an arragement of very large no. of narrow slits of equal width placed side by side and seprated by equal opaque portion is known diffraction grating.when wavefront is incident on grating surface then light is obstructed by opaque portion and is transmitted by slit,such a grating is called plane transmission grating.in general it is constructed by ruling equidistant parallel line by diamond point on glass surface.

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 diffreance between transmission grating and diffraction grating?
Diffraction gratings can be categorized into 2 types - reflection gratings and transmission gratings. So, transmission gratings are a subset of diffraction gratings. Kristian Buchwald, Ibsen Photonics
What do you mean by transmission?
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.

How many types of diffraction grating are there?
There are typically two main types of diffraction gratings: transmission gratings, which allow light to pass through the grating material, and reflection gratings, where light is reflected off the surface of the grating. Both types can be further categorized based on the method used to create the grating, such as holographic, ruled, or blazed gratings.
Why sodium lamp is not used in transmission grating?
Sodium lamps emit light at specific wavelengths that may not be suitable for the transmission grating efficiency curve, leading to poor performance. Additionally, the low-intensity output of sodium lamps may not provide enough light for accurate spectroscopic measurements that typically require a light source with higher intensity levels. Lastly, sodium lamps can be prone to fluctuations and instability, which can complicate the spectroscopic analysis when using a transmission grating.

What will happen if mercury lamp is used instead of sodium lamp in plane diffraction grating exp?
Using a mercury lamp instead of a sodium lamp in a plane diffraction grating experiment might result in a different wavelength of light being emitted. This would affect the interference pattern observed on the screen, leading to a shift in the position of the fringes. Additionally, the intensity of the light and the overall visibility of the interference pattern might also be altered.
Is fiberglass grating better than metal grating?
Metal grating will generally be more durable and trouble free. I would not suggest fiberglass for a good grating material.
What is the grating constant for a 600 lines per mm diffraction grating?
The grating constant for a diffraction grating is the inverse of the lines per unit length. Therefore, for a 600 lines per mm grating, the grating constant would be 1/600 mm or approximately 0.00167 mm.
