What else can I help you with?
Light is made of elementary particles called what?
Well, they're probably not really particles ... but they're called "photons".
Are electrons moving through space called light?
No, electrons moving through space are not called light. Light is electromagnetic radiation that is made up of photons, while electrons are negatively charged subatomic particles found in atoms. Moving electrons can produce light when they transition between energy levels in an atom, but they are not the same as light itself.
When excited electrons return to lower energy levels what is released?
When excited electrons return to lower energy levels, they release energy in the form of photons. This process is known as emission of light or fluorescence. The energy of the emitted photons corresponds to the energy difference between the higher and lower energy levels of the electrons.
Which color will have the longest wavelength which corresponds to the lowest energy?
Red
How is light energy transferred into an object and converted into thermal energy?
Light energy is transferred into an object when photons from the light source are absorbed by the object's surface. The absorbed photons increase the kinetic energy of the object's molecules, causing them to vibrate and generate heat, which is thermal energy.
What you the no of photons of light with wave 4000 pm that provided 1J energy?
To calculate the number of photons that provide 1J of energy for light with a wavelength of 4000 pm, we need to use the formula E=nhf, where E is the energy, n is the number of photons, h is the Planck's constant, and f is the frequency. First, calculate the frequency using the speed of light formula, c=λf. Then, calculate the energy per photon using E=hf. Finally, divide the total energy by the energy per photon to find the number of photons.
What is the no of photons of light with wave 4000 pm that provided 1J energy?
To calculate the number of photons, you can use the formula: Energy of 1 photon = hc / λ where h is Planck's constant, c is the speed of light, and λ is the wavelength. From this, you can determine the energy of one photon of light with a 4000 pm wavelength and then calculate the number of photons required to provide 1 Joule of energy.
Which has a lower amount of energy red light or blue light?
Red light has a lower amount of energy than blue light. This is because red light has a longer wavelength, which corresponds to lower energy photons, while blue light has a shorter wavelength and higher energy photons.
Why are the photons that emerge from the Sun's surface visible-light photons and infrared-light photons rather than gamma-ray photons?
Photons do not come in different types like infared-photons etc. they are just the wavelength that the photons are at and nuclear fusion just happens to emit photons at a particular wavelength
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.
How is intensity of light related to photons?
The intensity of light is directly related to the number of photons present. Higher intensity light has more photons, while lower intensity light has fewer photons. Each photon detected carries a discrete amount of energy that contributes to the overall intensity of the light.
How many photons are contained in a flash of green light 525nm that contains 189KJ of energy?
To find the number of photons, we need to first calculate the energy of one photon using the formula E = hc/λ, where E is energy, h is Planck's constant, c is the speed of light, and λ is the wavelength. Then, we can divide the total energy (189 kJ) by the energy of one photon to get the total number of photons in the flash of light.
When comparing a beam of red light and a beam of green light which beam contains the greater number of photons?
Neither. The beams of red light and green light will have the same number of Photons, as energy is only related to frequency. The number of Photons is dependent on the intensity of the light beams.
What do light sensors do?
Light sensors measure the number of photons or the energy of light hitting the sensor.
Is there more photons in brighter light?
Yes, brighter light typically means more photons are present because brighter light has a higher intensity, which is measured by the number of photons hitting a given area over time. So, in a brighter light source, there are indeed more photons emitted.
If the light bulb from number 10 radiates 100 watts times 100 joules per second of photons. How many photons per second are radiated?
To find the number of photons being radiated per second, you need to calculate the energy of each photon first. Since the light bulb emits 100 watts (100 joules per second), and each photon has an energy of about 4.86 x 10^-19 joules for visible light, you can divide the total energy emitted per second by the energy of each photon to find the number of photons emitted.
What do light sensors measures?
Light sensors measure the number of photons or the energy of light hitting the sensor.
