focal length of coloured goggles

Dear Student ,
The coloured goggles have zero focal length .

Two factors on which focal length depends: The index of refraction of the lens material, and. the radius of curvature of the lens. Color does not matter.
  • -3
But thats not my question..is the focal length 0 or infinity ?

Zero otherwise it will be a magnifying glass
