Guessing (A) because it had the highest velocity number on the graph and it matched 1s
When they are in electron shells far from the nucleus.
Answer:
<h2>In physics and chemistry, ionization energy or ionisation energy is the minimum amount of energy required to remove the most loosely bound electron of an isolated neutral gaseous atom or molecule. It is quantitatively expressed as </h2><h2>X(g) + energy ⟶ X+(g) + e−</h2>

Answer:
Wavelength is calculated as 213.9 nm
Solution:
As per the question:
Wavelength of light = 570 nm
Time, t = 16.5 ns
Thickness of glass slab, d = 0.865 ns
Time taken to travel from laser to the photocell, t' = 21.3
Speed of light in vacuum, c =
Now,
To calculate the wavelength of light inside the glass:
After the insertion of the glass slab into the beam, the extra time taken by light to cover a thickness t = 0.865 m is:
t' - t = 21.3 - 16.5 = 4.8 ns
Thus
where
n = refractive index of the medium
v = speed of light in medium
n = 2.66
Now,
The wavelength in the glass:
