Are photons be emitted from all source of light?

Question

Source of light may be sun, moon, electric bulb, fire, etc

Answer 1

photons ARE light.

if an object is emitting light, then by definition, it is emitting photons.

BUT all EM radiation exists in photons. so if by light, you mean just visible light, then dont forget that EM radiation outside of the 400-700 nm (visible) range will also be photons.

right, and the moon is generally not emitting photons, but it is relecting some of the photons from the sun that hit it.

Answer 2

A source of light is not the source of photons!
It is the change of state of an electron around its nucleus (loosing energy and moving to a lower orbit) that generates a quanta of energy, a PHOTON. The frequency of the vibration of the photon (depending on its energy) determine if the photon witll be in the visible wavelength range.
So, a source of lights emits photons because its atoms are loosing energy.

Answer 3

Since light is made up of photons, then yes. But remember the moon is not a source of light, it is only reflecting photons from the sun.

Answer 4

it is the right mass (aka relax mass), m_0 of a photon it really is 0, no longer it is inertial mass (aka relativistic mass). The inertial mass of a particle equals the price of the debris momentum divided with suggestions from its %, i.e. m = p/v and considering that for a photon v = c we've m = %. also for a photon E = computing gadget we get p = E/c so as that m = (E/c)/c = E/c^2. For a photon E = hf the position f is the photon's frequency and h is Planck's consistent. We hence get m = hf/c^2. you'll discover all of this in maximum particular relativity textbooks, even present day ones, consisting of particular Relativity, A. P. French, MIT Press, web page 20.

Answer 5

light is made up of packets of energy called photons.they are emitted from sources of light like ultra violet light,microwave light,radio waves etc when they hit a metal.photons do not have mass.that's why light is not weighed down when it travels in a straight line.photons have only energy value.these photons when emitted can be used for many electric purposes.it is called photoelectric current.used in burglar alarms,automatic on and off of switches,opening and closing of doors automatically etc

Answer 6

From 'Newtons' theory light emmits a wave with diffrent size & shape But from hygins wave theory light emmits a photon
2- All source of light emitted photon with energy hm' h-planks constant m'-mobiliti of electrons

Answer 7

A photon is a "light particle". It is the essence of electromagnetism. The photons ARE the source of light.

Answer 8

All objects emit photons or light, be it sun, moon, earth, table, chair, etc.

Answer 9

Light = Photons
wherever there is light there will be photons.

Answer 10

Yeah DL is right.....
