Determine the angle for the first order maximum of a 12,000 lines/cm diffraction grating and light wavelength at 550 nm

Explanation:

Given that,

Number of lines,

Wavelength,

We need to find the angle for the first order maximum, n = 1

Using the grating equation as :

So, the angle for the first order maximum is 41.29 degrees. Hence, this is the required solution.
