A)26.02°
B)1.94°
C)5.05°
D)0.44°

The angle for the m-th order minimum in a single slit diffraction pattern is given by the formula: a * sin(θ) = m * λ, where a is the slit width, θ is the angle, m is the order, and λ is the wavelength. Given m = 5 at 7.00°, we can find a. Then, using m = 18, we solve for θ. The calculation shows that θ ≈ 26.02°.
