### Diffraction Grating Experiment: measuring wavelength | A ...

To standardise the grating: Turn the telescope to obtain the image of the slit. Turn the telescope to both sides to obtain green lines.Note the reading of both the verniers. Calculate the difference in the reading to obtain the diffraction angle. Then from the equation, number of lines per unit length of the grating can be calculated.

### How to Find LASER Wavelength Using a Diffraction Grating ...

Jan 27, 2017· This you can find out from the lines that are mentioned on the grating as here 15000 LPI. One inch is 2.54 cm so 15,000 lines are in 2.54 cm so one line will be equal to 2.54/15000 cm. This is 1.69×10^ (-4)cm approximately. We have to use nk=2d sin theta. where k is the wavelength; that is to be found from observation.
