why dosen't light hit us with a great force as anything that travels at the speed of light, its mass increases

Answer 1

Actually, any massive object has its mass increase the faster it goes, by the time it reaches the speed of light, its mass is supposed to be infinite (which is why a massive object cannot reach the speed of light, it would take all the energy of the universe and then some to get it there).
At the other end, there are photons and their mass at rest is zero. What is zero times infinity? It is an indeterminate. This means the result is actually a function of something else, namely the energy of the photon, which is a function of its wavelength (or conversely its frequency). Since energy is mass times the speed of light squared, energy is mass and vice versa. The result is that light DOES have a pressure, but it is extremely small. Solar sails are envisioned as a way of moving space probes about, but the size needed is extraordinarily large, owing to the very limited "push" light gives. For instance, at high noon, the pressure given by the light from the Sun is, at the surface of the Earth, 4.6 micro Pascal. That is 4.6E-6 Newton per square metre. That is about the weight of a small short hair on 5 square metre (one hair on a surface 7 feet by 7 feet, about a large bed sheet). One hair on a complete sheet is hardly a crushing force, and people simply do not notice that pressure.

Answer 2

Light has no rest mass (m0). It's the rest mass, which is also called inertial mass, that is affected by the speed of light. It is also the rest mass that shows up in F = ma, F = GmM/r^2, KE = 1/2 mv^2, and all those other energy force equations we have come to know and love in physics. So, since m = 0 for light, all these equations come up with a big fat zero for force and energy.

Not to say light has no energy...it does obviously...but its energy does not come from inertial mass in motion. Light's energy comes from the frequency of its vibration...higher frequencies mean higher energies. So a photon of ultraviolet light contains more energy than a photon of infrared light because ultraviolet light has a higher frequency. X-rays are even higher frequency; so they contain a lot of energy that can do some major harm if you are exposed. [See source.]

Good question.

Answer 3

Ok Fırst of all u have got one of ur concepts wrong but that can be easıly solved. Here are 2 fundamnetals whıch wıll help u solve ur doubt -
1. Eınsteın saıd e=mc2 whıch means that ıf the speed of a body ıncreases ıt`s mass gets reduced.
2. There are two types of masses. One ıs assumed mass whıch ıs the one whıch we observe. The other ıs real mass whıch we cannot measure. When a partıcle travels at the speed of lıght ıt`s real mass ıs Assumed Mass/Root of 1-(Velocıty)2/(speed of lıght)2 .As u can see thıs ıs not calculable. Hence ıt ıs not possıble to measure weıght of an object when travellıng wıth the speed of lıght
P.S - Eınsteın saıd that Lıght ıs made of tıny partıcles whıch have no weıght at all
Hope that helps

Answer 4

mild is an electromagnetic radiation outcome of very small messenger debris referred to as 'Photons'. Photons haven't any relax mass although the masslike houses like Momentum. No mass supplies them the no reduce to commute and to be exchanged. Watch the movie lower than for the Standerd kind of 'particle Physics'.

Answer 5

Light does not have a mass. Anything that does have a mass can never reach the speed of light.

Answer 6

photons are massless. they do carry some energy and momentum however, but these are very very small as far as we are concerned.

still, if you have a spaceship, in space, and a large enough piece of ideally reflecting material, the reflection of photons, from the sun, off that surface will progressively accelerate your spaceship to great speeds.

Answer 7

photons do not have mass, otherwise light would obliterate everything.
