Chapter 7: Q 7.21 (page 194)

Distinguish among (a) a spectroscope, (b) a spectrograph, and (c) a spectrophotometer.

Short Answer

Expert verified

A spectroscope, spectrograph, and spectrophotometer all instruments are different from each other.

Step by step solution

01

Given Information.

We have to distinguish between a spectroscope, spectrograph, and spectrophotometer.

02

Step 2:

	Spectroscope	Spectrograph	Spectrophotometer
1)	It is an instrument used to measured the spectrum of light.	A spectrograph is the device that is used to separate the incoming light by its wavelength and frequency.	A spectrophotometer is the instrument in which disperse radiations are measured in specific sequence.
2)	The apparatus Isaac Newton used for spectroscope on the spectrum of light.	Telescope is the example of spectrograph.	A spectrophotometer are usually use in astronomy, chemical analysis etc.
