What are facts about ultraviolet waves waves?
Ultraviolet (UV) waves have shorter wavelengths and higher frequencies than visible light waves. They are not visible to the human eye but can cause sunburn and skin damage. UV waves are also used in sterilization, fluorescence, and to detect counterfeit money.
What is the relationship between the frequency of light and its color?
The frequency of light determines its color. Light with higher frequency appears blue or violet, while light with lower frequency appears red or orange. This relationship is described by the electromagnetic spectrum, where different frequencies correspond to different colors.
Why are UV lights purple?
UV lights appear purple because they emit ultraviolet (UV) radiation, which is not visible to the human eye. However, some UV lights are designed with a special coating that converts the UV radiation into visible purple light, allowing us to see the light emitted by the UV source.
The primary colors of visible lights are?
The primary colors of visible light are red, green, and blue. These colors can be combined in various ways to create all the other colors in the visible spectrum.
Do black lights exist and how do they work?
Yes, black lights exist. They emit ultraviolet (UV) light, which is not visible to the human eye. When UV light hits certain materials, they absorb the light and then re-emit it in a visible spectrum, creating a glowing effect that we can see. This is how black lights make objects appear to glow in the dark.
Do radio waves microwaves and ultraviolet waves all have longer wavelengths than visible lights?
Radio and microwaves are longer than visible light. So are heat (infrared) waves. Ultraviolet waves are shorter than visible light. So are X-rays and gamma rays.
What has lights?
Microwaves

What is Ultraviolet lights?
Ultraviolet light (UV light) is light of shorter wavelength than the visible spectrum. Many insects, like bees, see mostly UV light so they can find plants with nectar. Sunlight contains UV light and can tan but also damage your skin if you stay outside too long on a sunny day.Answer:Visible light is electromagnet radiation of different frequencies. The different frequencies are the different colors. Just outside the range of frequencies (colors) humans can see are infrared and ultraviolet. Ultraviolet is higher frequency and infrared is lower.Note: Higher frequencies are shorter wavelengths and lower frequencies are longer wavelengths.Visible light is electromagnet radiation of different frequencies. The different frequencies are the different colors. Just outside the range of frequencies (colors) humans can see are infrared and ultraviolet. Ultraviolet is higher and infrared is lower
Why aren't black lights black?
Black as a color would absorb all visible frequencies of light. A "black light" is not actually black, but rather emits most of its light in the ultraviolet frequencies. This light is invisible to our eyes except that it interacts with certain materials that fluoresce (glow in the dark) when they absorb UV light. These lights are also used for indoor plants that need UV light to grow.
How do wavelengths of visible lights relate to energy?
The shorter the wavelength (blue rather than red), the higher the energy.
Why use microwaves instead of visible light?
-- We have no technology that can generate visible light at power levels that are easy to generate in the microwave. -- Visible light won't warm up a leftover chunk of meatloaf. -- For telecom applications, microwaves sail right on through atmospheric conditions that scatter, diffuse, and absorb visible light. But your question doesn't mention what uses you're thinking of, and visible light certainly has its place. For example, microwave traffic lights at intersections would not work out too well. Neither would a microwave chandelier hanging over your dining-room table.
What happens to cosmic microwaves when they meet big water droplets in the air?
you get the northern lights
Why are the northern lights mostly visible at the poles?
The northern lights, also known as auroras, are more visible at the poles because Earth's magnetic field directs charged particles from the Sun towards the poles, where they interact with the atmosphere to produce the colorful light displays. Areas closer to the poles have a higher concentration of these charged particles, making the auroras more frequent and visible.
Can you see the northern lights in Texas?
It is very rare to see the northern lights in Texas due to its location being too far south. The northern lights, or aurora borealis, are typically visible in higher latitude regions closer to the North Pole.
Are the Northern Lights visible in Russia?
yes
What lights are similar to fluorescent lights except that the electron and gas collisions give off visible light?
Neon lights.
