Is the energy of photon equal to frequency?
The energy E of a photon is equal to hv = hc/λ, where v is the frequency of the electromagnetic radiation and λ is its wavelength. The most energetic electrons inside a given metal are bound to that metal by an amount of energy called the work function ϕ of that particular metal.
What is the relationship between frequency wavelength and photon energy of the electromagnetic wave?
The photon model equation relates the frequency and energy of a photon together by a constant of proportionality, where E∝f⇒E=hf , where: E is the energy of the photon ( J ) f is the frequency of the photon ( s−1 ) h is Plank’s constant ( ≈6.63⋅10−34Js )
What is the relationship of frequency and energy of an electromagnetic wave?
The energy of a photon is directly proportional to the frequency of the radiation, with a constant of proportionality called Planck’s constant. That is, E = hν, where h = 6.626 × 10−34 J/s and the energy is in Joules.
Does photon energy depend on frequency?
The energy of the photon depends on its frequency (how fast the electric field and magnetic field wiggle, this needs better wording, for ‘fast electric field’ and ‘wiggle’). The higher the frequency, the more energy the photon has. Of course, a beam of light has many photons.
Is frequency the energy of a wave?
The amount of energy they carry is related to their frequency and their amplitude. The higher the frequency, the more energy, and the higher the amplitude, the more energy.
What is the relationship between frequency and wavelength frequency and energy wavelength and energy?
Just as wavelength and frequency are related to light, they are also related to energy. The shorter the wavelengths and higher the frequency corresponds with greater energy. So the longer the wavelengths and lower the frequency results in lower energy. The energy equation is E = hν.
What is the relationship between wavelength and frequency energy?
The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer.

What equation calculates the energy of a photon?
E=hf=hcλ(energy of a photon) E = h f = h c λ (energy of a photon) , where E is the energy of a single photon and c is the speed of light. When working with small systems, energy in eV is often useful. Note that Planck’s constant in these units is h = 4.14 × 10−15 eV · s.
