What else can I help you with?
Does light have weight?
If light is made of photons and photons have mass then you would assume that light has weight in a gravitational field. In fact light running into an object imparts momentum to it. However photons have no rest mass. If they did , objects that were exposed to sunlight and absorbed it would get heavier as time goes on, they don't. So light has no mass and hence no weight.
Why are photons not like ordinary particles of matter?
Photons are massless particles that do not experience gravitational forces, unlike ordinary particles of matter. They also do not have rest mass and always travel at the speed of light in a vacuum. Additionally, photons do not have electric charge, which distinguishes them from most ordinary particles of matter.
How are photons affected by gravity?
Photons are affected by gravity because they have energy and momentum, which can be influenced by gravitational fields. Gravity can cause photons to change direction or lose energy as they travel through space. This effect is known as gravitational lensing.
What has no mass?
Not many things have no mass however Photons (Light Particles) have no mass and therefore they travel at the speed of light.
The mass of an object in a gravitional field is called?
The mass of an object in a gravitational field is called the object's "mass".The presence or absence of a gravitational field has no effect on the mass.

Is light particulate matter?
Light is made up of particles called photons, which are packets of energy. These photons have no mass but they do have momentum and behave both as particles and waves. So in a sense, light can be considered a form of particulate matter.
What is the mass of all photons from the sun striking the Earth in a year?
Mass of photons? Zero, photons have no mass. If you mean energy, that is a different question, ask it.
mass of photon?
Photons have no mass.

How does an object's inertia cause it to behave?
its mass helps it behave
Is light a example of matter?
Light is considered to be energy, but it is carried by photons, which we know have some mass because a strong gravitational force can change the direction of light.

Do photons have physical mass?
Photons have mass.Photons have momentum.Photons have energy.Photons are affected by a gravitation field and follow a curved path called a geodesic. (A geodesic is a straight line in curved space, so what you call curved depends on whether you are a geometer or if you are watching from a distance.)Photons have a gravitational field of their own which exerts an attractive force on other matter.Photons interact electromagnetically with matter and other photons.Energy of a photon equals Plank's constant times the frequency.Mass of a photon is equal to energy divided by the speed of light squared.Higher frequency photons have more energy and hence more mass and it is well known that sometimes the energy of a photon can be converted into a particle with mass (usually in pairs).Photons have zero "rest mass" but that is not the "mass" in E=mc2. It is not rest mass that determines momentum or energy or gravitational attraction.And, photons are never at rest.If you accelerate to "catch up" to a photon, the photon does not appear to slow down, but its frequency decreases and energy decreases, approaching zero (same as the "rest mass" as you approach the speed of light.All that is true, but it is also true that characterizing any of these in a proper theoretical framework will inherently involve quantum mechanics, special relativity and general relativity.Addendum:If the question is posed as to whether photons have "physical mass," one must ask for a definition of nonphysical mass. There is mass, just mass, and there is no circumventing "mass." It does not come in types or flavors or with provisos. Mass is mass. One more thing for the questioner:Photons are quanta of energy, photons are not matter. They have mass since energy has mass. Mass as a property of energy is no different than mass as a property of matter. [Great summary of photon properties above]
Can electromagnetic waves can behave like what type of particles?
Electromagnetic waves can behave like particles known as photons. Photons are the quanta of light and exhibit both particle-like and wave-like properties.
