It depends on how fast you are going and in orincipal no
Line spectra are obtained when individual elements are heated using a high-voltage electrical discharge. This heating causes excitation of the element and a subsequent emission of distinct lines of colored light are obtained. Each element has its own unique emission line spectrum; therefore, if any of the tested substances were the same, their spectra would match. However, this is not the case so none of the substances are the same.
The amplitude of the sound waves coming out of the speaker
or headphones will increase, and your little brother will start
banging on the wall and telling you to turn it down.
From someone who has taken physics this is, True
