Yes, light is also a mass as it contains photon and it behaves both as particle and wave nature which clearly gives states that it has a mass.
Light has nothing to do with mass. Also note that mass is the resistance of a body to a change in motion.
The only thing that travels at the speed of light, is light. Light is also said to have no mass, therefore the only way for something to travel at the speed of light is for it to have no mass.
Neither, mass can never reach the speed of light, this question also contridicts the theory of realativity.
light has zero mass. Photons have zero mass. So according to e=mc2 light must also have zero energy. Astonishing how all these photons reach us from all the way across the universe! But all physical things have mass
Light has mass, because it exerts pressure on a body, e.g. solar sails. light must have mass to exert pressure, because the velocity of what causes pressure? matter. and matter definitely has mass! also, light is attracted to black holes by gravity, so it must have a mass, and the wave/particle duality confirms this
Light 'particles' (photons) have no rest mass.
One of light's defining characteristics is that it does not have mass; it is instead pure energy. To answer your question, no one discovered it because it has been proven to be false.
Not many things have no mass however Photons (Light Particles) have no mass and therefore they travel at the speed of light.
Wrong, Light has mass and does travel at the speed of light and is affected by gravity! Light mass: hf=mc^2 means m=h/cw. Optical mass is m-red=2.96e-36 kg (w=.75um). Violet would be double 5.92e-36 kg. The math for the infinite mass theory at light-speed is also wrong.- -------- Light has no resting mass, just energy. Gravity is a bend in space, therfore Gravity does not pull at light but the light 'bends' with space
No, light does not have mass. Light is composed of particles called photons, which have no rest mass, but they do have momentum and energy.
Light does have mass - since it has energy, it follows that it also has mass. Its REST MASS or INVARIANT MASS, however, is zero. On the other hand, the black hole distorts space and time in its surroundings so much that the only paths a ray of light (or anything moving at the speed of light or less) can take, will take it deeper into the black hole.
Light does not have mass. It is a form of energy.
