Both, there are two different types of molecules to distinguish that
Chemical change, we can't change the bread back the way it was before
Hope this helps!
Answer:
λ = 2.62 x 10⁻¹⁰ m = 0.262 nm
Explanation:
We can use Bragg's Law's equation to solve this problem. The Bragg's Law's equation is written as follows:
mλ = 2d Sin θ
where,
m = order of reflection = 1
λ = wavelength = ?
d = distance between the planes of crystal = 3.5 x 10⁻¹⁰ m
θ = strike angle of waves on plane = 22°
Therefore, substituting the respective values in the equation, we get:
(1)λ = (2)(3.5 x 10⁻¹⁰ m)(Sin 22°)
<u>λ = 2.62 x 10⁻¹⁰ m = 0.262 nm</u>
