A particular spectrum line corresponds to a certain definite light wavelength.

某特定的谱线就代表一个确定光的波长。

As discussed, the mercury-vapor UV lamps use a greater intensity light wavelength.

罗伯特说：“如前所述，汞蒸气UV照射器采用的是更大的光照强度。

I am sure you all know from physics class about how light moves in microscopic ways and that we can only see light when the wavelength of that light is in a specific range.

我相信，你们在物理课上都学过光是如何以微观的方式运动的，以及只有在光的波长在特定的范围内时我们才能看到光这一事实。

When the asbestos is seen in light near that wavelength, the minerals look darker than those around them.

And the relationship that he put forth is that the momentum is equal to Planck's constant times nu divided by the speed of light, or it's often more useful for us to think about it in terms of wavelength.

爱因斯坦提出的关系式是,动量等于普朗克常数,乘以υ除以光速，或者用波长来表示,通常更容易让我们想明白。

And what de Broglie said is well, if it's true that light, which has a wavelength can have momentum, then it must also be true that matter, which has momentum, also has a wavelength.

德布罗意说的是，如果光具有波长和动量是对的,那么物质具有动量和波长,也一定是对的。

In two of the trials, the box was dark for 12 minutes and then illuminated for 48 minutes with either long-wavelength red light or short-wavelength blue light directed at the subjects' corneas. (Light color is determined by its wavelength.) The box was dark in a control experiment.

In the case of light whose wavelength is an exact submultiple of this distance, crest falls on crest, and trough on trough, reinforcing the colour.

That bit of trickery works because the light can be manipulated when the material is shaped with features about as big as the light's wavelength - less than a millionth of a metre for light that we can see.
