( CO ₂ ) laser uses

Options

  1. Amicrowaves
  2. Binfra red
  3. Cultra violet
  4. Dvisible light

Correct answer

C. ultra violet

Step-by-step solution

One has to use higher energy to produce radiation in the visible region. In ( CO ₂ ) laser two electrodes produce discharge which is used. Therefore ultraviolet rays are used to produce light in any lower energy region.
