See this link.What_is_the_difference_between_ordinary_prism_and_constant_deviation_prism
An ordinary prism disperses light based on varying angles of refraction, resulting in different colors being separated at different angles. A constant deviation prism disperses light in such a way that all colors are dispersed at a constant angle, maintaining a consistent level of separation irrespective of wavelength.
Ordinary constant is a real constant which is same in all time but arbitrary constant is not constant at all time intervals, especially we can see arbitrary constants in integrals.For example the anti derivative of x+C is 1. Here we can replace C with any constant so C is arbitrary constant

absolute deviation is a difference between say two numbers. The result has the same units as the two numbers have. Relative deviation is a ratio and so it is a pure number without any units.
Difference between the actual and planned for a effort is known as effort deviation.
EXTRA!!
The difference between a tied grant and an ordinary grant is that a tied grant has conditions and the ordinary grants don't!
The mean is the average value and the standard deviation is the variation from the mean value.
There is no difference between them they are same rate constant is another name of specific rate constant
tracheal deviation
the difference between a constant in a graph and a constant in a experiment is that when on a graph, the constant is the thing that changes, and in a experiment it is the part that stays the same.
