Calculate the Energy of a Photon Every object gets its color by reflecting a certain portion of incident light. The color is determined by the wavelength of the reflected photons, thus by their energy. What is the energy of a photon from the violet portion of the Sun’s light if it has a frequency of 7.230 × 1014 s -1?
(a)
Calculate the energy possessed by a single photon of each of the following types of electromagnetic radiation.
6.32 × 1020 s –1
(a)
Calculate the energy possessed by a single photon of each of the following types of electromagnetic radiation.
9.50 × 10 13 Hz
(a)
Calculate the energy possessed by a single photon of each of the following types of electromagnetic radiation
1.05 × 1016 s –1
(a)
The energy of photoelectrons emitted from a metal surface can be increased by
using light of higher frequency.
using light of longer wavelength.
using light of higher intensity.
using monochromatic, polarized light.
What happens to the light emitted by a heated, glowing object as its temperature increases?
Color of light changes as the object requires more energy
Color of light stays the same
