And you can use a trusty ray diagram to show how this image forms.

您可以使用可靠的射线图来 显示此图像的形成方式。

And when we construct a ray diagram for a diverging lens, there are a few key differences.

当我们为 镜头垫片，有几个关键的区别。

This is the thin lens equation, which is derived from ray diagram geometry.

这是薄透镜透镜方程，它是导数 从射线照相的几何形状。

Finally, we built ray diagrams to discover how objects are viewed through different kinds of lenses at different points.

最后，我们构建了 X 射线图，以发现物体在不同点通过不同类型的透镜的外观。

Let’s show this using a ray diagram, which tells us about the position and size of images as seen through a lens.

让我们使用射线图来展示这一点，它告诉我们通过镜头看到的图像的位置和大小。

Let's show this using a ray diagram, which tells us about the position and size of images as seen through a lens.

让我们使用射线照片来证明这一点，它向我们展示了通过镜头看到的图像的位置和大小。

And in a ray diagram, you can see that the tangent of the first angle, theta, is the height of the real image over the focal length of the objective lens.

在射线图中，您可以看到 第一个角度的切线 theta 是真实图像 在物镜焦距上的高度。
