Calculation of Diffraction Grating Period

To find the period of a diffraction grating, we can use the formula:

d = (λ / sinθ) / m

where: - d is the period of the diffraction grating, - λ is the wavelength of light, - θ is the angle of diffraction, and - m is the order of the spectrum.

Given: - Wavelength (λ) = 0.56 μm (micrometers) - Angle of diffraction (θ) = 10 degrees - Order of the spectrum (m) = 2

Substituting the given values into the formula, we can calculate the period (d) of the diffraction grating.

d = (0.56 μm / sin(10 degrees)) / 2

Using a calculator, we can evaluate this expression to find the period of the diffraction grating.

d ≈ 2.02 μm

Therefore, the period of the diffraction grating is approximately 2.02 μm.
