So, I've learned in school that the energy of a wave is proportional to the square of its amplitude. I've also learned that the energy of light is given by E= hv. I'm confused. Could someone clarify?
More precisely, energy of a photon with frequency ##\nu##. For classical lightwave, the energy is the sum of all these quanta present in there.UncertaintyAjay said:I've also learned that the energy of light is given by E= hv. I'm confused
What is proportional to the intensity? The energy?, Electromagnetic wave's energy is in general not proportional to its intensity, instead it's the integral of intensity over space and time.UncertaintyAjay said:And hence proportional to intensity?
I'm having a bit of trouble visualising exactly what you mean by over space and time. Could you give me an example?blue_leaf77 said:What is proportional to the intensity?

Wave energy is the energy carried by waves in the ocean. It is a renewable and sustainable form of energy that can be harnessed to generate electricity.
Light energy is a form of electromagnetic radiation that is visible to the human eye. It is a type of energy that can be seen as light and is responsible for allowing us to see the world around us.
The main difference between wave energy and light energy is the type of energy they carry. Wave energy is a form of mechanical energy, while light energy is a form of electromagnetic energy. Additionally, wave energy is primarily found in the ocean, while light energy is present all around us.
Wave energy can be converted into usable energy through the use of various technologies, such as wave energy converters. These devices capture the energy of ocean waves and convert it into electricity, which can then be used to power homes and buildings.
Yes, wave energy is considered a viable source of renewable energy. It is a clean and sustainable form of energy that has the potential to meet a significant portion of the world's electricity needs. However, further research and development are needed to make it more cost-effective and widely available.
