Question

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. which best describes zachs error? the crystal pumps energy through the flashlamp; the flashlamp does not pump energy through the crystal. 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.

Explanation:

In laser - production with crystals, light escapes through a partially - reflective mirror, not a highly - reflective one. A highly - reflective mirror would mostly reflect the light back into the laser cavity, while a partially - reflective mirror allows some light to escape as the laser beam.

Answer:

Light escapes through the partially reflective mirror, not the highly reflective mirror.
