Mass of a photon defines its energy, not the reverse. E = mc^2 = ( 7.3724973e−51 kg ) × ( 299792458 m/s ) 2 = 6.62607015e−34 J

 

The True Essence of Photon Energy: Mass as the Fundamental Property

In the realm of physics, the interplay between mass and energy has long captivated scientists. While energy is often treated as a primary quantity, a closer examination reveals that it is mass that fundamentally defines a photon's energy. This shift in perspective unveils the deep-rooted connection between mass, energy, and the fabric of spacetime.

Mass of a 1 Hz Photon: The Fundamental Property

Consider a photon with a frequency of 1 Hz. Using the formula derived from Einstein's and Planck's work, we calculate its mass:

$$m=\frac{hf}{c^2}m\; =\; \backslash frac\{hf\}\{c^2\}$$

For a 1 Hz photon, this translates to:

$$m=\frac{6.62607015\times 10^{-34}\text{ J s}}{(2.99792458\times 10^8\text{ m/s}{)}^2}=7.3724973\times 10^{-51}\text{ kg}m\; =\; \backslash frac\{6.62607015\; \backslash times\; 10^\{-34\}\; \backslash text\{\; J\; s\}\}\{(2.99792458\; \backslash times\; 10^8\; \backslash text\{\; m/s\})^2\}\; =\; 7.3724973\; \backslash times\; 10^\{-51\}\; \backslash text\{\; kg\}$$

This mass is not an abstract concept but a tangible, measurable quantity that defines the photon's interaction with spacetime.

Energy Derived from Mass

The renowned equation $E=m{c}^{2}E\; =\; mc^2$ illustrates that energy is intrinsically linked to mass. For our 1 Hz photon, its energy can be expressed as:

$$E=m{c}^{2}E\; =\; mc^2$$

Plugging in the values, we get:

$$E=(7.3724973\times 10^{-51}\text{ kg})\times (2.99792458\times 10^8\text{ m/s}{)}^2=6.62607015\times 10^{-34}\text{ J}E\; =\; (7.3724973\; \backslash times\; 10^\{-51\}\; \backslash text\{\; kg\})\; \backslash times\; (2.99792458\; \backslash times\; 10^8\; \backslash text\{\; m/s\})^2\; =\; 6.62607015\; \backslash times\; 10^\{-34\}\; \backslash text\{\; J\}$$

This calculation shows that the energy of a 1 Hz photon, which is Planck's constant $hh$, is directly derived from its mass.

Decoding Planck's Constant ($hh$)

Planck's constant ($hh$) encapsulates the mass of a 1 Hz photon along with $c^{2}c^2$, demonstrating the primary role of mass. The formula:

$$h=m\cdot c^{2}h\; =\; m\; \backslash cdot\; c^2$$

reveals that $hh$ is essentially the product of the photon's mass and the speed of light squared. This highlights that mass is the fundamental property, while energy is a derived concept.

The Primacy of Mass in Defining Photon Properties

Understanding that mass is the primary property of photons helps clarify their interaction with spacetime. As photons move along their worldlines, their invariant mass interacts with the curvature of spacetime, defining their observed properties such as energy and momentum.

Conclusion

Revisiting our understanding of photons and recognizing mass as the fundamental property can lead to a deeper comprehension of the universe. By seeing energy as a derived quantity, we unveil the true essence of the relationship between mass, energy, and spacetime. This perspective not only aligns with foundational physics but also paves the way for future discoveries and innovations.

Embracing this simple yet profound truth brings us closer to unraveling the mysteries of the cosmos, and highlights the elegance and interconnectedness of the fundamental laws that govern our reality.
