Respuesta :
part 1: c) λ=0.34nm. part 2: a) d=0.118 nm part 3: c) The wavelengths of visible light are too long compared to the atomic spacing.
part 1: Calculating maximum wavelength:
The maximum wavelength of X-ray at the same location is λ2
λ2 = m * λ
where m is the fringe order of interference
here, m = 2 * 0.17
= 0.34 nm
hence, the X-ray wavelength to give a maximum at the same location is 0.34nm.
part 2: Calculating crystal plane separation:
d is the crystal plane separation.
θ = 0.8 rad
Now, converting radians into degrees.
θ = 0.8 * 180 / Π
= [tex]45.83^{0}[/tex]
Now, calculating d
2 * d * sinθ = m * λ
d = m * λ / 2 * sinθ
= 1 * 0.17 / 2 * sin([tex]45.83^{0}[/tex])
= 0.118 nm
part 3:
The wavelength of visible light is 380 to 700 nm which is large to study the structure of proteins.
