Module Contents

physics.bragg_angle.bragg_angle(distance: float, order: int, wavelength: float) → float

Calculate the Bragg diffraction angle using the formula: sin(θ) = (n * λ) / (2 * d)

Parameters: distance d (float): Distance between crystal planes (in meters). order n (int): Order of reflection. wavelength λ (float): Wavelength of the radiation (in meters).

Examples: >>> bragg_angle(2.2e-10, 1, 2.2e-10) 30.0

>>> bragg_angle(5e-10, 2, 1e-10)
11.5

>>> bragg_angle(4e-10, 1, 4e-10)
30.0
