Answer:
the atomic radius of a lithium atom is 0.152 nm
Explanation:
Given data in question
structure = BCC
lattice constant (a) = 0.35092 nm
to find out
atomic radius of a lithium atom
solution
we know structure is BCC
for BCC radius formula is /4 × a
here we have known a value so we put a in radius formula
radius = /4 × a
radius = /4 × 0.35092
radius = 0.152 nm
so the atomic radius of a lithium atom is 0.152 nm
Answer: (a) 1.11 nm/mm
Explanation:
Monochromator is a device which is used to transmits a delectable band of wavelengths of light wavelengths available at the input.
Assuming focal length monochromator equipped with a 1200-groove/mm grating
The formula for the first-order reciprocal linear dispersion is
where F is the focal length and n belongs to order of the first spectra.
Make sure you have used the conversion factors correctly as it will have a major impact on the calculation of the answer.
