    As shown above, two beams of laser light are shown onto two different pieces of plastic. The two beams both have a wavelength of λ = 630 nm and start out in phase 2.5 m to the left of the plastic pieces. The top piece, #1, has an index of refraction of 1.26 and a thickness of 3.2 μm. The bottom piece, #2, has an index of refraction of 1.44 and a thickness of 2.8 μm. The beams continue on and shine on a wall 2.2 m to the right.

    Expressed in terms of wavelengths, what is their phase difference when they both have emerged from the plastic?

  • Math help!!!?

    Let Line 1:

    x = 2-2t, y = 4t, z = 1-t

    and Line 2:

    x = s, y = 3 -3s, z = 1

    a) Verify that the lines are skew lines. (i.e., show that they do not intersect and are not parallel).

    b) Find the equations of the parallel planes through each line.

    I understand part a, i need help with part b
