Ibn al-Haytham (965 in Basra - c. 1040 in Cairo) a Muslim scientist, proved that rays of light travel in straight lines, and carried out various experiments with lenses, mirrors,refraction, and reflection. He was also the first to reduce reflected and refracted light rays into vertical and horizontal components, which was a fundamental development in geometric optics.Book of Optics.(Ibn al-Haytham)
I have the straight answer from the Internet and my science teacher that light travels in the motion of waves.
Light travels in straight lines due to the principle of rectilinear propagation. This is supported by the fact that light changes direction when it passes through different mediums, such as air to water, which causes refraction. Additionally, shadows cast by opaque objects also demonstrate how light travels in straight lines.
Light travels in a straight line, and it cast a shadow.
Straight lines are defined as lines that extend in one direction without curving or bending. In geometry, a straight line is the shortest distance between two points. They have a constant direction and do not change in orientation.
So it’s kind of a complicated process, but here’s the two-sentence version: Lightning is an electric current that takes the path of least resistance from the base of a cloud to the ground. Since the air it travels through is not uniform—variations in things like temperature, humidity, and pollutants determine how resistant air is to the charge—the lightning has to zig and zag to stay on that path.
It does not, it travels as a wave

Ibn al-Haytham, also known as Alhazen, was the Muslim scientist who discovered that light travels in a straight line. His work on optics and the nature of light significantly influenced the development of the scientific method in early Islamic science.
Visible light travels in a straight line unless it encounters obstacles or mediums that cause it to bend or scatter.
Light the electromagnetic wave.
Light typically travels in a straight line, as described by the principle of rectilinear propagation. However, it can be affected by gravitational fields or optical illusions that may make it appear otherwise.
Yes, a shadow is proof that light travels in a straight line because shadows are formed when an object blocks light that is traveling in a straight path from the source to the surface where the shadow is cast. If light did not travel in a straight line, shadows would not form as they do.

The observation that light travels in a straight line can be explained by the property of light known as rectilinear propagation. This property states that light travels in a straight line in a homogenous medium.

A laser
Light travels in a straight line, moving in a straight path known as a ray.
