Find the first-order diffraction angle for green light

Reference no: EM13523130

The wings of some beetles have closely spaced parallel lines of melanin, causing the wing to act as a reflection grating. Suppose sunlight shines straight onto a beetle wing.

If the melanin lines on the wing are spaced 2.0 apart, what is the first-order diffraction angle for green light (lamda=550 nm)?
