Which best describes Zach's error? Zach listed the process of how laser beams are
produced with crystals.
1. A flashlamp pumps energy through the crystal.
2. Atoms in the crystal absorb and then release some of the
energy as light
3. Light bounces off mirrors and occasionally bounces off
crystal atoms, increasing in energy.
4. Some light escapes the tube through the highly reflective
mirror, forming a concentrated beam.
The crystal pumps energy through the flashlamp:
the flashlamp does not pump energy through the
crystal
O The atoms in the crystal do not release energy, they
only absorb energy
Light does not bounce off mirrors; it focuses through
glass lenses.
Light escapes through the partially reflective mirror,
not the highly reflective mirror.
