B選項為什麼是對的

電 某生用電子作雙狹縫干涉實驗,在狹縫後的螢幕上有電子偵測器,每次電子在垂直入 射雙狹縫後,會撞擊偵測器顯示出一亮點。用許多電子逐一重覆上述步驟後,統計 幕上各處偵測器所顯示的亮點數目,可以得到類似光波的干涉條紋。在螢幕上有甲、 乙、丙三點,甲點與乙點分別位於兩個狹縫的正後方,丙點為甲、乙之中點。下列敘 述,哪些正確?(應選2項) (A)使用不同速率的電子重覆實驗,丙點一定是亮點(B)使用速率較大的電子重覆實 驗,所形成的干涉條紋較密(C)使用不同速率的電子重覆實驗,甲、乙兩點一定是亮 點(D)將電子換成中子,且將電子偵測器換成中子偵測器,丙點不會是亮點(E)電子 射出的時間間隔增長為原來的兩倍,重覆實驗,則干涉條紋的間隔將增為兩倍。 BAB

This savory, buttery, salty (11) is consumed at theaters in almost every country in the world. (12) In fact, most early theaters did not want the noisy, smelly food to be eaten on their premises.

Theaters therefore agreed to allow independent street vendors to operate (13) outside their doors or in their lobbies.
