How does an increase in the intensity affect the maximum kinetic energy of the photoelectrons?
An increase in the intensity of light does not affect the maximum kinetic energy of photoelectrons. The maximum kinetic energy of photoelectrons is determined by the frequency of the incident light, according to the photoelectric effect equation E = hf - φ, where f is the frequency of the light and φ is the work function of the material.
Light with an energy equal to three times the work function of a given metal causes the metal to eject photoelectrons. What is the ratio of the maximum photoelectron kinetic energy to the work functio?
The maximum photoelectron kinetic energy is given by the equation: Energy of incident light - Work function. If the energy of the incident light is three times the work function, then the maximum kinetic energy of the photoelectrons will be three times the work function. Therefore, the ratio of the maximum photoelectron kinetic energy to the work function is 3:1.
Which best describes the relationship between photon energy and the color of light?
The color of light is directly related to the energy of its photons. Light with higher photon energy appears bluer, while light with lower photon energy appears redder. This relationship is governed by the electromagnetic spectrum and the frequency of light.
What color is light that has an energy of 3.25x10-19 J?
The color of light does not depend on its energy. The energy level provided is very low and falls within the range of the infrared spectrum.
When light shines on a metal surface the maximum energies of emitted electrons?
depend on the frequency of the incident light. The maximum energy of emitted electrons is given by the equation E = hf - φ, where E is the maximum energy, h is Planck's constant, f is the frequency of the incident light, and φ is the work function of the metal.
How can you tell the energy released based on the color of the light?
The frequency of the light is the color and the energy is E=hf or Planck's Constant times the color or frequency.
What color of the visible light spectrum has the highest energy?
Violet light has the highest energy.
How does the wavelength of maximum absorbance relate to the color of a substance?
The wavelength of maximum absorbence relates to the color, because the only color that is not absorbed will be the color of the item. For example, plants are green because they absorb red and blue light, and reflect green light.
How does an increase in the intensity affect the maximum kinetic energy of the photoelectrons?
An increase in the intensity of light does not affect the maximum kinetic energy of photoelectrons. The maximum kinetic energy of photoelectrons is determined by the frequency of the incident light, according to the photoelectric effect equation E = hf - φ, where f is the frequency of the light and φ is the work function of the material.
What color should a room be painted to save energy?
Try light color that let in light so that your bulb wont have to produce as much energy to light up a room.

The color of light does not depend on its energy. The energy level provided is very low and falls within the range of the infrared spectrum.
What color carries the least amount of energy?
red light has the least energy of any visible (to humans) color, and violet has the most energy. The amount of energy carried by light is directly proportional to its frequency; the higher the frequency, the more energetic the light is.
How much energy does a yellow light color have?
500kj

Which color will have the longest wavelength which corresponds to the lowest energy?
Red
