It has been clear to you know.Thank you Stuti Dhapola for feedback….yes I will try to cover some more experiments.Good questions.. looking forward for more on different topics and experiments as per the present bsc. The equation is lambda = (a * x) / d, where 'lambda' is the wavelength in meters, 'a' is the distance between the slits in the diffraction grating, 'x' is the fringe separation, and 'd' is the distance between the screen and the grating. grating element will be=1 inch/15000This is standard value which we can determine by the formulaLight Amplification of Spontaneous Emission by RadiationLight Amplification by Stimulated Emission of RadiationWhy do you use n lembda= d sin theta formula?

What happens when light hits a hard surface? The difference between the measured and expected was between 4% and 10%.
These are maximum and minimum wavelengths which are indicated on the lasers themselves, so I knew approximately what the wavelength should be to see if I got the right answer.Looking at the calculations, my measurements do not lie within the maximum and minimum bounds but they are at least consistent.
To do this follow this method:(You'll notice that there is a discrepancy between the picture and what I have recorded in my results later. Maimon’s first laser used ruby (CrAlO3) to produce red light beam with a wavelength of 694 nm. 1 year ago The symbol for wavelength is the Greek lambda λ, so λ = v/f. 1 year ago How to perform laser wavelength by diffraction grating in practical labIt is the interaction between two or more waves of the same or close frequencies emitted by the Coherent sources. premium As per the formula of wavelength of light, \(\lambda =\frac{\nu }{f}\\ \\ \Rightarrow \lambda =\frac{3\times 10^{8}}10{6.24\times 10^{14}}\\ \\ \Rightarrow \lambda = 4.80\times 10^{-7}\) Also, learn the difference between violet and purple . Kids see diffraction and the inverse square law of light in action with this great science fair project idea. Wavelength usually is expressed in units of meters. A device which is helpful to take the readings in this experiment.An optical instrument or device which have several parallel lines. Practised using the grating formula. How does distance affect the spreading of light? The longest wavelengths, from 700 nm to 1 mm, produce infrared (IR) light which, like UV, is invisible to the human eye.Maimon’s first laser used ruby (CrAlO3) to produce red light beam with a wavelength of 694 nm. If your science savy third grader is up for a challenge, let her bend light with a casserole dish!
You can perform a diffraction grating practical lab with any laser.You will learn that what are the applications of diffraction grating and about to the plane diffraction grating.

Thanks, I had a lot of fun doing this. 5th grade
