Which of the following equation describes Bragg’s law of diffraction? (Assume that all symbols have their usual meaning.)

Which of the following equation describes Bragg’s law of diffraction? (Assume that all symbols have their usual meaning.) Correct Answer 2d sinθ = nλ

Bragg’s law, which describes the constructive interference conditions for θ to be at its strongest: nλ = 2d sinθ, where λ is the wavelength of the incident wave and and n is the order of diffraction which is always a positive integer and d is the interplanar spacing and θ = angle of diffraction. This equation can be easily derived upon constructing a basic wave reflection diagram taking incident angle as θ.

Arjun covers a certain distance from his home to college at a usual speed of 24 km/hr and takes a certain time. When he increases usual speed by 6 km/hr, he takes 30 minutes less than usual. If he reduces his usual speed by 4 km/hr, he takes 30 minutes more than usual. Find the distance from his home to college.
