Answer:
The separation between the two lowest levels =
The values of n where the energy of molecule reaches 1/2 kT at 300K =
The separation at this level = 1.8 * J
Explanation:
Knowing the formula
En =
Mass of oxygen molecule
m (O2) = 32 amu *
So the energy diference between the two lowest levels:
E2 - E1 =
E2 - E1 =
Now we should find n where the energy of molecule reaches 1/2 kT
En = =
=
by the end is necessary to calculate the separation of the level
En - En-1 =
= 1.8 * J
Answer:
The angle between the extreme red and extreme violet light in the glass is 1.18°
Explanation:
According the Snell's law:
Where
na = refractive index of air = 1
θa = angle of incidence in air = 66°
For red light nb = 1.61
Replacing:
For violet light nb = 1.66
So, the angle between the extreme red and extreme violet light in the glass is 34.57-33.39 = 1.18°
