How long is semen visible under black light?
I'm pretty sure any black light would work just fine
How long can you see semen under a black light for?
48.532 hours
How is infrared radiation different from visible radiation?
Both are examples of electromagnetic radiation. Infrared has a longer wavelength (lower frequency) than visible light. Of course visible light is visible to humans and infrared is not (although long wave Infrared is sensible to humans as heat).
Who have longer wavelengths visible light or radio waves?
The longest radio wave used for communication is around 3 millimeters long. The shortest visible wavelength of light is around 0.0004 millimeters long.
What color of visible light has the fastest velocity?
As long as they're all traveling through the same material, all colors of visible light have virtually identical speed.
Can visable light be dangerous to humans?
YES. Visible light is the leading cause of death of humans on the Earth and is extremely dangerous. THIS IS IMPORTANT. If you see visible light in the wild, DO NOT APPROACH IT. I am the administrator of the Organization for Protection Of Humans from the Dangers of Visible Light (OPOHDOVL). Always remember to watch out for visible light in the daytime. That's when they get you!
Where to get uv light bulbs?
UV lamp, also called Black-light Lamp, device for producing electromagnetic radiations in the wavelengths between those of visible light and X-rays. The Sun's rays are rich in such radiation, sometimes referred to as black light because it is not visible to the unaided eye.
A powerboat less than 39.4 feet long is anchored at night From which direction must a white light be visible?
A powerboat less than 39.4 feet long is anchored at night white light must be visible from all directions.
What form of electromagnetic waves falls just after visible light on the electromagnetic spectrum this form will have higher energy and a shorter wavelenght than visible light?
That depends which way you are moving along the electromagnetic spectrum.If you are moving from low to high frequency, then the last category before visible light is infrared radiation.If you are moving from short to long wavelength, then the last category before visible light is ultraviolet radiation.
What type of radiation is reflected away from the earths surface?
Long-wave radiation and visible light.
Does ultraviolet light have long or short wavelengths?
The wavelengths for UV light are shorter than for visible light, but much longer than for x-rays or gamma rays.
Is there a different taste to semen if there has been no ejaculation for a long time?
No here the semen will taste the same.Even after a long time.
