Tom Cruise cuts the glass with a laser.
Have you ever seen souvenir glass cubes with a three-dimensional image inside?
The glass is transparent and does not absorb the visible spectrum.
The laser is visible to the eye - the laser radiates in the visible spectrum, no more.
Transparency of glass is approximately 95%. 5% is absorbed. We consider the power of the laser necessary for cutting, depending on the batteries and the size of such a laser. The topic is closed.
