What kind of pattern of light would you get if you shone monochromatic light on a diffraction grating?
If you shone monochromatic light on a diffraction grating it would alternate bright and dark bands. Only white light white light shone through a diffraction grating would produce a band of colors.
What do you mean by diffraction?
• DIFFRACTIONDIFFRACTION has 1meaning:When light passes sharp edges or goes through narrow slits the rays are deflected and produce fringes of light and dark bands
What do you mean by transmission grating?
Grating is nothing but having many parallel slits or parallel reflectors. If slits are there then light could pass through and so it is named as transmission grating. Otherwise in case of reflection it is termed as reflecting grating. Any way in both the case diffraction phenomenon takes place.
Why does light produce a pattern similar to an interference pattern when it passes through a single slit?
This phenomenon occurs due to light's wave-like properties. Via diffraction, the bending of light wave about an obstacle, the light wave will interfere and exhibit dark and bright fringes on a screen as a result of this interference.
How does diffraction grating create a spectrum?
Let's make certain we are on the same page first. A diffraction grating is an apparatus (piece of plastic, glass, ceramic) that has anywhere from one to ten thousand (or more!) thin grooves cut into it. The grooves act as slits that allow light to pass through the grating at regular intervals. In order to produce a decent diffraction pattern (often called interference fringes), the light must be coherent; that is, the light waves coming from the source must be in phase, containing waves vibrating in the same manner (i.e. rising to a crest and falling to a trough at the same points). When monochromatic coherent light (think laser light) strikes a diffraction grating, the light spreads out past the slits and shines onto a screen. When the light passes through the slits, some light rays travel straight through, but others travel at an angle away from the slits. When the angled light rays meet other light rays, they interfere and produce either bright spots (antinodes) or dark spots (nodes). If the interfering light rays are in phase, the rays interfere constructively, and the spots are bright; but, due to destructive interference, the spots are dark if the interfering rays are out of phase. With monochromatic light, the diffraction pattern is a series of bright spots separated by dark bands. For instance, if we shone a green laser through a diffraction grating in a dark room, we would see green spots alternating with black bands. The process is the same for composite light, but the results are a little different. White light is called a composite light because it is composed of six basic colors: redo, orange, yellow, green, blue, and violet. Colors of light are our perception of light waves' frequencies. Since these different colors of light have different frequencies, they also have different wavelengths, and waves with different wavelengths diffract differently. You might remember that longer wavelengths (red light) refract less than short wavelengths (violet light). This pattern is reversed for diffraction: of all the colors of the visible spectrum, red diffracts the most, and violet diffracts the least. Therefore, when white light is shone through a diffraction grating in a dark room, the light waves still spread out past the slits just as monochromatic light does; however, the red light angles away from a slit more than any other color of light, and the violet light angles away the least. The other colors of the visible spectrum fill in the intervening space, and pow!--you have a spectrum! In fact, you should have at least two visible spectra, one on either side of a bright white spot, separated from the white spot by black bands.

What is the definition of diffraction grating?
A diffraction grating is a device that consists of a series of closely spaced parallel slits or rulings used to separate light into its individual wavelengths. When light passes through a grating, it is diffracted, producing a pattern of spectral lines that can be used for spectroscopy or other analytical purposes.
What do you mean by transmission grating?
Grating is nothing but having many parallel slits or parallel reflectors. If slits are there then light could pass through and so it is named as transmission grating. Otherwise in case of reflection it is termed as reflecting grating. Any way in both the case diffraction phenomenon takes place.
What is spectometer in physics?
It is an optical device to study about the spectrum produced by the refraction phenomenon through a triangular prism or obtained by the diffraction phenomenon at the grating.
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.

What is a plane transmission diffraction grating?
A diffractiongrating is an optical device consisting of many closely spaced parallellines or grooves. In a transmission type of grating, lightpasses through the narrow transparent slits that lie between the dark lines on a glassor plastic plate.
What is Diffraction grating experiment?
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..

When a moves through an opening in a barrier it?
Bends and spreads out.When waves of any kind, sound, light electromagnetic radiation hit a gap in a barrier that is on the same scale as the wavelength then diffraction will occur. Diffraction is the bending of the wave and this appears as circular waves when we observe this effect with water.A common diffraction grating can be seen on a CD or DVD. The light spreads and we see this as different colours.
