    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.

    I hope you got it my point dear
  • Ruby negi thankyou
    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...

    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
