diffraction grating is a lik a plate on which many slits are present....light undergoes diffraction through the slits...diffraction grating then splits light into its conctituent colours which appear with spaces between them..

∙ 13y agoDiffraction gratings have many uses. Some of their uses include: spectrometers (devices which measure properties of light), monochromators (devices which only transmit rather narrow ranges of wavelengths of EM radiation chosen from sources which provide a greater range of wavelengths), but also fibre optic communication (wavelength division multiplexing, to be more specific, which allows different wavelengths of light to carry different signals over a single strand of the optical fibre), lasers and many more other things

How do you determine wavelength of source in diffraction grating?
In diffraction grating we use the expression N m L = sin @ Here N is the number of line per meter length in the gartin. m the order (1,2,3) L- lambda which stands for the wavelength of monochromatic light used to perform experiment And @ is the angle of diffraction for which we get maximum
What is the grating constant for a 600 lines per mm diffraction grating?
1.667
How can you tell what sort of gas is emitting light?
Diffract the light you see with a diffraction grating (a transparent material with microscopic lines cut into it). Each element has a distinctive pattern of bands of color when viewed through a diffraction grating. Compare what you see with known color patterns, keeping in mind that you could be viewing multiple elements.
Velocity of ultrasonic wave using acoustic grating?
The ultrasonic waves generated with the help of a quartz crystal inside the liquid in a container sets up standing wave pattern consisting of nodes and anti-nodes. The nodes are transparent and anti-nodes are opaque to the incident light. In effect the nodes and anti-nodes are acts like grating(a setup of large number of slits of equal distance) similar to that of rulings in diffraction grating. It is called as acoustic grating or aqua grating. Hence, by using the condition for diffraction, we can find the wavelength of ultrasound and thereby the velocity of sound in the liquid medium.
Is the first order spectra wider than the second order spectra in a diffraction grating experiment?
NO. Recall sin@ = N m L. Here N is number of slits per unit length, m the order and L (lambda) the wavelength of light. As m = 2 then @ for different colours would be larger and so wider
What are Precautions and sources of error of diffraction grating experiment?
taking the measurements
What kind of laser is used in diffraction grating experiment?
laser is not used in that experiment. that was mercury lamp which is used for that exp.
Is diffraction grating is used in polarization?
No diffraction grating is not used in polarization.
Why cant you see red colour in diffraction grating experiment?
as red light refracts at bigger angle we cant see it
Why does a diffraction grating will separate while light into colors?
A diffraction grating does not disperse light into its component colors. However, a prism does. A diffraction grating simply causes light to diffract and display an interference pattern on a screen.
How do you determine wavelength of source in diffraction grating?
In diffraction grating we use the expression N m L = sin @ Here N is the number of line per meter length in the gartin. m the order (1,2,3) L- lambda which stands for the wavelength of monochromatic light used to perform experiment And @ is the angle of diffraction for which we get maximum
What is the grating constant for a 600 lines per mm diffraction grating?
1.667
What will happen if mercury lamp is used instead of sodium lamp in plane diffraction grating exp?
for diffraction grating mercury lamp is used not sodium lamp.
Where to buy diffraction grating?
Try Edmund Scientific
What can a diffraction grating be used for?
measuring wavelengths of light
Role of the diffraction grating in the spectroscope?
spectroscope and its roles
How diffraction grating could be used as the dispersive element?
Diffraction grating could be used as the dispersive element because of the ability of light to be broken according to various wavelength.
