Photons have no invariant mass (the hypothetical mass they would have if they weren't moving, which cannot happen). So in that sense, light is massless.
However, light (and individual photons) have energy, and we know from Einstein's famous formula that energy is related to mass. (A different formula E=hv relates energy to frequency, so we can even calculate the precise equivalent mass for any given wavelength of light). In this sense, light has mass, and this can be shown by gravitational lensing, where a large enough concentration of mass can actually bend the path of light ... precisely as would be expected if light had mass.

Does a photon have electrons?
No. A photon is a particle of light. It is massless.
What are massless particles traveling the speed of light?
Massless particles traveling at the speed of light include photons, the particles of light. They have no rest mass and always move at the speed of light in a vacuum according to the theory of special relativity.
What are some examples of mass in science?
Light, heat, energy, emotions. All are massless.
When a beam of light is falling on prism surface and bend then which force is apply on its corner?
The trick behind this is that light is photons, which are massless.
Does light have mass?
No, light does not have mass. It is composed of particles called photons, which are massless and travel at the speed of light in a vacuum.
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.
Is light an example of matter?
No, light is not an example of matter. It is an example of electromagnetic waves. However, it is considered that light is composed of photons (massless particles) and it is applied to it some theories of matter.
Optical lever uses a light beam as a pointer to measure small deflectionsExplain the advantage of this?
It is massless and it is not affected by gravity.
Who discovered that light has mass?
Light does not have mass. It was through experiments and theories in physics that it was established that light, being composed of massless particles called photons, does not have mass.
Is electrons light?
No, electrons are subatomic particles with a negative charge. Light, on the other hand, consists of photons which are massless particles that carry energy and electromagnetic force.
What is an example of something that is not matter?
Light is an example of something that is not matter. Light consists of photons, which are massless particles that do not take up space and do not have mass, making them distinct from matter.
According to Einstein light consists of massless bundles of electromagnetic energy called photons True Or False?
True. Einstein's theory of general relativity proposes that light consists of massless particles called photons, which carry electromagnetic energy.
