Many people contributed to the knowledge of the nature of light - some proving that it behaved as a stream of particles, others proving that it behaved as a wave.
A light source made from nature could be sunlight streaming through a window or firelight from a campfire. Alternatively, bioluminescent organisms like fireflies or certain types of algae can also serve as natural light sources.
Roemer deduced the speed of light to be approximately 220000 km/s. By observing the delay in the light from Jupiter's moon during its eclipses, he calculated the time it took for light to travel the diameter of Earth's orbit. This method resulted in an estimated speed of light.
Yes, the sun is part of nature. It is a natural astronomical entity and plays a crucial role in the Earth's ecosystem by providing light and energy for life to thrive.

Examples of luminous objects found in nature include the sun, bioluminescent organisms like fireflies and some types of jellyfish, and certain minerals that exhibit fluorescence or phosphorescence under ultraviolet light.
Light waves are transverse in nature.
The particle nature of light is illustrated by the photoelectric effect.
transverse nature of light is verified by polarisation.
Conclusion
Light is transverse in nature, meaning its waves oscillate perpendicular to the direction of its propagation.
Textures are how surfaces feel. Textures are described by how they feel to the touch (rough, scaly, smooth). If you can't touch an object, the texture can be deduced by looking at how light hits it.
The photoelectric effect does not support the wave nature of light. This phenomenon can only be explained by the particle nature of light, as described by Albert Einstein in his theory of photons.
Light being electromanetic wave is TRANSVERSE in nature.
Albert Einstein's Photo-electric effect is one of the proof of the particle nature of light. The experiment on the wave particle duality is another proof pf the particle nature of light.
