赤丸の問題が分かりません。答えはm=2です。 私はΔl=3√3d/2(=定数)であることから714(m+1/2)=429(m+3/2)と立式したのですが、答えが求まりませんでした。

薄膜における光の干渉は, シャボン玉の色付きなどに見られる身近な現象であるとともに、 膜厚計測など工学的にも重要な現象である。 図1のように, 屈折率 n, 厚さdの透明なフィ ルムに対して,入射角 Q1で波長の単色平面波の光が入射する場合を考える.ただし 262 n> 1 とし,nは波長によらず一定とする. 経路 Ⅰ 経路ⅡI 日 2 B 図 1 C 検出器 BY フィルム 0JJS bar ASTRO AR TEKS TERRES OD TUALE (い)の [1] 下記の経路I, 経路ⅡI を進む光について考える. フィルム周囲の媒質は屈折率 1.00 の空気とする. 以下の問いに答えよ. 経路 Ⅰ : 点Aで屈折し, 点 B で反射し、点Cで屈折して点Dに達する経路 経路ⅡI: 点A'を通り, 点Cで反射し、 点Dに達する経路 (1)経路Iの点Aで屈折した光は,屈折角 62 の方向に進んだ. sing を n, Q を用い て表せ. (2) 経路Iの各点 A, B, C および経路ⅡIの点Cを光が通過する前後における波長および 位相の変化について,最も適切な選択肢を以下の①~⑥の中から選べ.同じ選択肢を複 数回選択してもよい。 波長は長くなり, 位相は変わらない. (2) 波長は長くなり,位相は 180° ずれる . (3) 波長は変わらず、 位相も変わらない. (4) 波長は変わらず, 位相は 180° ずれる .
