1. 物理试卷分为第I卷(选择题)和第II卷(非选择题)两部分,第I卷1至2页,第II卷3至4页,共110分。

2. 答卷前,考生务必将自己的姓名、考籍号填写在答题卡上;并在规定位置粘贴考试用条形码。

答卷时,考生务必将答案涂写在答题卡上,答在试卷上的无效。

考试结束后,只将答题卡交回。

第I卷注意事项:1. 每题选出答案后,用2B铅笔将答题卡上对应题目的答案标号涂黑。

如需改动,用橡皮擦干净后,再选涂其他答案标号。

2. 本卷共7题,每题6分,共42分。

每小题给出的四个选项中,有的只有一个选项正确,有的有多个选项正确,全部选对的得6分,选对但不全的得3分,有选错的得0分。

1. 下列说法正确的是A. 在麦克斯韦预言的基础上,赫兹通过实验证实了电磁波的存在B. 所有波都能发生偏振现象C. 相对论质能关系式为E=MCD. 1 µF=1X10-3 F2. 如图所示,甲为某一简谐波在t=1.0s 时刻波的图像,乙为甲图中b点的振动图像。

则下列说法正确的是A. 该简谐波的波速v=6m/sB. ¢t=1.0 s时刻,a点的运动方向向下C. 若该波能与另一列简谐波发生稳定的干涉,则另一列波的频率为1 H ZD. 要使该波能够发生明显的衍射,则障碍物的尺寸应远大于4M3. 如图所示,理想变压器原、副线圈的匝数比为10 :1,b是原线圈的中心接头,电压表V和电流表A均为理想电表,除滑动变阻器电阻R以外的其余电阻不计,从某时刻开始在正确的是C. 单刀双掷开关与A 连接,在滑动变阻器触片P 向上移动的过程中,电压表和电流 表的示数均变小D.当单刀双掷开关由a 扳向b 时,电压表和电流表的示数均变大4 甲为某同学利用半圆形玻璃砖测定玻璃折射率n 的装置示意图。

他让光从空气射向 玻璃砖,在正确操作后,他利用测出的数据作出了图乙所示的折射角正弦(sinr)与入射角正弦(sini)的关系图像。
