[理工] [物理] 光波干涉
題目
As the spacing of the slits in a two-slit interference experment
with a fixed wavelength increases, the angle at which the first-order
bright fringe occurs
(a) increases (b) decreases (c) remains the same
答案是(a) increases
可是根據題目的說法 dsinθ=mλ
d increases
m the same
λthe same
那sinθ要 decreases
所以angle應該要 decreases才對阿
為什麼答案是(a)??
