How does the light from a laser reflect off objects with same color?
2013年8月25日 · How does a laser reflect off objects with the same color? When a laser beam hits an object, it is either absorbed, transmitted, or reflected. If the object is the same color as the laser beam, it will reflect the light back in the same color because the object's molecules are absorbing and emitting photons of that specific color.
Why do lasers have a "grainy texture" on the light that they ... - Reddit
It sounds like you are describing laser speckle, which is a result of what the laser reflects off of and not the laser source itself. Essentially, the laser beam interferes with itself upon reflection. The rough surface of the ceiling cause some parts to constructively interfere while others destructively interfere.
