What is the energy of a photon that has a wavelength of 444 nm?

What is the energy of a photon that has a wavelength of 444 nm?

The photon’s wavelength is 444 nm. The maximum frequency is 7.50 x 1014 Hz. Each photon has an energy of 2.47 eV.

What is the energy of a 500 nm photon?

Question: The energy of a 500 nm photon is 4 x 10−19 J.

What is the energy in joules of a photon of 710 nm?

=1.29077⋅10−18 Joules.

What is the energy of the photon emitted?

The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level. When the electron changes from n=3 or above to n=2, the photons emitted fall in the Visible Light region of the spectra.

How to calculate the energy of a photon of green light?

Calculate the energy, in joules, of a photon of green light having a wavelength of 562nm? The answer is 3.54 ×10−19 J. The equation for determining the energy of a photon of electromagnetic radiation is E = hν, where E is energy in Joules, h is Planck’s constant, 6.626 × 10−34J ⋅ s, and ν (pronounced “noo”) is the frequency.

What is the wavelength of a photon?

Now, notice that you are given the wavelength of the photon, λ. As you know, frequency and wavelength have an inverse relationship described by the equation Another important thing to notice here is that the wavelength of the photon is given in nanometers, nm.

What is the energy of a photon proportional to its frequency?

The energy of a photon is proportional to its frequency, as stated by the Planck – Einstein’s equation. #color(blue)(E = h * nu)” “#, where. #E# – the energy of the photon. #h# – Planck’s constant, equal to #6.626 * 10^(-34)”J s”#.

What is the relationship between wavelength and frequency in nanometers?

You have been given the wavelength λ (pronounced lambda) in nanometers, but not the frequency. Fortunately, a relationship between wavelength, frequency, and the speed of light, c exists, such that c = λ ⋅ ν. To determine the frequency from the wavelength, divide c by λ:
