Does light have mass and take up space?

Well if you read a textbook, you will find out that light can be thought of as being made up of particles called photons. These photons have no mass! So there is the simple answer, light has no mass and no weight.

Does light carry momentum?

Light does carry momentum. However, light does indeed carry momentum in the form of energy. In fact, for photons (the smallest bits of light), the energy E and momentum p are related by the simple equation E = pc, where c is the speed of light.

Why does mass not change on different planets?

Your mass doesn’t change on other planets, but the gravity and size of those planets affect how much you weigh. So, your weight depends upon the gravity of the planet and your weight keeps changing based on planet gravity. A small planet has less gravity and the larger planet has more gravity.

How does mass affect air resistance of a falling object?

More massive objects will only fall faster if there is an appreciable amount of air resistance present. Thus, the greater force on more massive objects is offset by the inverse influence of greater mass. Subsequently, all objects free fall at the same rate of acceleration, regardless of their mass.

What is the air mass of light?

The Air Mass is the path length which light takes through the atmosphere normalized to the shortest possible path length (that is, when the sun is directly overhead). The Air Mass quantifies the reduction in the power of light as it passes through the atmosphere and is absorbed by air and dust. The Air Mass is defined as: A M = 1 cos θ

Why does light carry energy without mass?

Light indeed carries energy via its momentum despite having no mass. Public Domain Image, source: Christopher S. Baird. Light indeed carries energy and accomplishes this without having any mass. The Einstein equation that you are probably referring to is E= mc2. This equation is actually a special case of the more general equation:

Why can photons move with the speed of light?

Since photons have zero rest mass they can move with the speed of light. MASS OF LIGHT IS NOT 0. Light has mass. Generally,Mass is defined as the amount of substance or matter contained in the body.

How does the general equation work for photons with no mass?

In contrast, for a particle with no mass (m= 0), the general equation reduces down to E= pc. Since photons (particles of light) have no mass, they must obey E= pcand therefore get all of their energy from their momentum. Now there is an interesting additional effect contained in the general equation.
