Question
Choose ALL correct answers. The advantages to making the spectroscope slit wider are thatSelect one or more:a.faint emission lines become more visible.b.emission spectra turn into continuous spectra.c.it is easier to determine a more precise value of the wavelength.d.closely spaced spectral lines are better resolved.
Solution
The correct answer is:
a. faint emission lines become more visible.
Making the spectroscope slit wider allows more light to enter, which can make faint emission lines more visible. However, it does not turn emission spectra into continuous spectra (b), nor does it make it easier to determine a more precise value of the wavelength (c). In fact, a wider slit can actually decrease the resolution of the spectroscope, making closely spaced spectral lines less well resolved (d).
