Many musical instruments use “boxes” as part of the instrument. some examples are acoustic guitars and pianos. from your experience in this lab on building your own musical instrument, write a brief essay on the purpose of these “boxes”. include a brief description of a xylophone and what it uses for the purpose of the box.

Explanation:

A box resonate the sound hence is used in musical instruments.

While vibrations are produced by musical instruments, frequencies are created which are more enhanced in a wooden box.

For example :  Xylophone is a musical instrument that consist of wooden bars struck by mallet.

Under each bar of the xylophone there is a there is a resonator tube which amplifies the sound.

So when the wooden bars are struck, xylophones produces sound and the pitch of the sound depends on the size of the bars. Longer the bar, the more longer sound will be resonating in it hence lower will be the pitch.

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.
