Actually this topic is from solid state physics. I have derived Bragg's law first. it is very easy because it's just the condition for maxima. rest is calculation. Best regards.

wavelengths are same because same experiment is repeated with different crystals.

they have written in the question about first peak. it means the maxima corresponding to first order, hence n=1 is used.

dear,this is the easiest topic of solid state physics... look the wavelength is same for both experiments and they ask for first peak so n=1 for both experiments, therefore the two equations become equal and u can easily find theta for second experiment...best regards...

actually d is interplanar spacing. but here the types of material is not given so we take lattice parameter as d....

in this question we are finding the structure of crystal by some incident radiation. And take the same source for both. so lembda means wave length would be same
