Which hears the sound of shorter wavelengths

Here, the lower-frequency sounds are emitted by the large speaker, called a woofer, while the higher-frequency sounds are emitted by the small speaker, called a tweeter. Calculate the wavelengths of sounds at the extremes of the audible range, 20 and 20, Hz, in Assume that the frequency values are accurate to two significant figures. The speed of sound can change when sound travels from one medium to another. However, the frequency usually remains the same because it is like a driven oscillation and has the frequency of the original source.

Suspend a sheet of paper so that the top edge of the paper is fixed and the bottom edge is free to move. You could tape the top edge of the paper to the edge of a table. Gently blow near the edge of the bottom of the sheet and note how the sheet moves. Speak softly and then louder such that the sounds hit the edge of the bottom of the paper, and note how the sheet moves. Explain the effects. Imagine you observe two fireworks explode. You hear the explosion of one as soon as you see it.

However, you see the other firework for several milliseconds before you hear the explosion. Explain why this is so. Sound and light both travel at definite speeds. The speed of sound is slower than the speed of light. The first firework is probably very close by, so the speed difference is not noticeable.

The second firework is farther away, so the light arrives at your eyes noticeably sooner than the sound wave arrives at your ears. You observe two musical instruments that you cannot identify. One plays high-pitch sounds and the other plays low-pitch sounds. How could you determine which is which without hearing either of them play? Compare their sizes. High-pitch instruments are generally smaller than low-pitch instruments because they generate a smaller wavelength.

Objects like ships or large pieces of airplanes can be found by sonar, while smaller pieces must be found by other means. Skip to main content.
