Can you see light if not why?
Can you see light if not why? Radiation within a certain, tiny spectrum of around 400 to 800 nanometers in wavelength, causes objects to be seen by we humans. We can’t see the reflected light from those objects but we can see the objects. If the light shines through something translucent it appears to glow. […]
