Visible Light Spectrum

Most likely not.

Light is made up of photons, and even photons have mass..Thus light is a particle as particles are mass.

But to confuse you, even though light = photons & photons = particle & particle = mass; the photons also act as a wave.

Which is rather incredible, because it means that a mass also acts as a wave.

Yes. It is marketed under the generic product description "flat black".

Note: You may from time to time encounter an advertisement promoting "fat back",

particularly in close proximity to ethnic restaurants. Do not be misled, for that is an

entirely different product.

No, ultraviolet light has a shorter wavelength than visible light. Visible light falls within the electromagnetic spectrum with wavelengths ranging from approximately 400 to 700 nanometers, while ultraviolet light has shorter wavelengths below 400 nanometers.

Refracting telescopes and reflecting telescopes are commonly used to observe stars in visible light. These telescopes utilize lenses or mirrors to gather and focus light, allowing astronomers to view stars with clarity and detail.

Visible light is found in the electromagnetic spectrum between infrared and ultraviolet light, with wavelengths ranging from about 400 to 700 nanometers. It is the range of electromagnetic radiation that is visible to the human eye.

The constellation Lacerta is typically visible in the northern hemisphere during the months of September through December. It can be best seen in the evening sky during these months.

1. Ultraviolet radiation: has shorter wavelengths than visible light.
2. X-rays: have even shorter wavelengths than ultraviolet radiation.
3. Gamma rays: have the shortest wavelengths and highest energy among electromagnetic radiation.

Radio waves have the lowest frequency in all of the electromagnetic spectrum. The next higher frequency energy is microwave, visible light including ultraviolet, infrared, X-ray, then gamma ray

On the visible spectrum, blue is the hottest color. This is because blue light has a higher energy level than other colors in the visible spectrum, such as red or yellow. Hot objects, like stars, emit more of their energy in the blue end of the spectrum.

A ripple tank creates waves by vibrating a surface with a motor underneath the tank. This makes the surface of the water move up and down, creating the waves that are more visible due to the light shining from above, which reflects off the waves and reveals their patterns and behaviors.

infrared, red, orange, yellow, green, blue, purple, ultraviolet. The sun has a lot of different colors in it, all you have to do is take a prism, and put it in front of a beam of sunlight, to see that the white light coming from the sun has many parts.

Just realize humans cannot see infrared or ultraviolet.

Red light has the longest wavelength in the visible spectrum.

Infrared light, microwaves and radio waves have wavelengths longer than visible light. Radio waves have the longest wavelength.

Visible light has a lower frequency than infrared radiation. Visible light ranges in frequency from approximately 430 THz (red light) to 750 THz (violet light), while infrared radiation has frequencies below 430 THz.

Nikola Tesla used a high-frequency electromagnetic field to transmit electricity wirelessly, known as Tesla coils. When he held a light bulb near the coil, the electromagnetic field induced a current in the bulb, causing it to light up without the need for direct electrical connections.

If you are referring to fluorescent and CFL lamps, it can never be totally eliminated. These are mercury vapor arc lamps using a phosphor to turn the UV to visible light. They have reduced the mercury dramatically, but it can't be totally eliminated.

If all fluorescent and CFL lamps were banned and lighting was all converted to LED then use of mercury could be stopped. However most LED lamps cost at least ten times what CFL lamps cost.

Some electromagnetic waves are invisible and some aren't. Light is electromagnetic radiation, and we can see it. Radio waves aren't, and neither are x-rays or cosmic rays. All of these are electromagnetic waves.

Light can do many things. some of the thing are that light can give things color, can make solar calculators work, can make cars move, and also it can help plants grow. That's ome of the things light can do.

The EM spectrum ranges from very long radio waves at around 1000m or longer, to gamma rays at around 0.01 nanometers (nm). The visible part of the spectrum (for human eyes) ranges from 700 nm (red) to 400 nm (violet). One nanometer = 10-9 meter.

You may sometimes find reference to Angstroms, which used to be used for this range before SI was fully established. One Angstrom is 10-10 of a meter, ie 0.1 nm, so the range of visible light would be 7000 to 4000 Angstroms.

There is a nice diagram showing the visible range in the total spectrum, at Wikipedia

A fluorescent light bulb converts ultraviolet waves into visible light using a phosphor coating inside the bulb. When the UV light hits the phosphor coating, it emits visible light.

Minerals that emit visible light when exposed to X-rays include some types of diamonds, certain sulfides like willemite and sphalerite, and various fluorides such as fluorite. This phenomenon is called X-ray luminescence or X-ray-induced luminescence and is used in mineral identification and fluorescence studies.
