“Light enters the mouse through side openings near the front and travels to a reflective diffraction grating.”

“In our fluorimeter, monochromatic light is produced by passing white light through a diffraction grating.”

“It was a beautifully worked out theory and explained most of the observed phenomena of light such as reflection, refraction, diffraction etc.”

“The diffraction constant for the diffractometer was calculated using a grating with 0.1 turn spacings.”

“The specimens were then ground to a fine powder and analyzed individually in an X-ray diffractometer to determine carbonate polymorph mineralogy.”

“The NRC diffractometer calibrates the average line spacing with an uncertainty much less than the distance between atoms.”
