- Q: how does the eye recieve light?
- Light enters the eye passing through the cornea (the clear front part of the eye) and lens and then hits this retina. The retina contains cells called photoreceptors. Within the photoreceptors are molecules (rhodopsin) that change their conformation when stimulated by light. This change triggers an electrical impulse which is sent to the brain.
- Q: What makes light so fast ,and can nothing attain this speed except light itself?
- Light is so fast because it has no rest mass. Light can be stopped by both a partical and a wave, not sure how exactly but it can be stopped.
- Q: Hey all,I would like to know what are the 2 classification of aircraft lights. The 1st one is Navigation Lights and Beacons. what is the other one?
- I've never heard anything about specific classifications of lights, but there are nav lights, anti-collision (beacon and strobes), landing/taxi lights, recognition lights, and a slew of other lights used primarily on larger commercial aircraft.
- Q: the light light that we can see not the heat or energy
- LEDs and lasers produce monochromatic light without an infrared component. For that matter, fluorsecent tubes don't put out much IR either. So they won't wam you up like the sun or an incandescent bulb will, but the light is still converted to heat when it is absorbed. Using LED lights in a hot climate like an operating room in the tropics does reduce the heat load considerably, without using air conditioning. Light is energy, so you can't have light with no energy.
- Q: I know the speed of light is 186,00 mph (or something like that) but what exactly is a light year?
- A light year is the distance light travels in one year. Or, for sci-fi, the distance you go in one year if you travel at the speed of light. Light-years are a measure of distance, not time. So if your stars are ten light-years apart, it takes ten years at the speed of light to travel from one to the other.
- Q: Explain the propagation of light. and a brief summary of particle and wave theories of light. No, it's not my homework.
- all phenomena with regards to mild, the place its wave nature is skipped over are a consequence of rectilinear propagation of light. a number of those effects are ---- formation of lunar and image voltaic eclipses, dispersion of light in a prism, working of a digicam, working of a pinhole digicam, working of lenses used for correction of ingenious and prescient, working of microscope, working of telescope, working of periscope, image formation by using around mirrors and lenses, and formation of mirages , looming and so on.,
- Q: what is faster thin light and what Color is light
- In a vacuum, nothing is faster than light. In other media, small particles, such as neutrinos, can be faster than the light in that medium, giving rise to what is known as ?erenkov radiation. Light has no inherent colour. All electromagnetic waves move with the same speed. This includes radio waves and gamma rays, which we are unable to see.
- Q: is light from a light bulb polarized? Is light reflected from a plane mirror polarized? What about light reflected from a glass plate or shiny laboratory surface?
- Light has to be filtered to be polarized. Some sunglasses are polarized. They have tiny slits that let only light which wavelengths travel with its axis parallel with the slits in the fliter. If you take two polarizing filters with slits 90 to each other this blocks almost all the light. to answer your question. None of the above light is polarized unless it has passed through a polarizing filter
- Q: If you need light to see into a mirror can you see yourself with nightvision goggles?
- No. Because nightvision gear provides your eyes with light from another light spectrum we can't normally see otherwise your eyes would have light and you could see yourself in a mirror.
- Q: Do they need uva/uvb lights?
- They do not need light but it is good to have the lights on in the room that they are kept in for at least 10-12 hours a day, especially when being fed. But no they don't need a special light just have something on them for a couple hours.
