A system consists of an oscillator and a speaker that emits a 1,000.-hertz sound wave. A microphone detects the sound wave 1.00 meter from the speaker.

1) Which type of wave is emitted by the speaker?

a. transverse

b. circular

c.longitudinal

d. electromagnetic

2)The microphone is moved to a new fixed location 0.50 meter in front of the speaker. Compared to the sound waves detected at the 1.00-meter position, the sound waves detected at the 0.50-meter position have a different

a. wave speed

b. frequency

c. wavelength

d. amplitude

3) The microphone is moved at constant speed from the 0.50-meter position back to its original position 1.00 meter from the speaker. Compared to the 1,000.-hertz frequency emitted by the speaker, the frequency detected by the moving microphone is

a. lower

b. higher

c. remains the same

4) A change in the speed of a wave as it enters a new medium produces a change in

a. frequency

b. period

c. phase

d. wavelength

5) A transverse wave with an amplitude of 1.15 meter and wavelength of 3.0 meters travels toward the right in a medium with a speed of 5.0 meters per second. Calculate the period of the wave.
