@resonancefeel

In fact number of lines per inch will be given on the grating. From the LPI we are going to find the grating constant d, this is nothing but the distance between two lines or one inch devided by number of lines. If it is not given on the grating then we have to find it (distance between two lines). We need the travelling microscope or comparator microscope to find the distance. Thank you

Hi there, There is no need of plotting the graph. Graph is only to mark the laser spots falling on screen. Even you can use a blank paper for spots marking. OR If you want to calculate the wavelength by plotting the graph only then one can plot the graph of "d sin(theta) Vs n" and find the slop which gives the wavelength.

Hello, If number of lines increases per inch or per cm means decrease in d value. We have Lambda = d sin theta/n If theta increases spacing between points on screen increases. Since d and theta are inversely proportional from above formula, "If d decreases (increase in lines) then spacing between points (theta) increases"

Normally more points will appear, centre point maxima and intensity diminishes centre to either sides. Distance between points is more because of following reason.

Since d and theta are inversely proportional from above formula, "If d decreases (increase in lines) then spacing between points (theta) increases"
