Question

Hello, I need help with these two questions, since when I did them both of them are wrong for some reason? It is confusing in asked a tutor but they also got it wrong as well.

1:22 < What is the value of 0 for the first diffraction line (n = 1) in bcc iron (atomic radius 126 pm) when the X-ray wavelength is 58.0 pm? Hint: Consider the closest set of lattice planes. Incorrect, 47 attempts remaining Question 10 of 10 49 Retry Your submitted answer contains too many significant figures. Your submission: 13.31 ° Tap here or pull up for additional resources Feedback: You need to determine the correct distance between planes.
