There are only a few nanostructures precise enough to exclusively scatter violet light.

只有极少的足够精细的纳米结构可以单独散射出蓝紫色的光。

Red light has a longer wavelength, about twice the distance between crests as violet light.

红光的波长较长，波峰之间的距离大约是紫光的两倍。

The rise in global temperature cuts rice-growing time, and ultra violet light radiation from the sun reduces tolerance to disease.

全球气温的升高减少了稻米的生长时间，来自太阳的紫外线辐射降低了抗病力。

Red light bends the least, and violet light bends the most.

红光弯曲最小，紫光弯曲最大。

Different colors of light carry different amounts of energy: red light is less energetic than green light, which is less energetic than blue or violet light.

不同颜色的光蕴含不同等级的能量，红光能量比绿光更少，绿光能量比蓝光与紫光的能量更少。

He brought the umbrella swishing down through the air to point at Dudley — there was a flash of violet light, a sound like a firecracker, a sharp squeal.

他甩伞嗖的一声在空中挥了一下，然后直指达力，忽的一道紫罗兰色的闪光、一声鞭炮似的响声、一声尖叫。

As Marilla lifted it out, the sunlight, falling through the vines that clustered thickly about the window, struck upon something caught in the shawl—something that glittered and sparkled in facets of violet light.

玛丽拉把它拿出来时，阳光透过密密麻麻地簇拥在窗户周围的藤蔓洒落下来，照在挂在披肩上的什么东西上——那东西在紫罗兰色的光芒中闪闪发光。
