[學科] 一題考古題
這是一題考古題
為了怕翻譯錯誤而曲解原意,直接打英文上來
for a particle in box of nanometer size, the energy level is quantized
ΔE=E -E =((2n+1)h^(2))/(8mL^(2))
(n+1) (n)
use this information to quantitatively explain the following observations
(a)larger sized quantum dots emitted lights with longer wavelength
這題我想"larger sized quantum dots"會有比較大的L所以ΔE比較小放出來的
光波長就大,這樣想正確嗎?
(b)heavy particles have larger entropy than lighter particles
of the same size of box at the same temperature
這題我就沒甚麼頭緒,想請問大家
謝謝!!
