The diffraction grating and the difference between the two types of gratings.
Answer to Problem 1ASA
The diffraction grating and the difference between the two types of gratings are defined as below.
Explanation of Solution
The diffraction of light waves is associated with deviation or bending of light waves through the surfaces with sharp edges that splits the light wave into several beams which travel in different direction.
Therefore, the diffraction grating is an optical component that have a periodic structure and is made up on a metal piece or a glass, with large number of finely divided parallel lines, known as slits of the grating which is responsible for the diffraction of the light to give rise to an interference pattern.
Generally a diffraction grating is of two types: Reflection gratings and transmission gratings. The reflection gratings are those diffraction gratings which is made up on a metal piece and light is allowed to diffract from a ruled polished metal surface and light is reflected from the unruled surface.
While, the transmission gratings are those diffraction gratings which is made up on the glass and the incident light is allowed to transmit from the surface through the unruled slit areas. So the difference between the two type of the grating is that the reflection grating can diffract as well as reflect the light waves from the grating surface. However, the transmission gratings can diffract the light waves and tranmit the light further, which can be used in experiments for study of the spectrum.
Conclusion:
Thus, the diffraction grating and the difference between the two types of gratings are defined as above.

- If a beam of white light passes through a diffraction grating with vertical lines, the light is dispersed into rainbow colors on the right and left.
