What are the three different type of cone cells?
Cone cells, or cones, are one of the two types of photoreceptor cells that are in the retina of the eye which are responsible for color vision as well as eye color sensitivity; they function best in relatively bright light, as opposed to rod cells that work better in dim light.
How long is semen visible under black light?
I'm pretty sure any black light would work just fine
Does the color of light affect a plants growth?
yes it does certain colors let in more light energy for the plant
Can any light make a plant grow?
According to what I have researched most light can make a plant grow, it just depends on the wavelength that the light is flowing. Carl Gelenye has done some work with different wave lengths of light for plants growth and found the violet works the best and blue is the worst.
Is the frequency of infrared light higher than visible light?
No. X-Rays have a greater frequency than visible light. In order of increasing frequency(or decreasing wavelength). Radio waves, Microwaves, Infra-red radiation, Visible light, Ultraviolet radiation, X-rays, Gamma rays.
Does an uv wavelength of 395 410 nm work as an black light?
Yes, a "black light" is an ultraviolet light with wavelength of about 395-410 nm.
How does Ultraviolet light work?
UV light is the same as any other kind of light or radiation along the spectrum from radioactive waves to radio waves. The difference between them is their wavelength and fequency. The longer the wavelength, the less the frequency. UV light is high-frequency short-wavelength light, just a bit more high-frequency than the highest-frequency visible light, which is violet. How does light work? Well, even physicists aren't quite sure.
What would make a blacklight poster work?
New batteries would make a black light poster work. Replacing the light might also make a black light poster work. Black light poster could also be broken.
How do you work spectrophotometer?
. A spectrophotometer is a photometer (a device for measuring light intensity) that can measure intensity as a function of the color, or more specifically, the wavelength of light
Will black light paint still work without the light?
no....
At what wavelength value does potassium stop emitting electrons when it is flashed with light?
The work function of potassium is 2.26 eV. Therefore a light wavelength must be at least 2.26 times 1.6 times 10 to the negative 19th power J to remove electrons.
How laser pointers work?
Laser lights have certain characteristics that allow it to seperate from regulare white light. The light is colored because it is organized light. It also contains a specific wavelength which produces the colored light.
Does work function depend on wavelength of incident light?
I don't think the magnitude of the current is. But there is a definite wavelength ofincident light where photo-current suddenly begins ... longer wavelengths produceno photo-current at all, no matter how bright the light is. Einstein was awarded hisfirst Nobel Prize for the explanation of why that happens.
Can the work function depend upon the wavelength of light?
Yes, definitely . For the given metal of particular work function, decrease in wavelength of the incident beam increases the maximum value of kinetic energy with which the photoelectrons are emitted, but the photoelectric current remains the same, stoppage voltage increases.
What are the three different type of cone cells?
Cone cells, or cones, are one of the two types of photoreceptor cells that are in the retina of the eye which are responsible for color vision as well as eye color sensitivity; they function best in relatively bright light, as opposed to rod cells that work better in dim light.
Will light brown hair color work on black hair?
yes
What is white light compose of?
Light, no matter what color, is composed of photons. Each photon has a specific wavelength (color) associated with it. Because of the way our eyes work, at least three different wavelengths are required for us to perceive light as "white".
