Answer: triple point.
At the melting point can exist two phases in equilbrium (liquid and solid).
At the boiling point can exist two phases in equilibrium (liquid and gas).
The critical point is the limit at wich gas and liquid can coexist.
And, indeed, at the triple point can solid, liquid and gas can coexist.
The wavelength is 4.0 * 10^-13 m while the frequency is 7.5 * 10^20 s−1
Using the formula;
E =hf
Where
E = Energy of the photon
f = Frequency of photon
h = Plank's constant = 6.6 * 10^-34 Js
To obtain the energy in Joules;
E = 3.02 × 10^11 J/mol/6.02 * 10^23 mol
= 5 * 10^-13 J
f = E/h
f = 5 * 10^-13 J/6.6 * 10^-34 Js
f = 7.5 * 10^20 s−1
f = c/λ
c = speed of light = 3 * 10^8 m/s
λ = c/f
λ = 3 * 10^8 m/s/7.5 * 10^20 s−1
λ = 4.0 * 10^-13 m
The wavelength is 4.0 * 10^-13 m while the frequency is 7.5 * 10^20 s−1
