In a single-slit diffraction experiment,what is the largest slit width for which there are no minima when the wavelength of the incident light on the single slit is 600 nm?

The condition for the minimum intensity in single-slit diffraction is given by sinθ = λ/d, where θ is the angle between the direction of the diffracted light and the direction of the incident light, λ is the wavelength of the incident light, and d is the width of the slit. To have no minima, sinθ should be equal to zero, which occurs when θ = 0. Therefore, for θ = 0, we have sinθ = sin(0) = 0 = λ/d, which implies that d can take any value. Hence, there is no limit on the width of the slit. Therefore, the largest slit width for which there are no minima is infinite, and option B is the closest answer choice to that.
