joules constant
They both have sides that are rectangular in shape. They both have a constant cross-sectional shape equal to the shape of the ends (triangle for a triangular prism; rectangle for a rectangular prism).
If you mean prism, the answer is YES. If you meant prim, I have no idea.
A hexagonal cylinder is an impossible object. If you meant a hexagonal prism then it is a polyhedron.
difference between ordinary prism and constant deviation prism
See this link.What_is_the_difference_between_ordinary_prism_and_constant_deviation_prism
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.
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.

Assuming that pirsim is meant to be prism, the answer is that a triangular based prism has triangular bases!
A triangular prism is one with two triangles as the bases and 3 corresponding parallelograms as faces. The triangular prism is also a prismatic uniform polyhedron.
They both have sides that are rectangular in shape. They both have a constant cross-sectional shape equal to the shape of the ends (triangle for a triangular prism; rectangle for a rectangular prism).
the dispersive power of prism can be defined as the rate of change of angle of deviation in specific spectrum of light ..
A prism *always* has 2 bases. In case you meant "faces" instead of "bases", the prism with the smallest number of faces is the triangular prism - which has 5 faces. If there were any fewer number of faces, the prism which become a two dimensional object.
