(a)
Interpretation:
The differences between the use of a hydrogen discharge lamp and deuterium discharge lamps as source for the ultraviolet radiations are to be explained.
Concept introduction:
The hydrogen discharge lamp as well as the deuterium discharge lamps are used to produce the radiations of ultraviolet radiations having the radiations of varied intensity depending on the usage of the discharge source in the lamp.
(b)
Interpretation:
The difference between the use of the filters and the monochromators as the wavelength selectors is to be explained.
Concept introduction:
The filters and the monochromators are specifically used for the selection of wavelength, but they are used differently based on their quantitative and qualitative applications. The filters as well as the monochromators are used as the wavelength selectors.But they both have their own fields of application.
(c)
Interpretation:
The difference between the use of photovoltaic cells and the phototubes as the
Concept introduction:
The photovoltaic cells as well as the phototubes work on the same principle. They both make use of the electromagnetic radiations incident on them to give their respective outputs. The cells give the current and voltage as output whereas the phototubes work on the low range of radiations and give other electrical signals.
(d)
Interpretation:
The difference between the use of the photodiodes and the photomultiuplier tubes is to be explained.
Concept introduction:
The photodiodes as well as the photomultiplier tubes both make use of the light signals incident on them and produce the required electric signal as per their use.
(e)
Interpretation:
The difference between use of the double beam in space and double beam in time spectrophotometers is to be explained.
Concept introduction:
The both spectrophotometers make use of the two beams from the source and these beams are divided and transmitted by using a beam splitter.
(f)
Interpretation:
The difference between the spectrophotometers and the photometers is to be explained.
Concept introduction:
The photometers and the spectrophotometer are used to determine the spectrum of the radiations, and they are different from each other in terms of wavelength selector used in them.
(g)
Interpretation:
The difference between the single beam and double beam instruments for absorbance measurements is to be explained.
Concept introduction:
The single beam and double beam instruments for absorbance measurements make use of the intensity of the light to measure the absorbance.The double beam instrument makes use of the two beams whereas the single beam make use of single beam.
(h)
Interpretation:
The difference between the conventional and the multichannel spectrophotometers is to be explained.
Concept introduction:
The multichannel spectrophotometers take only a second to record the full spectrum, whereas, the conventional spectrophotometers may take even minutes to record a single spectrum.
