Right, that's the ambiguity that needed addressing, we'll in that case because this is a equilateral triangle the incident angle of the light on the interior of the prism should be equal the incoming angle being subtracted from the axis normal to the prism surface. The reference of 45 degrees...

Homework Statement white light propagating in air is incident at 45 degrees on an equilateral prism Find the angular dispersion "gamma" of the outgoing beam if the prism has refractive indices n(red) = 1.582 and n(violet) = 1.633. NOTE: "gamma" is just a variable for describing the angular...

Ok, thanks that makes sense. The answer I got basically said that all the tension in the wires is in the negative y direction because the x direction components are pointing opposite and cancel out. This problem is done.

[b]1. A 10 Kg painting is hung with a wire supported by two nails. The length of the wire is 1.3m. A) what is the tension in the wire? B) what is the magnitude of the force exerted on each nail by the wire (assume that the tension is the same in each part of the wire). In the diagram you...
