yes this is an impotent method for focusing the spectrometer in-order to obtain the appropriate readings.
None.The mean of a single number is itself.Therefore deviation from the mean = 0Therefore absolute deviation = 0Therefore mean absolute deviation = 0None.The mean of a single number is itself.Therefore deviation from the mean = 0Therefore absolute deviation = 0Therefore mean absolute deviation = 0None.The mean of a single number is itself.Therefore deviation from the mean = 0Therefore absolute deviation = 0Therefore mean absolute deviation = 0None.The mean of a single number is itself.Therefore deviation from the mean = 0Therefore absolute deviation = 0Therefore mean absolute deviation = 0
The mean average deviation is the same as the mean deviation (or the average deviation) and they are, by definition, 0.
No. The mean deviation is 0. Always.
It is named after the type of prism used in the instrument. A constant deviation prism has the property that the angle between light entering the prism (the incident light) and light exiting the prism (the emergent light) is always the same, no matter what the angle of the incident light to the prism.

difference between ordinary prism and constant deviation prism
By keeping the prism in minimum deviation position, the RI of the prism can be calculated efficiently.

construction of spectrometer?
spectrometer spectrometer
Constant size & shape.
The mechanical advantage is a numerical relationship among the sizes of physical components of the machine. It's constant as long as the sizes of those parts of the machine are constant.
we use mercury lamp instead of ordinary lamp because ordinary lamp has many wavelengths when mercury lamp has single wavelength so in constant deviation we use only mercury lamp.
spectometer is an instrument wnich measures the light passes through a prism
It means that equilibrium may be attained at widely separated values.
