light takes a straight path.
Fermat's principle->the path of light will take after reflecting from a surface or passing through more than one medium according to the principal, light follows the path that will take the least time
how does water affect light path
use a mirror to change the path of light.
what is the path of light
Incident light ray
Light and electricity follow the path of least resistance.
Yes. But the path of light across the water/air boundary is not.
Daily Light on the Daily Path was created in 1875.
The chief ray angle is important in determining how light travels through a medium because it represents the angle at which light enters the medium. This angle affects how the light is refracted or bent as it passes through the medium, ultimately determining the path that the light will take.
light travels in a straight path
The Light Path - 2010 was released on: USA: 1 March 2010
Light will almost always travel from one place to another along a path that takes the least amount of time. This does not imply that it will take the path involves the least distance all the time.
