What is Prism Spectra?

Prism spectra are the continuous spectra we can get using a prism. A prism is a transparent instrument that is triangular and has a refracting medium that can cause the refraction of light. It has a base and an apex, and its apical angle tends to determine the diprotic power of the material. When light passes through a prism, the light gets dispersed by it, giving a prism spectrum.

可见光通常是白光，其中包含一系列组成颜色。通常，当光穿过三角形棱镜时，我们可以观察到这些颜色。这是因为当光穿过棱镜时，白光将其分离成其成分颜色。我们可以观察到的颜色成分是红色，橙色，黄色，绿色，蓝色和紫罗兰色。通常，这种颜色分离过程称为分散。

颜色的光的色散可以描述d based on the varying frequencies and wavelengths of each colour component. These different frequencies of light tend to bend in varying amounts as the light passes through the prism.

When considering the material of the prism, different materials have different optical densities (the optical density is the tendency of a material to slow down the light when the light passes through that material). When light is passing through a transparent material, it tends to interact with the atoms of the material. If the frequency of the light wave matches the resonance frequency of the electrons in atoms, the light is absorbed by that atom. The unabsorbed light comes out of the prism, which gives us the prism spectrum.

What is Grating Spectra?

Grating spectra is the spectra we can obtain from grating prisms. These spectra appear as line spectra, and they form due to the diffraction of light. This technique is very important in analyzing light sources. A grating spectrum contains a large number of equally spaced parallel slits. The basic phenomenon of the working principle of the grating spectra is light diffraction. There are spaces between lines of this spectrum that appears as slits; these slits diffract the light waves, producing many different beams that can interfere to produce a spectrum.

A grating prism or grism can be explained as a combination of a prism and a grating system that is arranged along with prims, which allows the light of a chosen wavelength to pass through the prism straightly. This prism system has the advantage of allowing a single camera to be used for imaging and spectroscopic needs without removing or changing the prism.

What is the Difference Between Prism Spectra and Grating Spectra?

棱镜光谱和光谱光谱是两种不同类型的光谱，它们彼此不同，主要是在形成的方式上。The key difference between prism spectra and grating spectra is that, in prism spectra, the spectrum is created due to the dispersion of light, whereas in grating spectra, the spectrum is created due to the diffraction of light. Moreover, prism spectra give acontinuous spectrum, whereas grating spectra give a线光谱。
