It would be interesting to have a forum where the first response to any question ran through something like ChatGPT.
If that was incorrect or if there were still any questions the human forum members would jump in.
In this case (and in most cases) there would just be one response needed.

Light waves are transmitted across space through a medium called the electromagnetic field. In a vacuum, which is a near-empty space, light waves can propagate without the need for a physical medium. This is because light is composed of self-propagating electric and magnetic fields that interact with each other, creating electromagnetic waves.
Distinguishing light from the information it carries can sometimes be challenging. The information contained in light is typically extracted through its interaction with a detecting system, such as our eyes or specialized instruments. We interpret the properties of light, such as its intensity, color, and polarization, to extract information about the objects or phenomena that emitted or interacted with the light.
Light that doesn't carry any discernible information would essentially be random or uniform in its properties. It would lack any distinguishable patterns or variations that could be used to convey meaningful information.
The amount of information that a light wave can carry depends on various factors, including its bandwidth, intensity, modulation scheme, and encoding techniques. Information capacity is often quantified using concepts like data rate (bits per second) or channel capacity (maximum achievable data rate).
Each wave of light can correspond to many photons. In classical physics, light is described as an electromagnetic wave, and the energy it carries is distributed continuously throughout the wave. However, in quantum physics, light is also considered to be made up of discrete particles called photons. The relationship between light waves and photons is described by wave-particle duality.
The information carried by a light wave and a photon can be considered the same in some cases. For example, in communication systems using photons, the information encoded in the light wave is typically encoded in individual photons. However, in other scenarios, such as spectroscopy or quantum information processing, the distinction between the information carried by a light wave and a single photon becomes more significant.
When a light wave is absorbed into matter, its energy is transferred to the absorbing material. The energy can cause various effects depending on the specific interaction. For example, it may be converted into heat, chemical reactions, or the excitation of electrons in atoms or molecules. The information carried by the light wave can be used to induce changes or provide input to the receiving system, leading to different physical or chemical processes."
