On a small time scale, glass is in a solid state. When you look at a window, it appears solid.
However, it has been observed that over a very long period, glass starts to act like a liquid.
It can thus be characterized by two different states depending on the time scale considered.<span />
<span>E = ħc / λ
ħ = plancks constant = 6.626x10^-34 Js
c = speed of light = 2.999x10^8 m/s
λ = wavelength of light = 670.8x10^-9 m
E = (6.626x10^-34 Js) x (2.999x10^8 m/s) x (1 / 670.8x10^-9 m)
E = 2.962x10^-19 J
</span><span>3x10^8 / (670.8 * 10^-9)
=4.47x10^14 Hz
4.47x10^14 Hz multiplied by plank's constant = 2.9634x10^-19
