blue violet light

Specifically, what is going on here is the Earth's atmosphere scatters light in the blue and violet wavelength range, so the remaining wavelengths of light appear yellow.

更准确一些的说，地球大气层把蓝色和紫色的波长范围进行散射，所以光线中剩下的波长就显现出了黄色。

Water refracts, or bends, the light, separating it into red, orange, yellow, green, blue, and violet

水把光线折射或弯曲，而分离为红、橙、黄、绿、蓝和紫色。

The lasers most people are familiar with are the green dots highlighting a PowerPoint presentation or the blue (actually closer to violet) light found in Blu-ray technology.

大多数人所熟悉的激光器是在做PowerPoint演示文稿时所使用的有着高亮度绿色圆点或着蓝色(其实更接近紫色)的紫激光技术。
