Web8 de abr. de 2024 · Actual path length or Geometric length is simply the real length travelled by the light in the medium. Note: For clarity, we can prove the formula for the optical path length as follows: The distance travelled by light in the medium is. d g = v m × t. but now, the distance the length would have travelled in vacuum in the same time would be.
