Transcribed Image Text:9. (Advanced) The illustration in Question 8 shows diffraction in first order. Change the wavelength so
that the illustration shows diffraction in second order.
Transcribed Image Text:8. (Advanced) The derivation of the diffraction equation
depends on matching wave crests along the grating surface
with openings in the grating. In the diagram at the right,
the arrows indicate ray directions and the dashed lines are
wave crests. Add a surface-normal line to the diagram and
mark the diffracted angle on the diagram. Also sketch the
right triangle sharing a hypotenuse with the grating spacing
that can be used to derive the diffraction equation.
