6. Electromagnetic radiation passes through a single slit with a width of 1 um. Determine the angular full-width of the central diffraction peak (i.e. the angle between the first minimum on one side of the slit to the first minimum on the other side of the slit) for:
(a) Visible light with a wavelength of = 550 nm
(b) X-rays with a wavelength of = 0.15 nm
(c) Which of these more clearly demonstrates a wave-like nature?
(Remember: diffraction from a single slit is different from that of a double slit, so think
carefully about the condition for constructive/destructive interference)
