\textbf{【实验报告注意事项】}
\begin{enumerate}
\item 实验报告由三部分组成:
\begin{enumerate}
\item 预习报告:(提前一周)认真研读\underline{\textbf{实验讲义}},弄清实验原理;实验所需的仪器设备、用具及其使用(强烈建议到实验室预习),完成课前预习思考题;了解实验需要测量的物理量,并根据要求提前准备实验记录表格(第一循环实验已由教师提供模板,可以打印)。预习成绩低于10分(共20分)者不能做实验。
\item 实验记录:认真、客观记录实验条件、实验过程中的现象以及数据。实验记录请用珠笔或者钢笔书写并签名(\textcolor{red}{\textbf{用铅笔记录的被认为无效}})。\textcolor{red}{\textbf{保持原始记录,包括写错删除部分,如因误记需要修改记录,必须按规范修改。}}(不得输入电脑打印,但可扫描手记后打印扫描件);离开前请实验教师检查记录并签名。
\item 分析讨论:处理实验原始数据(学习仪器使用类型的实验除外),对数据的可靠性和合理性进行分析;按规范呈现数据和结果(图、表),包括数据、图表按顺序编号及其引用;分析物理现象(含回答实验思考题,写出问题思考过程,必要时按规范引用数据);最后得出结论。
\end{enumerate}
\textbf{实验报告就是将预习报告、实验记录、和数据处理与分析合起来,加上本页封面。}
\item 每次完成实验后的一周内交\textbf{实验报告}(特殊情况不能超过两周)。
\item 除实验记录外,实验报告其他部分建议双面打印。

光电效应(英语:Photoelectric Effect)是指光束照射物体时会使其发射出电子的物理效应。发射出来的电子称为“光电子”。
光束里的光子所拥有的能量与光的频率成正比。假若金属里的电子吸收了一个光子的能量,而这能量大于或等于某个与金属相关的能量阈值(称为这种金属的逸出功),
则此电子因为拥有了足够的能量,会从金属中逃逸出来,成为光电子;若能量不足,则电子会释出能量,能量重新成为光子离开,电子能量恢复到吸收之前,
无法逃逸离开金属。增加光束的辐照度(光束的强度)会增加光束里光子的密度,在同一段时间内激发更多的电子,但不会
使得每一个受激发的电子因吸收更多的光子而获得更多的能量。换言之,光电子的能量与辐照度无关,只与光子的能量、频率有关。
被光束照射到的电子会吸收光子的能量,但是其中机制遵照的是一种非全有即全无的准则,光子所有能量都必须被吸收,用来克服逸出功,
否则这能量会被释出。假若电子所吸收的能量能够克服逸出功,并且还有剩馀能量,则这剩余能量会成为电子在被发射后的动能。
逸出功$W_0$是从金属表面发射出一个光电子所需要的最小能量。如果转换到频率的角度来看,光子的频率必须大于金属特征的极限频率,
才能给予电子足够的能量克服逸出功。逸出功与极限频率$\nu_0$之间的关系为
\begin{equation}
W_0 = h\nu_0
\end{equation}
其中,$h$是普朗克常数,$h\nu_0$是光频率为$\nu_0$的光子的能量。
克服逸出功之后,光电子的最大动能$E_{\max}$为
\begin{equation}
E_{\max} = h\nu - W_0 = h(\nu-\nu_0)
\end{equation}
其中,$h\nu$是光频率为$\nu$的光子所带有并且被电子吸收的能量。
实际物理要求动能必须是正值,因此,光频率必须大于或等于极限频率,光电效应才能发生。

\subsection{实验安全注意事项}
\begin{enumerate}
\item 实验过程中,禁止汞灯光线直接照射光电管,也不宜长时间连续照射加有光阑和滤光片的光电管。\textcolor{red}{\textbf{仪器暂不使用时,均须将汞灯和光电管盒用遮光盖盖上。}}
\item \textcolor{red}{\textbf{ 实验过程中,禁止用眼睛直视汞灯的出射光。}}
\item 实验完成后,需将光电管盒的遮光盖盖上,以保护光电管。
\item 汞灯和电源在测量前需要预热20分钟。汞灯光源功率为50W,温度较高\textcolor{red}{\textbf{须防止烫伤。}}
\item 切换滤光片时直接旋转滤光器,切换光阑时需要略微向外拔出一点,旋转到需要的光阑
尺寸后光阑会自动复位。
\item 注意:切换微电流放大器档位后,需要调零,否则会影响实验精度。
