If you define the electromagnetic spectrum to begin at 60 KHz ... the radio
frequency used to distribute the signals that synchronize your "atomic" clock ...
and end with gamma rays at 1019 Hz, you've defined a frequency span of
about 47 octaves.
Out of that span, roughly ONE octave is visible to human eyes.
What else can I help you with?
Why astronomers study radiation beyond the violet end of visible light and beyond the red end of visible light?
Astronomers study as much of the spectrum of radiation as they can, and the visible spectrum is only a small segment of it.
How much of the electromagnetic spectrum can your eye detect as light?
The human eye can detect a small portion of the electromagnetic spectrum, known as visible light. This range spans from approximately 400 to 700 nanometers in wavelength, corresponding to colors we perceive as violet to red.
What is an absorption transmission spectrum and what does it tell you about pigments?
An absorption transmission spectrum shows how much light is absorbed by a pigment at different wavelengths. It provides information about which wavelengths of light the pigment absorbs most strongly, which can help identify the pigment and understand its color properties.
How much of the electromagnetic spectrum is occupied by visible light?
Visible light occupies a small portion of the electromagnetic spectrum, specifically wavelengths between approximately 400-700 nanometers. This range corresponds to the colors we see in a rainbow, from violet to red.
What causes a prism to brake light into a spectrum?
A prism breaks light into a spectrum due to refraction, which occurs when light enters the prism and bends due to a change in speed. Different colors of light bend by different amounts due to their different wavelengths, resulting in the separation of colors into a spectrum.
How much of the electromagnect spectrum is visible light?

What is the absorbance spectrum of the given compound and where does the lambda max fall on the spectrum?
The absorbance spectrum of a compound shows how much light it absorbs at different wavelengths. The lambda max, or maximum absorbance, is the point on the spectrum where the compound absorbs the most light.
How much of the visible spectrum is contained in white light?
All of it. White light is the blend of all visible colors.
Why is prism spectrum more intense than grating spectrum?
A prism typically produces a more intense spectrum than a grating because it does not disperse the light as much, leading to higher light concentration on each wavelength. Additionally, prisms typically have higher efficiency compared to gratings in separating light into its spectral components, further contributing to the intensity of the spectrum produced.
Why astronomers study radiation beyond the violet end of visible light and beyond the red end of visible light?
Astronomers study as much of the spectrum of radiation as they can, and the visible spectrum is only a small segment of it.
What is the comparison between the size of the visible light spectrum and the size of the electromagnetic spectrum?
The visible light spectrum is a small portion of the electromagnetic spectrum, covering wavelengths from approximately 400 to 700 nanometers. The electromagnetic spectrum, on the other hand, includes a much broader range of wavelengths, from gamma rays to radio waves, spanning from very short wavelengths to billions of meters long.
Do LED lights on your motorcycle really make you more visable to other drivers?
Depends on the LED light. A 700 lumen LED Bike Light gives off roughly the same light as a 70 watt halogen but for much, much less power. Less lumens = less light = less visability to other drivers.
How much of the electromagnetic spectrum can your eye detect as light?
The human eye can detect a small portion of the electromagnetic spectrum, known as visible light. This range spans from approximately 400 to 700 nanometers in wavelength, corresponding to colors we perceive as violet to red.

How does the wavelength of the infared portion of the electromagnetic spectrum differ from that of the visible portion of the spectrum?
The wavelength of infrared radiation is longer than that of visible light. Infrared radiation has wavelengths ranging from about 700 nanometers to 1 millimeter, which are longer than the 400-700 nanometer wavelengths of visible light.
