四、簡答題(每小題 4 分,共 12 分) 已知強度為 I 的光束,穿透厚度1公分的玻璃後,光束強度會降低為1×80%,即穿過 厚度n公分的玻璃後,其中n為整數,光束強度減為I,其關係式為 I=1×(0.8)"。請判 斷下列各小題中的敘述是否正確,並說明理由。 題目 (1)光束穿透厚度6公分的玻 璃後的強度,是穿透厚度 4公分的玻璃後的強度的 1.5 倍。 (2)光束穿透厚度3公分的玻 璃後,強度為0.512。 (3)要讓光束穿透玻璃後,其 強度小於原來的一半,則 須使用的玻璃厚度最少要 4公分。 I = 1 * (0.8)6 20 I = lox (0.8) L (8) 4 解析 相除 I = I₂ (0.8) 11 E(S) 0.8 T Jox 0.50 0.64 (倍) A:錯 正確 (08) BER 8 (58) Stext-st MJI
