- Two waves, one traveling in water and another traveling in air, have the same frequency and the same wavelength. The speeds of the two waves are different because they are in different mediums the are the same because they have the same wavelegth and frequency are same in magnitude but opposite in direction because sound has a harder time going through water are impossible to determine without knowing the densities and temperatures of the two mediums.Organ pipe Y with an open end in both ends is twice as long as organ pipe X with an open end in one side.What is the ratio of the frequencies between that of organ pipe X and organ pipe Y: A)1:1 B)1:2 C)2:1 D)1:4 E)4:1A wave has a period of 0.45 s. What is the frequency? INCLUDE UNIT.

If 1 bug makes a sound of 8 dB then what will 25 bugs sound like? 12. If 4 bugs make a sound of 14 dB then what will 25 bugs sound like?As a sound wave propagates further over time, which of the following would be true? * O The ampltidue of the wave will slowly increase over time O The frequency of the wave will increase as it travels further O The intensity of the sound wave will decrease O The pitch of the sound wave will decrease None of the above will occur
- If the sound waves produced by a speaker change to a much higher frequency, what would it sound like? O quieter O louder O lower in pitch O higher in pitch(Figure 1) shows the displacement of a standing sound wave in a 32-cm-long horizontal tube of air open at both ends.
