Here’s another pop quiz. a) Given the speed of light and the small quarters inside a CD player compartment, what difference does it make if the light, regardless of wavelength is scattered or not ? The sensor detects the light at the same time whether scattered, reflected or direct.
b) Also black matter being black only means it absorbs the light we can see, just like other black things. That alone provides no evidence that either IR or UV wavelengths are absorbed. Even if it was proven to absorb IR, and other black things not, it would not seem to matter given point a).
BTW water absorbs IR frequencies. You might moisten some white matter, stick it in there, and put black matter to shame.
Not to mention that unless the compartment is totally sealed in material absorbing the laser frequencies, some nasty light might still get reflected!!!! Watch out!!
BTW, anyone know the actual EM frequency range that sensors used in CD players actually detect? That would be a good start to know what will be most effective in absorbing the light, not that it is likely to matter....
BTW rumor also has it windmills cause cancer. Go Figure!
