Question

Optical path is equal to

Answer 1

Answer:

In optics, optical path length (OPL) or optical distance is the product of the geometric length of the path followed by light through a given system, and the index of refraction of the medium through which it propagates.

Answer 2

Answer: The GPD times the medium's refractive index yields the optical path length in a homogeneous medium.

Explanation:

The path a light beam takes as it moves through an optical medium is known as the optical path (OP). The length of a segment in a particular OP, or the Euclidean distance integrated along a ray between any two places, is known as the geometrical optical-path length (GPD), also known as the geometrical path length. By utilizing folded optics, an optical device's mechanical length can be lowered to less than the GPD. The GPD times the medium's refractive index yields the optical path length in a homogeneous medium.

Factors affecting optical path:

Path of light in medium, or between two media is affected by the following:

1. Reflection
2. Total internal reflection
3. Refraction
4. Dispersion of light
5. Absorption
