Am. J. Phys., vol. 33, pp. 922--923, (1965).
Abstract: A simple lecture demonstration is described, in which light
from a gas-discharge laser isdiffracted at grazing incidence by the
rulings of a steel scale. The wavelength of light isobtained by
measuring the pattern spacings and the distance from the ruler to the
screen.

Abstract
Almost 20 years ago, Arthur L. Schawlow, the 1981 Nobel laureate, told
the author that a metal ruler could be used to measure the wavelength of
light. Since then, he has always wanted to verify the accuracy of such
an experiment for himself. He finally has; the method and results are
reported in this article.
