are light affected by gravity?

Yes, light is affected by gravity but not directly. Gravity affects objects which have some mass but light particles do not have any mass so gravity cannot affect it directly. But it affects the space-time continuum in which light travels. ... Light has a fixed speed which doesn't change.

All of the light from the Sun and other sources consists of photons which are the electromagnetic force carriers. Magnets and the Earth's magnetic field, which protects us from harmful radiation, are aspects of the electromagnetic force.

Light travels so fast that light emitted from the Sun travels 150 million km to Earth in only about eight and a half minutes. However, when light travels in matter, it interacts with the atoms and molecules in the material and slows down. As a result, light travels fastest in empty space, and travels slowest in solids.

Yes, they are affected by gravity. ... One problem is that electrons have a tiny mass and the gravitational force is much much weaker than the Coulomb force, making it difficult to observe it.

Light is a form of energy, not matter. Matter is made up of atoms. Light is actually electromagnetic radiation. Moving electric charge or moving electrons (electric current) cause a magnetic field, and a changing magnetic field creates an electric current or electric field.

Ocular light sensitivity can not only lead to pain via sunlight, but it also can lead to other physical changes like: skin or muscle changes around the eye, lesions, visual floaters, dry eyes, inflammation, and retinal dysfunction. And ALL of these can cause further discomfort when in the presence of outside lighting.

Gravity causes every object to pull every other object toward it. Some people think that there is no gravity in space. In fact, a small amount of gravity can be found everywhere in space. Gravity is what holds the moon in orbit around Earth.

So, the gravitational force is super tiny. The only way we ever notice this force is if one of the interacting objects has a super huge mass—something like the mass of the Earth (5.97 x 1024 kg). ... The short answer is "yes"—there is gravity in space.

Light is composed of photons, so we could ask if the photon has mass. The answer is then definitely "no": the photon is a massless particle. According to theory it has energy and momentum but no mass, and this is confirmed by experiment to within strict limits.

Photons, whether they are particles or waves seem not to interact with this field at all acording to their speed, however they are still affected by gravity. ... gives some particles rest mass. The other particles, lacking rest mass, still have inertial mass, which is identical to gravitational mass.

The wavelength and frequency of light are inversely proportional to each other. Ex) wave length of light increases= the frequency decreases. ... The light emitted by an electron moving from a higher to a lower energy level has a frequency directly proportional to the energy change in the electron.

You can see light from the moon, distant stars, and galaxies because light is an electromagnetic wave. Electromagnetic waves are waves that can travel through matter or through empty space. ... As a result, light travels fastest in empty space, and travels slowest in solids.

A prism deflects or shifts light but has no ability to focus light. Yet, the yoked prisms can change the phase or timing of light. Through this change in phase it can influence the communication between the visual, auditory, vestibular and proprioceptive sensory systems in the brain stem.

As the size of a star increases, luminosity increases. If you think about it, a larger star has more surface area. That increased surface area allows more light and energy to be given off. Temperature also affects a star's luminosity.

The simple answer is that it depends on the medium it travels through. specifically it is determined by the permittivity (epsilon) and magnetic permeability (mu) at the wavelength of the photon.

As a curvature, or warping of spacetime, gravity is neither a push nor a pull. Astronauts in orbit float freely, i.e., force-free, under the influence of gravity, even though they seem to be pulled in an accelerated path around the earth.

The variation in apparent gravitational acceleration (g) at different locations on Earth is caused by two things (as you implied). ... The distance between the centers of mass of two objects affects the gravitational force between them, so the force of gravity on an object is smaller at the equator compared to the poles.
