# Monochromatic laser light with a wavelength of \(\lambda = 500 \text{ nm}\) is incident perpendicularly on a diffraction grating containing \(500 \text{ lines per millimeter}\). What is the value of \(\sin\theta\) for the first-order (\(m = 1\)) intensity maximum?

Monochromatic laser light with a wavelength of \(\lambda = 500 \text{ nm}\) is incident perpendicularly on a diffraction grating containing \(500 \text{ lines per millimeter}\). What is the value of \(\sin\theta\) for the first-order (\(m = 1\)) intensity maximum?

- **A.** \(0.25\)
- **B.** \(0.40\)
- **C.** \(0.50\)
