In this experiment, you determine the laser wavelength by a diffraction grating. To provide all physical concepts associated with this experiment I have created this quiz. You can attempt it and learn more about the experiment.
In the above video, you can watch the demonstration of the experiment including 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.
viva questions on diffraction grating pdf download
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.
In the quiz that is given below, there are many diffraction grating experiment viva questions that will help you to understand this phenomenon and its applications. what is a grating element? if this is your question. It has been clear to you know.
This is an lesson about spectrographs. Learners will build and decorate their own spectrographs using simple materials and holographic diffraction gratings. After building the spectrographs, they observe the spectra of different light sources. Requires advance preparation to spray-paint the inside of the containers black the day before construction. The activity is part of Project Spectra, a science and engineering program for middle-high school students, focusing on how light is used to explore the Solar System. 2ff7e9595c
