Double Slit Interference

双缝干涉

Displacement y = (Order m x Wavelength x Distance D)/(slit separation d)

位移 y = (序数 m × 波长 × 距离 D ) / ( 条纹间距 d )

For double slit separation d = micrometers = x10^ m

双缝间距 d = 微米 = x10^ m
中文译文中的待填/计算数值依次对应:1:a 2:ab 3:ap。实际数值以上方原输入框为准。

and light wavelength λ = nm at order m =,
且光波长 λ = nm 在 m = 的顺序中,
中文译文中的待填/计算数值依次对应:1:w 2:m。实际数值以上方原输入框为准。

This calculation is designed to allow you to enter data and then click on the quantity you wish to calculate in the active formula above. The data will not be forced to be consistent until you click on a quantity to calculate. Default values will be entered for unspecified parameters, but all values may be changed.

此计算旨在允许你输入数据,然后点击上方交互式公式中你希望计算的量。数据不会被强制保持一致,直到你点击一个量进行计算。未指定的参数将输入默认值,但所有值都可能被更改。

Note: The small angle approximation was not used in the calculations above, but it is usually sufficiently accurate for laboratory calculations.

注意:上述计算中未使用小角近似,但通常在实验室计算中足够准确。
