1.扬氏双烧干涉实验是科学史上一个著名实验,该实验有力地证明了光是一种波,光电效应观象则证明了光具有粒子性,如图所示为单色激光束的双缝干涉实验,下列说法正确的是()A.若将光屏向右移动,条纹间距变小B.图样上出现区是因为此处没有光达C.若速住S1,,光屏上仍能出现明暗相阿的条纹,但是其条纹问距发生变化,中间较宽,两边依次变率D.光的干涉和光的衍射的图样不同是因为它们的本质不同,光的干沙的本质是光的叠加,而光的衍射不是

2.如图1所示,一标准玻璃板甲放在玻璃板乙的上表面,两板间右端夹上几张纸,形成空气薄膜。用波长为λ的光垂直照射玻璃板甲的上表面,从上向下观察时看到明暗相间的干涉条纹如图2所示。若在玻璃板甲上表面涂上增透膜,增透膜的折射率为,再用该光垂直照射玻璃板甲的上表面,则图2A.增透膜的最小厚度,d=2B.增透的最小厚度d=4nC.原来的明纹变为暗纹D.条纹间距将变大

③你通过采集数据,描绘出了该二极管加正向电压时的伏安特性曲线,和厂家提供的完全相同。你又将该二极管与阻值为50Ω的定值电阻串联后接到电动势为3V、、内阻不计的电源两端,如图d所示,此时该发光二极管的电功率为W(结果保留两位有效数字)。
