No. Light is light.
A:
It's the wavelength that photodiodes are sensitive too. Specs vary widely, so photo emmitters have to be matched with photodiodes, or they won't 'see the light' This comes in handy when using your IR remote on a fairly bright day. If your TV could see all light, it would be blinded.
Red, green, and blue light. Rods are only sensitive to black and white.
yes. laser beams are just like light.
The word laser means light. This means that while having any type of laser eye surgery dose not increase or decrease in temperature. This is because only white light can increase its temp.
photosensitive receptor.cones and rods.cones work in bright light and are sensitive to colours whereas rods work in dim light and are not sensitive to colours
i think its the retina
Since Laser is light and light is faster than anything we know of on earth the laser is faster, especially if it is a constant beam. Bullets can travel faster than sound, but still nowhere near the speed of light. Besides, despite what you see in Star Wars, there are not laser guns, only lasers.
That's monochromatic, coherent light. A well known source of such light is a laser.
The reason we can only see lasers through dust or cloudy water is because our eye can only see light that enters directly into them. When a laser travels across our plane of vision the laser beam is traveling in a straight line, but when it hits the small particles of dust that light is being reflected in an infinite number of directions. A portion of those reflected light rays enter our eyes resulting in what appears to be a laser beam.
No. A laser is a bean of light that propagates in one direction with little spread and generate light only over a very small range of wavelengths. The rays of sunlight are parallel only because of our great distance from the sun. Sunlight can be focused to a point using mirrors or lenses, but will spread out beyond that point, rather than as a coherent beam light a laser. Additionally, sunlight consists of the entire spectrum of light.
Continuous I assume would mean a constant flow of light from the laser in the form of a wave train. Conversely, a pulse is only a single wave emitted by the laser.
It is formed of electromagnetic radiation - light, with only one wavelength, (one colour); highly directional and focused, that is, the rays of the light of a laser don't disperse much; and all the waves are moving in sinchrony, in phase.
The color of a beam of light is dependent on its wavelength. A laser will appear as one color because all the light being emitted from it is the same wavelength. This is also why lasers and laser pointers always have such a tight beam. By contrast, flashlights (which have much wider beams, and rely on mirrored interiors to amplify the light) have light at a variety of wavelengths, which is why the light is ultimately "colorless".
