Are rainbows part of visible radiation?
A rainbow shows the optical (visible) part of the electromagnetic spectrum; infrared (if you could see it) would be located just beyond the red side of the rainbow with ultraviolet appearing just beyond the violet end. The way to rembember the colors of the rainbow are Roy G Biv, meaning Red, orange, yellow, green, blue, indigo, and violet.
How do you use optical in a sentence for kids?
A mirage is a common optical illusion.
What is an easy definition of the optical axis?
An optical axis is a line along which there is some degree of rotational symmetry in an optical system such as a camera lens or microscope..
What two optical devices use convex lenses to focus and enlarge images?
An optical microscope or twlescope.
Do optical illusions do anything to your eyes?
No optical illusions can not hurt your eyes they just make you feel like it
What kind of electromagnetic waves from the sun bring heat energy to trees?
Electromagnetic radiation in Optical and Infrared frequency.
What does a specialized non-optical telescope see?
There are telescopes used to detect radio waves and others to detect infrared radiation.
What type of electromagnetic wave has highest energy a ultraviolet wave or an infrared wave?
Infrared radiation has a lower frequency than optical light as it is below the red end of the spectrum. "Infra" means below, making "infrared" meaning "below red. On the other hand, ultraviolet radiation has a higher frequency than optical light as it is above the violet end of the spectrum. "Ultra" means "above or greater", making ultraviolet meaning "above violet". The answer to your question would be: ultraviolet radiation has more electromagnetic energy than infrared radiation.
Optical telescopes are designed to collect and create images from is it white or visible light or x rays or infrared radiation or gamma rays?
An "optical" telescope would naturally collect light from optical wavelengths, meaning visible light from ~400-800nm.
Does Heat have shorter wavelengths than visible light?
No. Heat is infrared radiation ("infra" means "lower"). Lower frequency means longer wavelength. All radiation is captured by antennas that resonate at the frequency of the radiation. The "antennas" for visible light are electrons that use the radiation to jump into excited states and cause optical neurons to fire. The "antennas" of heat (infrared) are bigger -- they are molecules that jiggle faster when the radiation hits them. That jiggling is heat.
What has the author Kenneth Borg written?
Kenneth Borg has written: 'Computations on interstellar extinction' -- subject(s): Interstellar matter, Optical properties
Why is a cell phone an optical technology?
Because they work primarily using electromagnetic waves - which encompass radio waves, visible light, microwaves, UV radiation, lasers, gamma rays, infrared rays, and X-rays... all of these are optical technologies.
What has the shorter wavelength ultraviolet or infrared?
The infrared (IR) radiation has a longer wavelength (and a lower frequency) than ultraviolet (UV) radiation. The former is below the visible spectrum, and the latter is above that visible (sometimes called optical) spectrum. However, IR radiation does not have the longest wavelength in the Electromagnetic Spectrum. That would be the Radio Waves. Additionally,: The prefix Infra- suggests "standing under, sub-, inferior to" (IR: Standing under Red light waves) The prefix Ultra- suggests "standing beyond" Violet light waves
What can you see with a non-optical telescope?
An optical telescope is one that is desigend to see light. Other telescopes will observe some other radiation, usually some kind of electromagnetic radiation. This can include anything in the EM spectrum: radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays. Watching the Universe in these radiations makes it possible to see some things that are not visible in normal light. For example, far-away objects in our Solar System will not reflect a significant amount of light, but can be visible in infrared.
What is radiant heating?
In general, radiant heat is heat energy that is transferred through electromagnetic radiation in the form of light. We usually refer to it as thermal radiation. Much of the heat that is radiated this way is propagated in the form of infrared radiation, which is light just below the optical spectrum.
What type of energy travels as visible radiation?
Optical Light is visible radiation energy.
Which type of pointing device has crisscrossed invisible beams of infrared light that are?
optical mouse
