As far as light is concerned it travels in a straight line from point A to point B. However, for a distant observer the trajectory may be a bit curved. The reason is that the geometry of space is a bit warped near a massive gravitational source like a black hole or even the sun.
It does not move in straight lines or constant velocity in accelerating reference frames or in non homogeneous media. The fact that the speed of light is independent of the observer's velocity is a relativistic effect. Formally it is a postulate of special relativity.

Light can travel through both in a medium and in a vacuum. But in a vacuum, there will not be any particles light can not reflect by hitting it. Hence, in a vacuum, light is invisible. In air, light can be reflected by hitting dust or some other particles, hence light is visible in the air. Light can be considered as waves. Light waves travel in di...
Since the diffraction effect of light is too small, normally light travels along a straight line. By using a simple experimental setup, we can prove that light travels along a straight line. Place three cardboard sheets back to back in front of a candle on the tabletop. Make sure that the cardboard sheets and the candles are placed in a straight li...
Light Travels in Straight Line Examples are as Follows:
1. Light comes out from a torch or train or lamp follows a straight line path. 2. A straight line path of light is visible when Sunlight comes out through the small holes in a dusty atmosphere. 3. When we place any opaque object in front of the object, we observe that the object will be invisible. It is because light cannot bend through the corners of the opaque object.

Solution. Light does not travel in a straight path. It travels as a wave. However as the wavelength is very small, it looks like it travels in a straight line. Also when light travels from one medium to another, it bends. It is called refraction.
What's the real cause that makes light photons to go in a straight line? and what are the factors that could change the path of light externally? (I'm excluding reflection, refraction and deviation here.)
Feb 15, 2018 · When you have a light source like a candle, light travels in many straight lines in all directions. Each light particle* travels in a straight line in a different direction. But there are so many of them that you can not perceive individual particles, so it seems like the light spreads uniformly.
Experiments show that when light interacts with an object several times larger than its wavelength, it travels in straight lines and acts like a ray. Its wave characteristics are not pronounced in such situations.
