Answer:
d = 1.82 10⁻⁶ m = 1.82 μm
Explanation:
The diffraction phenomenon is explained by a similar equation Young's double slit equation
d sin θ = n λ
Where d is the spacing between the bars, θ is the angled diffraction, n in an integer representing the order of diffraction and λ is the wavelength of light
Let's calculate
d = n λ / sin θ
d = 1 470 10⁻⁹ /sin 15
d = 1.82 10⁻⁶ m = 1.82 μm
A wheel and axle and an inclined plane.
(31-15 = 16).
Explanation:
the element phosphorus (P) has an atomic number of 15 and a mass number of 31. Therefore, an atom of phosphorus has 15 protons, 15 electrons, and 16 neutrons
