[理工] [近物]-99台聯大-電機類
選擇題答案剛剛出來了 對幾個選項有點疑問 想請教一下板友
多選13的(D) (選錯的)
(D) Planck's law correctly explains the quantum of energy for the black body
我的疑問:Planck`s law應該是在假設"quantum of energy"的前提之下去解釋black
body radiation吧? Planck應該沒有對"quantum of energy"這件事提出解釋。
所以這選項是wrong(要選)，不知這樣有沒有問題..
多選16
The spectral lines for hydrogen
(A)have four for the visible light (B)have five for the visible light
(C)have four for the ultraviolet light (D) have visible,UV and IR light
(E)have no IR light
ans:AD
我的疑問:(A)(B)(C)這三個選項的幾條要怎麼看? 不是無限多條嗎
如果問題很蠢請多多包涵 @_@
