13.在探究凸透镜成像特点实验时,当凸透镜、蜡烛、光屏处在如图所示的位置时,恰好在光屏上成清晰的像,下列说法中正确的是()A.光屏上成的是倒立、放大的像B.此现象的原理是望远镜物镜的成像原理C.仅移动凸透镜仍可得到清晰的像D.该凸透镜的焦距可能是10cm
1.在真空管中充入氢气,接上直流高压电源,在电场的激发下,氢原子会发光,巴尔末坚信其中几条发光谱线的波长应服从某种规律,于是他在1885年提出了巴耳末系谱线波长λ的公式,若用频率来表示则为v=Rc(12v-1n^2)(n=3,4,5,3,4,5,…),其中R叫里德伯常量,c表示真空中的光速,下列说法正确的是A.里德伯常量R是没有单位的负值B.若用波长倒数来表示巴尔末公式,则巴尔末公式为1=R^-1(12^2-1n^2)(n=3,4,5,)C.氢原子从n=2向n=1跃迁时放出的光子频率为3Rc4D.氢原子从n=3向n=2跃迁时放出的光子频率为
8.如图所示的电路中,电源的电动势为E、内阻为r,R2、R3、R4为定值电阻,闭合开关S,当滑动变阻器R1的滑片向上滑动时,下列说法正确的是BA.电阻R3的功率增大B.电阻R2的功率增大C.通过R4的电流增大D.通过R1的电流增大
