what is meant by grating
Fiberglass grating is made to look similar to metal grates in industral use, but since it is made of fiberglass it is corrosion and impact resistant. Fiberglass grating has low electric and heat conductivity and can be made strong enough for fork lifts or even trucks to travel over.
bacause the spectrum means spectrum so the spectrum is known as spectrum is called as spectrum
Whether you are preparing a construction site for activity, or laying down a permanent walking space in a location where there is a safety concern, you will find fiberglass grating to be a professional, affordable solution to walkway construction. When installing grating, concern is usually focused on three factors: safety, appearance, and affordibility. Fiberglass grating provides a superior solution in all of these areas, with results that are guaranteed to impress, whether the person you are impressing is your boss, your customer, or the public. Fiberglass grating offers a number of strategic advantages over other methods of laying down walkway flooring. Because it is manufactured from fiberglass instead of a heavier material such as metal, it is much more lightweight, making it suitable in conditions where the overall weight of an assembly is a critical factor. The fiberglass material also makes this style of grating extremely easy to install. The material is easy to fabricate to fit in oddly shaped areas, as well. The strength of the fiberglass ensures that the overall stability of the grating is not compromised when an assembled grate is fabricated to fit a shape. It also ensures that the walkway that you are laying down will remain durable and strong for years after it is installed. The physical properties of fiberglass also make it an optimal material to use in the construction of walkway grating. It has low conductivity, making it a much safer surface to be caught standing on in risky electrical situations such as lightning than other material such as metal. It has highly rated strength in impact and fatigue testing, and its durability means that maintenance of the structure is simple and cost-effective. Cracking and chipping are not concerns when installing fiberglass grating, as the material is resistant to the types of high impact activity that causes such damage to less rigid materials. No matter what your needs for walkway grating are, fiberglass grating provides a safe, resilient, durable alternative to other types of grating. Fiberglass grating is up to whatever challenges you throw at it. Try fiberglass grating - you will definitely be pleased with the results.
A portcullis is "a grating of iron hung over the gateway of a fortified place and lowered between grooves to prevent passage."
It's called a "portcullis"
Grating spectrum is a spectrum produced as a result of diffraction, as by a grating.Whereas prismatic spectrum is a consequence of dispersion of light by a prism. In grating spectrum you also observe different orders of spectral lines which does not happen in prismatic spectrum. Hope this helps VIBHAV ZUTSHI B.Tech '13 IIT Kharagpur
Prism spectrum is formed due to DISPERSION but grating spectrum is formed due to DIFFRACTION. In prism spectrum we have only one order but in grating spectrum we can have second order too IN prism spectrum we have continuous spectrum but in gratings we have only line spectrum In prism spectrum red end will be closer to the direct ray but in grating spectrum violet end will be closer to the direct ray
You can split white light using a prism or a diffraction grating.
A prism, a diffraction grating, a water droplet, etc.
A prism typically produces a more intense spectrum than a grating because it does not disperse the light as much, leading to higher light concentration on each wavelength. Additionally, prisms typically have higher efficiency compared to gratings in separating light into its spectral components, further contributing to the intensity of the spectrum produced.
Grating.
A diffraction grating separates white light into its component colors by bending and spreading the light waves. This creates a spectrum of colors, similar to a rainbow.
A diffraction grating is a simple device that uses diffraction to produce a better spectrum than a prism. Diffraction gratings consist of closely spaced parallel slits or grooves that cause light to diffract at different angles, resulting in a more detailed and accurate spectrum compared to a prism.
A diffraction grating does.
The colors in the emission spectrum of sunlight range from violet to red. This spectrum is created by the various wavelengths of light emitted by the sun, and can be seen when sunlight is passed through a prism or diffraction grating, creating a rainbow of colors.
The colors of the spectrum can be shown in an experiment using a prism or diffraction grating to separate white light into its component colors. When white light is passed through the prism or grating, it bends and disperses, creating a rainbow of colors known as the spectrum. Each color corresponds to a different wavelength of light.
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.
