What is the energy of a photon of blue light?
Red photons of light carry about 1.8 electron volts (eV) of energy, while each blue photon transmits
about 3.1 eV
.
How do you calculate the energy of a photon of blue light?
Explanation: To find energy, you must know the frequency of the light. Since we are given wavelength we can use this equation:
c= λ v
where c is the speed of light (3 x 108 m/s), λ is the wavelength, and the v is the frequency (units: 1/s).
What is the energy of a blue photon of wavelength 400 nm?
Solution: From the previous problem, the energy of a single 400 nm photon is
3.1 eV
. One must therefore reduce the effective work function to 3.1 eV to allow the light to liberate an electron.
How much energy is in a photon with a 450 nm wave?
Energy of a blue photon: E=6.62×10-34x750x1012 =
6.62×10-22 joule
.
What are the longest wavelengths?
As the full spectrum of visible light travels through a prism, the wavelengths separate into the colors of the rainbow because each color is a different wavelength. Violet has the shortest wavelength, at around 380 nanometers, and
red
has the longest wavelength, at around 700 nanometers.
What is the energy on one photon of blue light at 465nm?
Electromagnetic radiation with a wavelength of 465 nm appears as blue light to the human eye. The energy of one photon of this light is
4.27 x 10^-19 J.
