Diffraction Flashcards

Flashcards about diffraction using lecture notes.

What type of pattern is produced by single-slit diffraction of coherent light?

A wide central band with narrower bands on either side.

When light passes through a single slit, what appears?

A bright central band, with dimmer, narrower bands to the side.

Monochromatic light passing through a single slit will produce a diffraction pattern __ a double slit.

Different from

In single-slit diffraction, what is analyzed when determining wavelength from the experiment?

In single-slit diffraction, the angles between dark bands are analyzed when determining wavelength from the experiment.

What causes a diffraction grating to produce interference patterns?

Tiny scratches that act like slits.

Diffraction gratings have large numbers of closely spaced slits to _.

Increase the intensity of the diffraction pattern and produce sharp images.

600 slits/mm

Which number of slits in a diffraction grating produces the narrowest lines?

Which of the following changes would increase the separation between the bright fringes in the diffraction pattern formed by a diffraction grating?

Increase the wavelength of the light used.

If light passes through a 0.050 mm slit and is projected on a screen 0.70 m away with 8.0 mm between the central bright band and the first dark band, what is the wavelength of the light?
