SUMMARY
The discussion focuses on calculating diffraction angles and slit width using the formula dsin(θ) = mλ. Given a monochromatic light wavelength of 441 nm and a distance of 2.16 m from the slit to the screen, the distance between the second minimum and the central maximum is 1.62 cm. The angle of diffraction θ for the second minimum is derived using the approximation sin(θ) ≈ 1.62 cm / 2.16 m, leading to the solution of the problem as confirmed by participants.
