Vedclass · Answer

(A) Red glass acts as a color filter that allows only red light to pass through it while absorbing other wavelengths.Visible light wavelengths are approximately: Violet $(4000-4500 \ \mathring{A})$,Blue $(4500-5000 \ \mathring{A})$,Green $(5000-5700 \ \mathring{A})$,Yellow $(5700-5900 \ \mathring{A})$,Orange $(5900-6200 \ \mathring{A})$,and Red $(6200-7500 \ \mathring{A})$.Among the given wavelengths,$4700 \ \mathring{A}$ corresponds to blue light,$5400 \ \mathring{A}$ corresponds to green light,and $6500 \ \mathring{A}$ corresponds to red light.Since the light passes through red glass,only the red wavelength $(6500 \ \mathring{A})$ will be transmitted and seen in the spectrum.

$A$ source emits light of wavelengths $4700 \ \mathring{A}$,$5400 \ \mathring{A}$,and $6500 \ \mathring{A}$. The light passes through red glass before being tested by a spectrometer. Which wavelength is seen in the spectrum?
