Question

What is the difference between longitudinal dihedral and wing dihedral?

Answer 1

Longitudinal dihedral is the angle of attack or attitude of the wing in relation to the aircraft's longitudinal axis as it moves through the air.

Most aircraft wings are raised a very minute amount at the leading edge giving them longitudinal dihedral.

Wing Dihedral is the angle of the wings from horizontal.

Most aircraft wings form a shallow v when viewed from front or back.  This gives the aircraft stability when rolling into a turn.  Dihedral does however have an adverse effect on roll rate slowing the planes ability to make quick manuvers.
