Has anyone ever come across any experiments suggesting that the E=hw law for the energy of photons may require some correction, especially in the case of low energy photons ?
Yes, the equation E=hw, also known as the Planck-Einstein relation, is always true. It is a fundamental law of physics that describes the relationship between energy (E) and frequency (w) of electromagnetic radiation, such as light.
The equation E=hw was discovered by German physicist Max Planck in 1900 and later refined by Albert Einstein in 1905. Planck proposed that energy is quantized, meaning it can only exist in discrete units, and that the energy of each unit is proportional to the frequency of the radiation. Einstein further developed this idea by introducing the concept of photons, which are individual packets of energy.
Yes, E=hw can be applied to all forms of energy, as long as they involve electromagnetic radiation. This includes visible light, radio waves, x-rays, and more.
E=hw is significant because it helped explain the behavior of electromagnetic radiation and led to the development of quantum mechanics. It also has many practical applications, such as in the development of technologies such as lasers, solar cells, and LED lights.
There are no known exceptions to E=hw. However, it is important to note that this equation is a simplified version of the more comprehensive and complex quantum mechanics equations, which take into account factors such as the wave-particle duality of light and the uncertainty principle. In extreme conditions, such as near black holes, E=hw may not accurately describe the behavior of energy.
