A. It travels in a curved line B. Light travels in a straight line C. It travels randomly D. Light travels in circles 相关知识点: 试题来源: 解析 B。解析:光沿直线传播是基本的科学知识。A选项“沿曲线传播”错误。C选项“随机传播”不符合光的传播特性。D选项“沿圆形传播”也是错误的。反馈...
C. By total internal reflection. D. By scattering. 相关知识点: 试题来源: 解析 C。解析:文中提到 Optical fibers use light waves to transmit information. Light is sent through a thin glass or plastic fiber by total internal reflection.所以光在光纤中是通过全内反射传播的。反馈 收藏 ...
