How does gravity interact with photons?

Gravity is the distortion of the shape of the lemon. Photons may not have any rest mass, but they move in a straight line. When there’s gravity, straight lines are not straight anymore, and therefore photons curve around massive bodies.

Do photons react to gravity?

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.

Do photons interact with other particles?

Since light itself does not have electric charge, one photon cannot directly interact with another photon. Instead, they just pass right through each other without being affected. In this process, the energy of the photon is completely transformed into the mass of the two particles.

How does the gravity of an object affect light?

According to Newtonian gravity, light is not affected by gravity, as light is massless. Einstein’s law E = mc2, immediately suggests that light is affected by gravity. This is indeed the case and has experimentally be observed via gravitational lensing and other effects.

Does gravity affect electricity?

Gravity is a four billion times weaker than the electromagnetic force that drives electrons in circuits, and so has absolutely no effect on electricity.

How do photons interact with matter?

Photons interact differently in matter than charged particles because photons have no electrical charge. give up their energy via secondary interactions (mostly ionization). The interaction of photons with matter is probabilistic, while the interaction of charged particles is certain.

How does gravity affect light and time?

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 .
