Diffraction Gratings
Introduction to Diffraction Gratings:
Grating is a device used to find the diffraction of light. The property of bending of light rays at the edges of an obstacle or slit is called DIFFRACTION. To observe the diffraction pattern the necessary condition is that the size of the aperture must be approximately equal to the wavelength of light.
Grating consists of a large number of parallel slits separated by opaque distances. The width of each slit is approximately equal to wavelength of light. Basically there are two types of gratings, namely transmission grating and reflection grating. Understanding Emp Electromagnetic Pulse is always challenging for me but thanks to all math help websites to help me out.
Transmission grating can be prepared by drawing a large number of parallel lines using a diamond point, on a transparent medium. The line drawn acts as opaque to light and the distance between each line is transparent to light.
Reflection grating can be prepared by drawing a large number of parallel lines using a diamond point, on an opaque medium. The line drawn acts as transparent to light and the distance between each line is opaque to light.Please express your views of this topic formula for ionic compounds by commenting on blog.
Experiment on Diffraction Gratings
When a white light incidents on a DIFFRACTION GRATING, light is diffracted in various direction at various angles. Diffraction pattern consists of spectra of various colors in different orders. If 'e' is the width of the slid and 'd' is the distance between the slits then the equation which explains the grating spectra is
(e+d) sin θ = ± n λ ................... (1)
Here 'n' is represents the order of the spectrum and
'λ' is the wavelength of light or color.
'θ' is the angle of diffraction.
From equation (1)
1. In a particular order (n - constant), the angle of diffraction is proportional to the wavelength of the color.
2. For a particular wavelength (λ - constant), the angle of diffraction is proportional to order of the spectrum.
Hence when white light incidents on grating, In particular order (n - constant), Violet color is less diffracted and Red color is most diffracted.
'±' indicates that the spectra of color appears on either of the central image (Direct ray).
