Material dispersion is caused by the velocity of light (or its refractive index) being a function of wavelength.
Could you explain about the function of “being” in the sentence above? I think it is present participle but I am not sure and confident to using it in a sentence.
Being means the same thing here as “which is”. I’m not a fan of this sentence structure, as it is both confused and confusing. Refractive index is not a property of the light which passes through the material, but of the material itself.
Thanks a lot, Steve!
Do you think that if a sentence use many phrases such as: which is, which was, who is,…it won’t be interesting and, maybe, horrible?
I am not a technician but I have learnt that refractive index also depends on wavelength of the light which passes through the material.
If you have a three-ring circus of a sentence, the reader doesn’t know what you want him to focus on. The ringmaster knows to shut down the other rings when the pretty girl walks the tight wire. Short, punchy sentences are more effective at communicating a single idea.
As Jay Leno snack food ads, eat all you want; we’ll make more. Periods and capital letters aren’t being rationed; w’re allowed to use multiple sentences.
