题目：光的衍射动画
动画步骤：
1. 显示一个光源，发出平行光。
2. 将光源移至一个障碍物前，形成衍射环。
3. 放大障碍物，观察衍射环的变化。
4. 缩小障碍物，观察衍射环的变化。
5. 改变光源的角度，观察衍射环的变化。
6. 显示不同波长的光，观察其衍射效果。
动画解释：
1. 光的衍射是光绕过障碍物或穿过小孔时发生的现象，当光波波长与障碍物或小孔尺寸可比时，光波会绕过障碍物或穿过小孔，形成明暗相间的衍射环。
2. 障碍物的大小和形状会影响衍射环的形状和亮度。当障碍物尺寸减小或形状改变时，衍射环的形状和亮度也会发生变化。
3. 不同波长的光具有不同的衍射效果，波长越长，衍射效果越明显。
英文翻译：
The animation of light diffraction:
Steps:
1. Display a light source emitting parallel light.
2. Move the light source in front of an obstacle, forming diffraction rings.
3. Enlarge the obstacle and observe the changes in the diffraction rings.
4. Reduce the obstacle and observe the changes in the diffraction rings.
5. Change the angle of the light source and observe the changes in the diffraction rings.
6. Display light of different wavelengths and observe their diffraction effect.
Explanation:
1. Light diffraction is a phenomenon that occurs when light passes around obstacles or through small holes. When the wavelength of light waves is compared to the size of the obstacles or small holes, the light waves will bypass the obstacles or pass through the holes, forming bright and dark rings.
2. The size and shape of the obstacles have an impact on the diffraction rings' shape and brightness. When the size or shape of the obstacles changes, the shape and brightness of the diffraction rings also change.
3. Different wavelengths of light have different diffraction effects, with longer wavelengths having stronger diffraction effects.
