Question

_ are the most senstive detectors for the visible and near UV regions in the spectrophotometer​

Answer 1

Explanation:

The most common type of light detector in UV/Vis spectrophotometers is the photomultiplier tube (PMT). The wavelength range for PMT's is from 150 nm to 900 nm, although the region between 850 nm to 900 nm is marginal. PMT's are one of the most sensitive light detectors made

Answer 2

Answer:

The human eye is sensitive to light in the visible region, and is most sensitive to green light with a wavelength of around 550 nm.

photomultiplier tube

The photomultiplier tube is a commonly used detector in UV-Vis spectroscopy. It consists of a photoemissive cathode (a cathode which emits electrons when struck by photons of radiation), several dynodes (which emit several electrons for each electron striking them) and an anode.

Glad help you!!
