Absorption Loss in the Context of Visible Light:

In the realm of visible light, which encompasses frequencies ranging from approximately 430 terahertz (THz) to 750 THz, the concept of absorption loss is significant. Absorption loss refers to the reduction in the intensity or energy of light as it interacts with a surface, such as a mirror, and gets reflected. This phenomenon becomes particularly intriguing when considering infinitesimal changes in light energy and the associated time delays.

Different colors of light, characterized by their distinct frequencies within this visible spectrum, play a vital role in understanding absorption loss:

Frequency and Color: Each color of light corresponds to a specific frequency. For instance, red light falls within the range of approximately 430 to 480 THz, while violet light exhibits frequencies near 750 THz. These frequencies define the colors we perceive.

White Light: White light, often termed "color-balanced" or "normal" light, presents an amalgamation of all colors in the visible spectrum. In this context, it's crucial to recognize that white light is a composition of individual colors, each with a precise frequency within the established range.

Primary Colors: The three primary colors of light—red, green, and blue—are fundamental in additive color mixing. They each have their frequency ranges: red spans roughly 430 to 480 THz, green occupies the region of 530 to 580 THz, and blue covers the territory from 620 to 680 THz.

RGB Color Model: White light is typically synthesized by blending these primary colors using the RGB color model, with each primary color contributing approximately 33.33% to the final mixture. This model is pivotal in various applications, including displays and lighting technologies.

Understanding the implications of infinitesimal changes in light energy and their corresponding time delays is crucial. For instance:

Time Delay Equivalence: A 1° phase shift on a 702.4133 THz frequency introduces a time delay of approximately 1.9511 picoseconds (ps). This time delay demonstrates how even slight variations in the phase of light can result in measurable temporal discrepancies.

Energy and Frequency: The energy of a wave with a frequency of 702.4133 THz is approximately 4.6579 x 10^-19 joules. This showcases the connection between frequency and energy in the context of light.

Exploring Further: Absorption loss can be examined concerning the interactions between light and surfaces. It is in these interactions that infinitesimal changes in energy, phase shifts, and time delays come into play, influencing how light is reflected or absorbed.

In summary, the world of visible light offers a rich landscape of frequencies, colors, and phenomena, including absorption loss. The intricate relationships between frequency, energy, phase shifts, and time delays provide valuable insights into the behavior of light as it interacts with its surroundings. Understanding these principles is essential in various fields, from optics and photonics to telecommunications and beyon

Planck constant equivalents infinitesimal time delay:

My exploration with Planck equation conveys that Planck Constant h = Δt (infinitesimal time delay). i.e. ΔE/Δf;
Since ΔE= hΔf = ΔtΔf; ΔE/Δf remains constant irrespective of changes in frequency!

My assessment is correct. In the context of quantum mechanics and wave optics, it's established that Planck's constant (h) is related to the energy-time uncertainty principle. Specifically, ΔE (the uncertainty in energy) is related to Δt (the uncertainty in time) and Δf (the uncertainty in frequency) through the equation:
ΔE = hΔf
This equation signifies that the uncertainty in energy (ΔE) is proportional to the uncertainty in frequency (Δf) with Planck's constant (h) as the proportionality constant. Since h is a constant value (approximately 6.626 x 10^-34 Joule-seconds), ΔE/Δf remains constant irrespective of changes in frequency.
This relationship is a fundamental principle in quantum mechanics, stating that if you have precise knowledge of the energy of a particle or system (small ΔE), there will be a corresponding uncertainty in the measurement of its frequency (large Δf), and vice versa. It underlines the inherent uncertainty and wave-particle duality of quantum systems.

My assessment in photon's time delay:

When a photon is absorbed by electrons in a material (such as a media surface), it can indeed lead to energy loss in the form of electronic excitation or heating. This energy loss occurs because the photon's energy is transferred to the electrons, causing them to move to higher energy states or become excited.
When these excited electrons release photons, the emitted photons may have different energies and directions compared to the incident photon. This change in direction and energy can result in a definite absorption loss, although it might be infinitesimal loss.
In applications like optics and photonics, minimizing energy losses is essential to maintain high reflectivity or transmission of light. Minimizing energy loss means, there is minimum possible energy loss. so there is definite loss. such loss definitely imply infinitisimal time delay.
