(we usually use "n", not "m")
it can be any whole number …
there may be more than one value for which there is a solution

what do you get?
A diffraction grating is a device that contains a large number of parallel, equally spaced slits or grooves that are used to separate light into its component wavelengths. It works by causing interference patterns of light, resulting in a spectrum of colors.
The maximum wavelength at 11° is calculated using the equation λmax = d * sin(θ), where λmax is the maximum wavelength, d is the spacing between the grating grooves, and θ is the angle of diffraction. This equation is known as the grating equation.
Finding the maximum wavelength at 11° is important because it allows us to determine the resolving power of the diffraction grating. The higher the maximum wavelength, the better the resolving power, as it means the grating can separate light into a wider range of wavelengths.
The number of grooves on the diffraction grating has a direct relationship with the maximum wavelength at 11°. As the number of grooves increases, the maximum wavelength also increases, resulting in a higher resolving power for the grating.
Yes, there are other factors that can affect the maximum wavelength at 11°, such as the angle of incidence, the width of the slits, and the quality of the grating. However, these factors are usually kept constant in order to accurately calculate the maximum wavelength using the grating equation.
