…but I’m gonna ask them, because that’s how I roll. These are some things that rattle around in my head, and remember “there is no such thing as a stupid question”, right? That’s what they always told me!
Ok, so, first up….
Do all photons move at the same speed? Can some photons move at different speeds or are all photons moving at the same speed? What causes them to have speed? What is their mechanism of propulsion? In other words, how do they move and what keeps them going?
edit I should note, please explain in layman’s terms…VEEERY layman’s terms. I’m just a normal person with some odd questions that I’d like to learn about but I’m not a physicist or anything like that.
Questions :
1. Do all photons move at the same speed?
2. Can some photons move at different speeds or are all photons moving at the same speed?
3. What causes them to have speed?
4. What is their mechanism of propulsion? In other words, how do they move and what keeps them going?
5. What creates photons? ( Just more interesting Q )
Please use layman's terms if possible.
Answers :
1. Yes, all photons move at the same speed, which is the speed of light in a vacuum. This speed is approximately 299,792,458 meters per second or about 186,282 miles per second.
2. All photons move at the same speed because the speed of light is a fundamental constant of the universe. According to our current understanding, there is no evidence to suggest that some photons can move at different speeds.
3. Photons have speed because they are particles of light, and light is a form of electromagnetic radiation. The speed of light is determined by the properties of the electromagnetic field and the nature of spacetime itself.
4. Photons move in straight lines unless they are influenced by external factors, such as gravitational fields or interactions with other particles. They don't require any propulsive mechanism to move, as they are massless particles. Once created, they continue to travel indefinitely until they either interact with other particles or are absorbed.
5. Photons are created or emitted when certain types of particles, such as atoms or electrons, undergo specific energy transitions or interactions. These interactions can occur in various ways, such as when an electron in an excited state returns to a lower energy state or when charged particles accelerate. When these events happen, photons are released, carrying energy and information in the form of electromagnetic waves. This emission of photons is the fundamental process behind the creation of light. Here are a few examples:
5.1. Light Bulbs: Light bulbs, whether incandescent or LED, create photons by passing an electric current through a filament or semiconductor material respectively. The energy is converted into light, producing photons that we perceive as illumination.
5.2. Flashlights: Similar to light bulbs, flashlights use electrical energy to create photons by passing current through an incandescent bulb or an LED. The emitted photons allow us to see in low-light environments.
