What else can I help you with?
Can two cars of different mass have the same kinetic energy?
Yes, two cars of different mass can have the same kinetic energy if they are moving at the same speed. Kinetic energy is dependent on both mass and speed, so if the speeds are equal, the kinetic energy will be the same regardless of the mass.
Is photon energy the same for all wavelengths of light?
No, photon energy is not the same for all wavelengths of light. The energy of a photon is directly proportional to its frequency, so different wavelengths of light can have different photon energies. Shorter wavelengths of light have higher energy photons, while longer wavelengths have lower energy photons.
Could you emit the same amount of light energy per second which must emit more photons per second a source of red light or a source of blue light?
A source of blue light would need to emit more photons per second to produce the same amount of energy as a source of red light. This is because blue light has higher energy photons, so fewer photons are needed to achieve the same total energy output as red light, which has lower energy photons.
Can two moving cars of different mass have the same kinetic energy?
Yes, two moving cars of different mass can have the same kinetic energy if they are moving at the same speed. Kinetic energy depends on both mass and velocity, so as long as the cars are moving with the same speed, their kinetic energies will be equal regardless of their masses.
Can two objects have the same temperature but different amounts of mass?
Yes, two objects can have the same temperature but different amounts of mass. Temperature is a measure of the average kinetic energy of particles in an object, while mass is the amount of matter in an object. So, it is possible for objects with different masses to have the same kinetic energy and therefore the same temperature.
What is the difference between a homogenous and a heterogenous beam?
A homogenous beam contains photons of the same energy (monoenergetic)Because the photons all have the same energy, their interactions with materials (such as the absorber) are all the same resulting in uniform attenuation.Heterogenous beams contain photons of different energies.Because the photons have different energies, their interactions with materials (such as the absorber) are different resulting in non-uniform attenuation.
Can two cars of different mass have the same kinetic energy?
Yes, two cars of different mass can have the same kinetic energy if they are moving at the same speed. Kinetic energy is dependent on both mass and speed, so if the speeds are equal, the kinetic energy will be the same regardless of the mass.
What happens when photons collide?
when two photons collide:- 1.a new photon gets formed 2.its direction will be different from that of the two photons. 3.the energy of the photon will remain the same
Is photon energy the same for all wavelengths of light?
No, photon energy is not the same for all wavelengths of light. The energy of a photon is directly proportional to its frequency, so different wavelengths of light can have different photon energies. Shorter wavelengths of light have higher energy photons, while longer wavelengths have lower energy photons.
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]
Is that true that the more energy of a photon the bigger the mass it possesses?
No, all photons have the same mass. Photons are massless (i.e. zero). All the energy in a photon is in its momentum, but increasing its momentum does not change it speed which is always "the speed of light". All massless particles always move at the speed of light.
Could you emit the same amount of light energy per second which must emit more photons per second a source of red light or a source of blue light?
A source of blue light would need to emit more photons per second to produce the same amount of energy as a source of red light. This is because blue light has higher energy photons, so fewer photons are needed to achieve the same total energy output as red light, which has lower energy photons.
Can two moving cars of different mass have the same kinetic energy?
Yes, two moving cars of different mass can have the same kinetic energy if they are moving at the same speed. Kinetic energy depends on both mass and velocity, so as long as the cars are moving with the same speed, their kinetic energies will be equal regardless of their masses.
Two objects may have the same temperature but they will not have the same amounts of thermal energy unless they also have the same amount of?
mass. The thermal energy of an object is directly proportional to its mass, so objects with different masses will have different amounts of thermal energy even if their temperatures are the same.
How does the energy of three photons of blue light compare with that of one photon of blue light from the same source?
If the color (frequency, wavelength) of each is the same, then each photon carries the same amount of energy. Three of them carry three times the energy that one of them carries.
Can two objects have the same temperature but different amounts of mass?
Yes, two objects can have the same temperature but different amounts of mass. Temperature is a measure of the average kinetic energy of particles in an object, while mass is the amount of matter in an object. So, it is possible for objects with different masses to have the same kinetic energy and therefore the same temperature.
If two different masses have the same kinetic energy their momenta is?
... different. Kinetic energy is proportional to the square of the speed, wherease momentum is proportional to the speed.
