Except for light reflection does a satellite eminate any other visible light during night time?
I am not aware of any beacon lights on any satellites. I'm sure the International Space Station has some, for times when the Shuttle is coming in, but what purpose would they serve otherwise? Aircraft have anti-collision lights - to avoid airplanes crashing into each other at night. But satellites generally travel too fast for any visual cues to be useful - and satellites have very limited maneuverability anyway.
What would a Long wavelength visible light?
Long wavelength visible light would appear more towards the red end of the spectrum, closer to infrared light. This type of light is characterized by lower energy and longer wavelengths, making it less energetic but still visible to the human eye.
Shorter wavelengths means higher frequency, and electromagnetic waves with higher energy.
Beyond the blue end of the visible light you have ultraviolet rays; X-rays; and gamma-rays, in that order.
How do things absorb uv rays and reflect them as visible light?
When materials absorb ultraviolet (UV) rays, some of the energy is used to excite electrons in the atoms of the material to higher energy levels. As these electrons return to their ground states, they emit energy in the form of visible light. This phenomenon is known as fluorescence.
What are the Frequency and wavelength of visible light?
Light is measured by its wavelength (in Hertz). Wavelength approaches the separation between two progressive wave peaks or troughs. Frequency is the number of peaks or troughs per unit of time.
What color is visible light sprectrum has the most energy per photon?
A photon's energy is directly proportional to its frequency (inversely proportional to its wavelength).
In any given interval of the spectrum, the highest frequency (shortest wavelength) carries the most energy.
For visible light, that corresponds to the violet end of the 'rainbow'. The last color your eyes can perceive
at that end is the color with the most energy per photon.
Why is most of the solar radiation reaching earths surface in the range of visible light?
It's not! The heat (infrared) energy reaching Earth's surface is many times
more than the energy in the visible range ... the visible is practically negligible
in comparison, and then you have the energy in all the other electromagnetic
bands in addition.
Largest visible light telescope?
The largest visible light telescope is the Gran Telescopio Canarias (GTC) located in the Canary Islands, Spain. It has a primary mirror with a diameter of 10.4 meters, making it one of the largest optical telescopes in the world.
What layer of the eye converts visible light into nerve impulses?
I am pretty sure it is the retina.
The retina not only is used for focusing but also The sides of the ''retina'' are responsible for our peripheral vision. The center area, called the macula, is ''used'' for our fine central vision and color vision. Are you referring to optical nerve impulses?
In order of increasing frequency: (i) radio waves. (ii) microwaves. (iii) infrared. (iv) visible light. (v) ultraviolet. hope this helps =)
This sounds like a homework problem, so I will point you in a direction and let you do the rest of the work.
The effect is due to wave canceling/enhancing interference between light reflecting from near and far sides a thin film of transparent material. Different colors appear in places where the thickness of the film differs.
This is also the same effect as the colors seen looking at a thin oil slick on water. Except the thin film here is oil, not soap bubble solution.
Outside light is called natural light what is inside light called?
It's the same thing as "outside light" and is made of the same particles, its just a different velocity of light
Are red yellow and green the colors beyond violet light?
No, red, yellow, and green are not considered colors beyond violet light. Beyond violet light, there are ultraviolet rays, which are not visible to the human eye. Red, yellow, and green are part of the visible spectrum of light.
The light coming into a building through stained glass windows is coloured because?
the stained glass contains metallic salts that create color when light passes through them. Each metal salt produces a specific color, resulting in the colorful patterns seen in stained glass windows. This phenomenon is due to the selective absorption and transmission of different wavelengths of light by the metallic ions in the glass.
Do blue visible light and red visible light have the same wavelength?
No, blue and red visible light have different wavelengths. if you see the rainbow, blue and red can been seen on separate stripes which means they have different wavelengths.
What is the definition of visible light?
"By virtue of the visible light cast by the headlights mounted on the front of my car,
I was able to see and avoid the deer standing in the road, pausing only to make further
use of the visible light and snap a photograph to capture the look of terror in the eyes of
the hapless beast."
This poetic expression suggests that seeking knowledge can be a deceptive journey, as the pursuit of light (wisdom) may lead one astray before finding true enlightenment in darkness. It implies that one's understanding and insight may deepen through the process of losing sight of previous knowledge or perspectives. The paradoxical nature of the text emphasizes the complexity and unexpected paths of the pursuit of knowledge and self-discovery.
How is visible light and electromagnetic radiation different?
Visible light is a specific portion of the electromagnetic spectrum that humans can see with their eyes. Electromagnetic radiation, on the other hand, refers to all forms of energy that travel as waves at the speed of light, including visible light as well as other forms like radio waves, microwaves, and X-rays.
What is the continuous spectrum of a star?
A continuous spectrum of a star is a broad range of electromagnetic radiation emitted across all wavelengths. It results from the thermal energy of the star's interior, causing atoms to vibrate and emit photons at various energies. Continuous spectra can be used to determine a star's temperature.
What is the area behind the color violet called?
The area behind the color violet in the visible light spectrum is called ultraviolet (UV) light. This region of the spectrum has shorter wavelengths and higher energy levels than visible light. UV light is not visible to the human eye but is present in sunlight and is commonly associated with causes of skin damage and sunburn.
The visible color of electromagnetic radiation that has the shortest wavelength is?
The visible color of electromagnetic radiation with the shortest wavelength is violet. The wavelength of violet light ranges from approximately 380 to 450 nanometers.
The lower the frequency of a sound wave the?
For electromagnetic waves:
Speed(v)=frequency(f)*wavelength(lambda)
OR
wavelength(lambda)=speed(v)/frequency(f)
Therefore, wavelength and frequency have an Inverse relationship this means that assuming speed remains constant if the wavelength increases (gets longer) the frequency will decrease.
What is The ability of certain matter to absorb visible light?
The ability of certain matter to absorb visible light is known as absorption. When light interacts with a material, some wavelengths are absorbed by the material while others are reflected or transmitted. Each material has a unique absorption spectrum, which determines which wavelengths of light it can absorb.
Why the Sun emits most of its energy in the form of visible light?
It doesn't. Visible light is only a tiny part of the energy spectrum of the sun's emissions. However the peak point of this very wide distribution occurs in the visible part of the spectrum, which is a consequence of the process of "natural selection" in the development of eyes in living creatures. The peak intensity point is itself determined by the temperature of the surface of the sun. If the sun had been a bit cooler, the peak point would have been in the infra red, and our eyes would be sensitive to that, with curious results.
