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)

The principle that light travels in straight lines was first proposed by the ancient Greek philosopher Euclid in his work "Optics." Euclid's ideas were further developed by Islamic scientist Ibn al-Haytham in the 11th century, who is often credited with the discovery that light travels in straight lines.
Light travels in electromagnetic waves, which are a type of transverse wave. These waves consist of oscillating electric and magnetic fields that propagate through space at the speed of light.
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.
Yes, light generally travels in a straight line in a uniform medium like air or a vacuum. This is known as rectilinear propagation. However, light can bend or refract when it passes through different mediums with varying densities.
