[求助] 【选择题】关于吸收光谱方面的两个知识点已有1人参与

1. What is the rule of thumb for setting the bandpass, so one obtains the most accurate spectrum (highest intensity and best peak shape)? <May have to look in the Cary Instrument Manual>
a. The bandpass is the same as the peakwidth.
b. The bandpass should be half of the peakwidth
c. The bandpass should be one-tenth of the peakwidth.
d. The bandpass should be one-hundredth of the peakwidth.
e. The bandpass should be twice as wide as the peakwidth.
2. What is meant by the term data interval?
a. The data interval is a synonym for bandpass or resolution.
b. The data interval is how closely spaced the digital points are taken in the attempt to make a representation of the analog signal.
c. The data interval is how closely spaced the analog points are taken in the attempt to make a representation of the digital signal.
d. The data interval is the total range of wavelengths that you scan during a spectroscopic analysis.

求大神解答这两道题,用简单的一两句话解释一下,多谢
