632.8 nm) is used to calibrate a diffraction grating. If the first-order maximum occurs at 21.0°, what is the spacing between adjacent grooves in the grating? (In this problem, assume that the light is incident normally on the grating.) μm A helium-neon laser (1 =

Using monochromatic light, an interference pattern is generated on a screen 50.0 cm away from a double slit. The width of the slit is 12 μm.  The third dark fringe is 6.0 cm from the center of the central maximum. What is the wavelength of the light used in nanometres?

A double-slit experiment is used to calculate the wavelength of a light source. The first order maximum in the interference pattern occurs 7.1 cm from the screen center, slit spacing is measured to be 15μm and the distance between slit and screen is 2.2 m. Estimate the wavelength of the source used.
