What is the effect of absorbing photons of energy on ozone?
Absorbing photons of energy can break apart ozone molecules in the stratosphere, resulting in an increase in oxygen molecules and a decrease in ozone concentration. This process can contribute to ozone depletion, allowing more harmful ultraviolet radiation to reach the Earth's surface.
What color is the radiative zone?
The radiative zone of the Sun is not visible to the human eye, so it does not have a color. It is located beneath the Sun's visible surface where energy is transported by photons through a process of radiative diffusion.
When electromagnetic radiation strikes the surface of a metal electrons are ejected from the metal's surface what is the description?
This phenomenon is known as the photoelectric effect. When electromagnetic radiation, such as light, strikes a metal's surface, it can transfer energy to the electrons in the metal. If the energy of the incoming photons is sufficient to overcome the metal's work function, the electrons are ejected from the surface. This effect demonstrates the particle-like behavior of light and supports the concept of quantized energy levels in atoms.
Is is true that the frequency of photons must be larger than a certain minimum value in order to eject electrons from the metal?
Yes, that is true. This minimum frequency is called the threshold frequency and is determined by the work function of the material. Photons with frequencies lower than the threshold frequency do not carry enough energy to eject electrons from the metal surface, even if the intensity of light is high.
Why alkali metals used in photoelectric effect?
Alkali metals are used in the photoelectric effect because they have low ionization energies, making it easier for photons to eject electrons from their surface. This makes them efficient materials for producing a photoelectric effect. Additionally, alkali metals have a clean surface that allows for reliable and consistent results in experiments.
What are particles that move quickly away from the sun's surface called?
Photons. (In the form of electromagnetic radiation)
What color are most of the photons that leave the Sun's surface?
The majority of photons leaving the Sun's surface are in the visible spectrum, with a peak intensity in the green region. This is why the Sun appears white when viewed from space, as it emits light across all visible wavelengths.
What colors are green surfaces reflecting?
Green surfaces are absorbing all other color photons, and reflect only green photons, making the surface appear as green.
Why does violet light eject electrons from a certain photosensitive surface whereas red light has no effect on that surface?
Violet light has higher energy photons compared to red light. This higher energy allows violet light photons to transfer enough energy to electrons in the photosensitive surface to eject them, a process known as the photoelectric effect. Red light photons do not have enough energy to overcome the work function of the surface and therefore cannot eject electrons.
What objects emit photons on the striking of radiation on their surface?
a rare french cheese by the name of gullible
How long does it take Photons at the core to the surface?
It can take thousands to millions of years for a photon to travel from the core of the Sun to its surface due to the dense interactions and scattering of photons within the Sun's outer layers. Once a photon reaches the surface, it takes only about 8 minutes to travel to Earth.
How many photons are there in a beam of light?
More than 1. Describing the intensity of the beam will establish the number of photons per second striek a perpendicular surface of a given area.
What is the effect of absorbing photons of energy on ozone?
Absorbing photons of energy can break apart ozone molecules in the stratosphere, resulting in an increase in oxygen molecules and a decrease in ozone concentration. This process can contribute to ozone depletion, allowing more harmful ultraviolet radiation to reach the Earth's surface.
KE equals hf minus hfo what does hf stand for?
hf is the energy of photons incident on the surface
How did Albert Einstein explain photoelectric effect?
Apex Light is made of photons.
What happens to photons and photoelectrons when you double the amount of light shining on the metal?
If you double the amount of light shining on a metal, you will increase the number of photons hitting the metal surface. This can lead to more photoelectrons being ejected from the metal due to the increased energy provided by the additional photons.
What is The path of the photons through the suns plasma is called?
The path of photons through the Sun's plasma is called radiative diffusion. Photons travel through the Sun's plasma by bouncing off charged particles in a random walk pattern until they reach the surface and are emitted as sunlight.
