In optics, a diffraction grating is an optical component with a periodic structure, which splits and diffracts light into several beams travelling in different directions. The emerging coloration is a form of structural coloration. The directions of these beams depend on the spacing of the grating and the wavelength of the light so that the grating acts as the dispersive element. Because of this, gratings are commonly used in monochromators and spectrometers.

For practical applications, gratings generally have ridges or rulings on their sur ....etc

engineering physics lab viva questions with answers

1. What is semi conductor diode laser?
Semiconductor diode laser is a specially fabricated pn junction diode. It emits laser light when it is
forward biased.

2. What is LASER?
The term LASER stands for Light Amplification by Stimulated Emission of Radiation. It is a device
which produces a powerful, monochromatic collimated beam of light in which the waves are coherent.

3. What are the characteristic of laser radiation?
Laser radiations have high intensity, high coherence, high monochoromat ....etc

So that s it. For now we have collected this much of Lab Manuals and lab books. We are still preparing the remaining lab manuals which we could not upload till now. It will be updated within next few weeks. As we said earlier, this collection is quite new and we are making new section for it. So there might be dead links or misplaced resources. You are requested to report the same if you find any error. We would love to hear from you and rectify the problems. Also comment the name of the subjects below which we have missed to upload here for n ....etc
