    Photons
In summary, when lights are turned off in a cave, the photons that were previously visible are absorbed into the mass of the cave. The ones that bounce off the rocks are the ones we see. The absorption of photons depends on the color or absorption spectrum of the material. When a photon hits matter, it can be absorbed by an electron, an up quark, or a down quark, causing the electron to jump to a higher energy state. This energy is eventually converted into thermal energy of the atoms on the wall.

I was in a cave and they turned all lights off. First time I experienced total darkness. When they turned lights out, where do the photons go?

Welcome to PhysicsForums!

Generally, they will be absorbed as heat.

OK so the photons are absorbed into the mass of the cave. The photons are flying around, the ones that have a wavelength in the visible range, I can see. So the phtons that bounce off the rocks are the ones i see?

What determines which one get absorbed, and which ones get reflected? Well I guess utimately they all get absorbed? Some just get reflected a few times before getting absorbed?

As the photon approaches the matter- it hits either an electron, an up quark, or down quark. Will you explain what happens next? what do you mean by "absorbed"?

Yes!

A simple answer would be that the ones get absorbed or reflected depends on the color of the material. A more precise answer would be that it depends on the absorption spectrum of the material, which is a detailed list of the probability of absorption for each wavelength.

The photon dissapears and its energy makes an electron to jump to a higher energy orbital. This energy is eventually all converted into kinetic energy of the atoms on the wall (thermal energy).
 

FAQ: Cave of the Winds, CO - photons

What are photons?

Photons are tiny particles of light that have both wave-like and particle-like properties. They are the basic unit of electromagnetic radiation and they carry energy.

How are photons related to the Cave of the Winds in Colorado?

The Cave of the Winds in Colorado is a popular tourist attraction that features underground caves with natural formations and intricate rock structures. These structures are illuminated by photons from natural light sources or artificial light sources, allowing visitors to see and appreciate the beauty of the caves.

How do photons travel through the Cave of the Winds?

Photons travel through the Cave of the Winds in straight lines until they hit an object or surface. When they hit a surface, they can be reflected, absorbed, or transmitted, which determines how light behaves in the caves and how much of it is visible to the human eye.

Can photons be seen in the Cave of the Winds?

Photons themselves cannot be seen because they do not have mass or color. However, the effects of photons can be seen in the form of light and color in the Cave of the Winds. These photons are what make the cave visible and create the beautiful colors and patterns on the walls and formations.

How do photons contribute to the ecosystem in the Cave of the Winds?

Photons play an important role in the ecosystem of the Cave of the Winds. They provide the necessary light for photosynthesis to occur, allowing plants and algae to grow and provide energy for other organisms. They also serve as a source of heat and energy for animals that live in the cave.
