What causes light to bend in space?

Gravity bends light Light travels through spacetime, which can be warped and curved—so light should dip and curve in the presence of massive objects. This effect is known as gravitational lensing GLOSSARY gravitational lensingThe bending of light caused by gravity .

Is bending of light possible?

Yes, light can bend around corners. In fact, light always bends around corners to some extent. This is a basic property of light and all other waves. The ability of light to bend around corners is also known as “diffraction”.

How does light bend if it has no mass?

Light can form a curve if it travels near a big mass. You are right, photons don’t have mass. You are also right, photons doesn’t follow Newton’s gravitation law. Photons can be pulled by gravity not because of their mass (they have none) but because gravity bends space-time.

Why do photons bend?

When photons travel through the region near a massive object that has caused significant warping, they follow curved paths because the space-time through which they are moving is curved. While it is true that photons have no mass, it is also true that we see light bend around sources with high mass due to gravity.

How can a photon be massless?

Originally Answered: How can a photon be massless? Photon has no rest mass. Rest mass is the mass of a particle that you measure when the particle is at rest in your laboratory. Photons can’t exist at rest in any laboratory, they always have to move with the speed of light, lest they cease to exist.

Does the light or photons have mass if no then how photons have momentum?

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. They also say that a photon has momentum, and momentum p is related to mass m by p = mv.

What is bending light called?

The bending of light as it passes from one medium to another is called refraction. The angle and wavelength at which the light enters a substance and the density of that substance determine how much the light is refracted.

Can you bend light with a magnet?

Although a magnetic field doesn’t affect the photons of light directly, a magnet can distort the medium through which light passes and thereby “bend” the light rays. A strong magnetic field can increase the effect of the mass of the object on the curvature of space-time.

Can photons bend?

Does photon have mass?

Since photons (particles of light) have no mass, they must obey E = pc and therefore get all of their energy from their momentum.

Why do photons have no mass and bend light?

While it is true that photons have no mass, it is also true that we see light bend around sources with high mass due to gravity. This is not because the mass pulls on the photons directly, but instead because the mass warps the space-time through which the photons travel. Imagine a bowling ball on a mattress.

Is the bending of light caused by gravity?

If Newton’s gravitation could define the bending of light by gravity, then the general relativity wouldn’t have come up. Photons don’t have mass and it’s clear from the fact that it travels at the speed of light.

Why do photons bend in a curve?

When we look at photons in space, they seem to bend in a curve through space. Light can form a curve if it travels near a big mass. You are right, photons don’t have mass. You are also right, photons doesn’t follow Newton’s gravitation law.

Do photons in space have mass?

A big mass, such as a black hole, may curve space-time so much that a straight line in space-time isn’t straight anymore. When we look at photons in space, they seem to bend in a curve through space. Light can form a curve if it travels near a big mass. You are right, photons don’t have mass.
