    and what is the raman effect?

    A black light filter causes white light to become black light. I was taught that black light is faster then light.

    I would imagine you could create something to slow down white light to infrared light. I was taught that infrared is slower then light.

    you were taught wrong, please stay off the forum

    kthnxbye


    everything is mathematical.

    That is total nonsense. Light, in a vacuum precisely and in air to a very good approximation, travels at THE SPEED OF LIGHT. It doesn't matter what the color is, at least in a vacuum. There is a difference in materials, as we discussed but you denied, when talking about prisms and the dependence of the index of refraction on wavelength.

    I have no idea what you were taught. I almost certainly was not this. Apparently you did not learn much, despite what might have been taught.

    The last time they checked the speed of light, they were measuring the time it took light to have an effect on matter. Not the actual speed of light creating rays. Maybe that is what is misunderstood or holding back science.

    That could be why they think many different rays all go the same speed. Because they just measure the time it takes to effect an object.
