Abstract

本实用新型提出了一种光传播实验尺,是在透明塑料直尺的一端设置电源发光装置,透明塑料直尺上设有一根纵向刻度线,光源直照透明塑料直尺上的刻度线,即可直观的观测到光的直线传播,该装置结构简单,学生易制作。

Description

光传播实验尺
技术领域
本实用新型涉及光传播实验尺。
背景技术
目前,中学物理光学传播实验教具,存在结构复杂,学生不易制作的不足。
发明内容
本实用新型的目的是提供一种结构简单,易制作的光传播实验尺。
其技术方案是:在透明塑料直尺一端设置电源发光装置,光源就可沿直尺传播到另一端。该发光尺插入水中,可直接测到光的折射。所述光传播实验尺,结构简单,学生易制作。
附图说明
图1为本实用新型的结构原理图。
具体实施方式
如图1所示的光传播实验尺,在透明塑料直尺1一端设置有由灯泡、电池、导线、开关组成的电源发光装置2,透明塑料直尺1上设有一根纵向刻度线3,灯泡对准直尺上的相应刻度线3,直尺的另一端即显现该刻度线,即可直观的观测到光的直线传播。

Claims (1)

1、一种光传播实验尺,其特征在于:在透明塑料直尺的一端设置有电源发光装置,透明塑料直尺上设有一根纵向刻度线,光源直照透明塑料直尺上的刻度线。
