Wavelegnth, Frequency and Energy Calculations

There were discrete values of energy that differed by this constant. In other words, all energy is a multiple of this constant multiplied by the frequency of the wave of light. Energy is therefore quantized, it is always a multiple of a single packet of energy. Now on to the equations.

Constants and Equations – EWT – Energy – Energy Wave

** Derived Constants – the derivations for the constants are: In Energy Wave Equations: Correction Factors, a potential explanation for the values of these g-factors is presented as a relation of Earth’s outward velocity and spin velocity against a rest frame for the universe. A velocity of 3.3 x 10 7 m/s (11% of the speed of light) would reduce three g-factors to one based on relativity principles.

Equation (6) shows that E(t) is a constant so that E(t) = E(0) = ˆ 2 R L 0 g(x)2 dx+ ˝ 2 R L 0 f0(x)2 dxwhere (2) has been used. We can derive equation (3) in a more general context by starting with the kinetic energy ie: KE= ˆ 2 Z 1 1 @u @t 2dx (7) To get convergence of the integral we have to assume that the integrand vanishes outside of some large interval jxj R.

Basic Wave Parameters. The total energy will equal the maximum kinetic energy. Combining these two results: The Impedance of the medium (called the Specific Acoustic Impedance in Acoustics) is defined by the product of density and wave speed. In symbols: Impedance, z = ρc with a unit of Pa.s.m -1.

Wave energy and wave-energy flux. The potential energy density is equal to the kinetic energy, both contributing half to the wave energy density E, as can be expected from the equipartition theorem. In ocean waves, surface tension effects are negligible for wavelengths above a few decimetres .

Wave Power: Theory Behind Ocean Waves

Wave energy. In average ocean conditions, the average energy density per unit area of sea surface waves is proportional to the wave height squared, shown in the following equation: where E is the mean wave energy density per unit horizontal area (J/m2), the sum of kinetic and potential energy density per unit horizontal area.

Calculating Energy of a Wave – Physics Stack Exchange

Calculating Energy of a Wave. In my notes, the energy of a wave is directly proportional to the square of the amplitude, ie. E∝A2 However, I recalled that, in one of my physics lessons, our physics teacher told us that the energy of a wave can be calculated using E=hf, where h is the Planck constant and f …

Both the equations you cite are correct. The energy carried by a wave is indeed proportional to the amplitude squared. for what it’s worth, you don’t even need a propagating wave, any harmonic oscillator (e.g. a pendulum) will follow that rule. The validity of this rule remains unaffected even in quantum mechanics (actually, since in QM everything can be described by a wave function, it is even more fundamental there). The second formula expresses the energy of a single photon. A photon is the smallest quantity of radiation that can exist at that frequency. This is completely unrelated to the total energy of the wave! For instance even a small light bulb will emit something like $10^{20}$ photons each second. Each carries an energy of $hf$. Together they sum up to the total power of the beam.Best answer · 6You are mixing classical mechanics with quantum mechanics. In QM, a photon has a wavelength and a frequency, but it isn’t a “wave”. It will never be seen on an oscilloscope because of various quantum mechanical oddities like superposition, entanglement, etc., which are completely foreign to classical mechanics. Nobody yet knows how to combine classical mechanics and quantum mechanics into a single theory. It will almost certainly require a rewrite to both of them. There is much discussion and little progress in this area. Classical mechanics is solely statistical in nature–it is an analysis of the “average” behavior of many quantum mechanical systems. QM is also statistical only because we don’t yet understand the exact reasons behind individual (quantum) interactions, and if there even are any, so it talks about probability of an interaction taking place. Anyway, a classical wave’s energy is proportional to the square of its amplitude. For example, classically speaking the energy in an electromagnetic wave is proportional to the square of its peak electric field, or you an say its proportional to the square of its peak magnetic field. However, in the last hundred years or so we’ve discovered that the EM field is quantized, and that the “wavelength” of each quanta is inversely proportional to that quanta’s energy. We measure wavelength in, for example, double slit experiments. But we never see the wave of a single photon on an oscilloscope. You can have a lot of low frequency photons with some total energy, and have fewer high frequency photons with the same energy. Classically they have the same peak electric field, but one has fewer photons than the other.0But, I should add that an intense wave of low-frequency photons may have the same electric and magnetic field strengths as a less-concentrated wave of gamma-rays, but they don’t ‘react’ with matter in the same way necessarily. Since atoms/molecules deal with one photon at a time, even an powerful laser of IR photons won’t ionized them like a gamma ray would. I think.0

This equation allows us to calculate the energy of photons, given their frequency. If the wavelength is given, the energy can be determined by first using the wave equation (c = × ) to find the frequency, then using Planck’s equation to calculate energy. Use the equations above to answer the following questions.
