10.2 video lecture

What are the measurable characteristics of waves discussed in this section?

• Wavelength, frequency, amplitude, and wave speed

• Color, temperature, density, and mass

• Shape, size, texture, and weight

• Volume, pressure, duration, and intensity

In a transverse wave, what is the term for the highest point of the wave?

• Trough

• Amplitude

• Crest

• Wavelength

How is the wavelength of a compressional wave measured?

• From a rarefaction to a compression

• From the midpoint to the highest point

• Between two consecutive compressions or two consecutive rarefactions

• From the start of the wave to its end

What is the SI unit for frequency?

• Meter

• Second

• Hertz

• Joule

What is the relationship between frequency and wavelength?

• They are directly proportional

• They are inversely proportional

• They are unrelated

• They are always equal

A wave has a wavelength of 2.5 meters and a frequency of 170.5 Hz. What is its speed?

• 68.2 m/s

• 426.25 m/s

• 173 m/s

• 0.014 m/s

For a compressional wave, what does the amplitude measure?

• The height of the wave

• The distance between compressions

• The closeness of the coils or particles

• The speed of the wave
