半径为R,OC为截面内半径并且垂直于左侧边缘。现有a、b两束单色光分别从A、B两点沿平行于OC的方向从左侧射向透明材料,a光的出射光线与OC的延长线的交点记为M点,b光恰好不能从透明材料右侧射出。已知OA=OB=0.5R,OM=3R,下列说法正确的是aACMbbBD.若分别用单色光a、b在同一个双缝干涉实验装置上做实验,则a于b光的干涉条纹间距A.该透明材料对单色光a、b的折射率分别为3和2在该透明材料内的传播速度比b光在该透明材料内的传播速度小C.若将a光更换为频率更低的单色光,则M点的位置会向左移动光的干涉条纹间

6.如图甲为某小型电站的电能输送示意图,发电机通过升压变压器T1和降压变压器T2向用户供电,已知输电线的总电阻R=10Ω,,降压变压器T2的原、副线圈匝数之比为4:1,,副线圈与用电器R0组成闭合电路.若T1、T2均为理想变压器,T2的副线圈两端电压的变化规律如图乙所示,当用电器电阻R0=11时A.降压变压器副线圈两端交变电压B.降压变压器原线圈电流的有效值为10AC.升压变压器的输入功率为4650WD.发电机中的电流变化频率为60Hzu=220sin50πtV

(2)某同学实验中最终得到的油酸分子的直径和大多数同学的比较,数据都偏大。对于出现这种结果的原因,可能是由于。A.在求每滴溶液体积时,1mL溶液的滴数多记了2滴B.计算油酸面积时,错将所有不完整的方格作为完整的方格处理C.水面上痱子粉撒的较多,油膜没有充分展开D.做实验之前油酸溶液搁置时间过长
