Incident light ray
Light travels in a straight path because it follows the principle of rectilinear propagation, which states that light travels in a straight line unless it interacts with a different medium or object that causes it to bend or scatter. This behavior is governed by the laws of physics, specifically the law of reflection and refraction.
To support that light travels in a straight path, take a flashlight and turn it on. Then, you could point it in any way around a room, upside down, angled, tilted, etc., and where ever you shine the flashlight, the ball of light is always straight across from the flashlight.
The branch of physics that deals with light and its interaction with matter is called optics. Optics studies how light behaves, the properties of light, and how light interacts with various materials. It encompasses topics such as reflection, refraction, diffraction, and polarization.
In physics, a ray is a straight line that represents the path along which light or other forms of radiation travel. Rays are commonly used to study the behavior of light as it reflects, refracts, or undergoes interference. They help simplify the analysis of complex optical systems.
Quantum physics determined that light acts like an electromagnetic wave and a particle at the same time.
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.
light takes a straight path.
how does water affect light path
use a mirror to change the path of light.
what is the path of light
Incident light ray
?????????????????
The main relevant physics in this case is reflection of light.
Light and electricity follow the path of least resistance.
