Diffraction Grating Handbook Chapter 1 lines emitted by the source. This explains why systems with revolving powers greater than 500, 000 are usually required only in the study of spectral line shapes, Zeeman effects, and line shifts, and are not needed for separating The grooves of a compact disc can act as a grating and produce iridescent reflections.
Diffraction gratings are often used in monochromators, spectrometers, lasers, wavelength division multiplexing devices, " Diffraction Grating Handbook" (7th ed. ). Richardson Gratings. Orientation of the grating grooves (tilt adjustment) 247 Diffraction Grating Handbook was the primary source of information of a general nature regarding wrote the Observe diffraction of light waves through a CD and DVD CDs and DVDs are well know to students so they are likely to be interested in the lab and participate in discussion Easy to transition into a discussion about current technology and trends involving CD grating.
Laser. Screwdriver CD spectroscope is built with a screwdriver that has a round bright shaft and a piece of CD that has its label removed. The CD is mounted in a tube.
The screwdriver round bright shaft is used as the slit to reflect a sliver of light towards the CD. It is this narrow spacing that is responsible for the wonderful colours reflected by a CD which works just as a diffraction grating.
Consider a small part of a CD (see the sketch) with light shining perpendicularly down on its surface: So all the grooves are illuminated by the incoming light wave at the same time. CD Diffraction Grating of known slit spacing Mounting assembly Some sheets of white paper.

4. diffraction gratings from newport 18 2. the physics of diffraction gratings 20 I can add to the previous answer that in some cases DVD or CD disks without any modification can be used as a diffraction grating.
In our university it is often used for studentical laboratory works. Features a 13, 500 lineinch diffraction grating.
