Diffraction grating practical lab: Practice Quiz
If you use this practice test please share your experience through the comment box below. So I can prepare for other experiments too if it is beneficial for you all.
Viva Questions Determine the wavelength of the laser light by diffraction grating and demonstration.
In the above video, you can watch the demonstration of the experiment includes the diffraction grating practical lab. The grating is a glass slab that may have a number of lines known as grating elements. You may have noticed the text on the glass slab, i.e., 15000 LPI. It means 15000 thousand lines per inch.
How to perform diffraction grating practical lab
You know that in one inch is equal to 2.54 cm. So if you have to determine the grating element then you have to solve it mathematically. You can perform a diffraction grating practical lab with any laser.
