hz

• 0.1 Hz

• 0.05 Hz

What is the period of the wave in the second graph?

• 75 seconds

• 100 seconds

• 50 seconds

• 25 seconds

Why can't the velocity be calculated from the second graph?

• The wavelength is unknown

• The frequency is unknown

• The time is unknown

What additional information is needed to calculate velocity in the second graph?

• Amplitude

• Wavelength or speed

• Frequency

• Time
