What is the photon energy of red light having wavelength 640 nm?

The photon energy of red light with a wavelength of 640 nm is approximately 1.94 eV (electron volts). This can be calculated using the formula E = hc/λ, where h is Planck's constant, c is the speed of light, and λ is the wavelength of the light.


What is the energy of a 500 nm photon?

The energy of a 500 nm photon is 3.1 eV (electron volts). This is a unit of measure used to represent the energy of a single photon. To put this into perspective, a single photon of visible light has an energy of 1.8 to 3.1 eV, and a single photon of ultraviolet light has an energy of 3.1 to 124 eV. The energy of a 500 nm photon can be calculated by using the following equation: E = hc/ Where: E = energy of the photon (in eV) h = Planck's constant (6.626 * 10-34 Js) c = speed of light (2.998 * 108 m/s) = wavelength of photon (in meters) Therefore, the energy of a 500 nm photon is calculated as follows: Convert the wavelength from nanometers to meters: 500 nm = 0.0005 m Insert the values into the equation: E = (6.626 * 10-34 Js) * (2.998 * 108 m/s) / (0.0005 m) Calculate the energy: E = 3.1 eVTherefore, the energy of a 500 nm photon is 3.1 eV.


What is the difference between electron volts and volts in terms of measuring energy?

Electron volts (eV) and volts (V) are both units of energy measurement, but they are used to measure different types of energy. Volts measure the electrical potential difference between two points, while electron volts measure the energy of particles, such as electrons, in an electric field. In simpler terms, volts measure electrical potential, while electron volts measure the energy of particles in that potential.

If the inner accretion disk around a black hole has a temperature of 1000000 K at what wavelength will it radiate the most energy?

For a thermal radiation source, the peak of the blackbody radiation curve is at a photon energy 2.8 times the temperature in electron-volts. The temperature in electron-volts is 1/11,600 times the temperature in Kelvin. Use E = hv to convert from the photon energy (E) to photon frequency, using Plank's constant h. Use v = c/(lambda) to convert from the photon frequency to the wavelength. The result: these hot plasmas radiate X-rays, and the peak wavelength is about 50 Angstroms, i.e. 5 nm.


When hydrogen electrons goes from n equals 3 to n equals 1 what happens?

When an electron goes from a higher state to a lower state, it gives up energy equal to the difference of energy levels of the two states. This energy is in the form of a photon. If it goes directly from n=3 to n=1, then 1 photon is emitted. If it transitions from n=3 to n=2, then from n=2 to n=1, two (2) photons are emitted. Energy level of n=3 for Hydrogen is -1.511 eV (electron volts) Energy level of n=2 for Hydrogen is -3.4 eV (electron volts) Energy level of n=3 for Hydrogen is -13.6 eV (electron volts) The energy levels are 'more negative' at lower levels because the electron becomes more bound to the atom. From n=3 to 1 (gives up 12.089 eV, or a photon with wavelength 102.518 nm - ultraviolet light) From n=3 to 2 (gives up 1.889 eV, or a photon with wavelength 656.112 nm - red light) From n=2 to 1 (gives up 10.2 eV, or a photon with wavelength 121.5 nm - ultraviolet) See related link post.

If an electron and photon both have energy of 5 mega electron volt which will cause pair production?

pair production only occurs with photons. The necessary condition is that the energy of the photon is greater than that of the two particles that are going to be produced. With 5 mega electron volts as an energy your photon would still not have enough juice as the two smallest particles that can be build are electron and its anti patricle the positron. Both have 511 MeV. You are looking at a trickquestion as neither can.


What is the highest energy photon that can be absorbed by a ground-state hydrogen atom without causing ionization?

The highest energy photon that can be absorbed by a ground-state hydrogen atom without causing ionization is the photon energy equivalent to the ionization energy of hydrogen, which is approximately 13.6 electron volts. This is the energy required to completely remove the electron from the atom. Any photon with higher energy would cause ionization of the hydrogen atom.
