Question

A hole is made in an opaque sheet of paper. A monochromatic variety of light is shot at the paper from one side. On the opposite side of the paper, the effects of diffraction will be greatest when the light has a _______ and the hole is _______. A. long wavelength; small B. high frequency; small C. low frequency; large D. short wavelength; large

Answer 1

A. long wavelength; small

Diffraction is the greatest whenever the gap where the wave is passing through is smaller. This gap property will make the wave to "curve" reaching a more wider area, the smallest the gap is, more the wave will curve, spreading more widely. The light would propagate more rather then being concentrated on one focus. The wavelength is also something that affects diffraction. Whenever the wavelength is longer, the wave will have more time to spread sideways after diffraction.
