Waves

How can you measure the wavelength of a transverse wave?

• Measure from top of the wave to the rest position.

• Measure from the crest to the trough of the wave.

• Measure the distance between two corresponding parts of a wave.

• Measure from compression to compression in the wave.

Which wave has more energy? Why?

• Top wave because the amplitude is smaller

• Bottom wave because the amplitude is larger

• They are the same because the wavelengths are equal

• Top because the rarefactions are closer together

A ringing bell makes noise inside a glass jar. Then the air is removed from the glass jar using a vacuum pump. When all of the air leaves the jar, the sound of the ringing bell can no longer be heard. Which of the following best explains why the students can no longer hear the bell?

• Removing the air from the jar allows the bell to ring only very softly.

• The sound in the empty jar is reflected off the inside of the glass sides.

• The air in the jar provides a medium for the sound to travel through.

• The difference in pressure inside and outside the glass jar is too great.

Which of the following is TRUE?

• Wavelength is inversely related to frequency, so if wavelength increases, frequency decreases.

• Wavelength is directly related to frequency, so if wavelength increases, frequency increases.

• Wavelength does not affect frequency; they are independent of one another.

• Wavelength is inversely related to frequency, so if wavelength decreases, frequency decreases.
