Which red line shows the same action spectrum corrected for the unequal number of photons emitted across the visible spectrum?
The red line in the second graph shows the same action spectrum corrected for the unequal number of photons emitted across the visible spectrum.
How does radiation change across the electromagnetic spectrum?
The amount of radiation changes across the spectrum.
How does the incandescent light bulb work?
Current passes through the filament of the bulb causing it to heat up. When it heats up, it becomes so hot it incandesces. That means it radiates light. When the filament is white hot, it radiates light across much of the visible spectrum. Incandescent lights also waste a lot of energy which comes out as heat.
A simile with rainbow and color pencils?
the rainbow was like an aray of colored pencils scattered across the confetti
Why does an incandescent light bulb produce a continuous spectrum that seems to favor red?
Actually the peak of the radiation from an incandescent light bulb is in the near infrared, not the visible spectrum. The visible light that you see is the falling upper sideband of this: very strong in the red and declining until it is weak in the blue and violet end with a very small amount of radiation in the ultraviolet. The lower sideband extends across the infrared and into the far infrared. Well under a third of the emitted electromagnetic radiation of an incandescent light bulb is visible light, most is infrared.

Why are the rainbow lorikeets rainbow colored?
Although rainbow lorikeets are literally all of the colours of the rainbow, their colouring makes them almost impossible to detect in their natural habitat of Australian native plants, with their colourful flowers. Their colours make them well camouflaged.
What advantages in structural biology are gained by the synchrotron?
A small part of the electromagnetic spectrum which ranges from the long wavelengths-radio waves, microwaves and infrared through the visible spectrum to the short wavelengths of ultraviolet light, X-Rays and gamma rays. Synchrotron light is unique in its intensity and brilliance and it can be generated across the range of the electromagnetic spectrum.

Is it possible to have a triple rainbow across the sky?
no
What spectrum does the sun emit?
The Sun emits radiation across almost the entire electromagnetic spectrum.

How big is a visible light wave wavelength compared to something you can physically see?
OK. Here goes:-- The diameter (distance across) a US dime (10¢) is 17.91 millimeters.-- The wavelength right in the middle of the blue region of the visible spectrum is 500 nm.-- 35,820 waves of blue light lined up end-to-end fit all the way across a dime.
How do you convert the photometric unit to radiometric unit?
There is no direct conversion because they are used to measure two different things. Radiometric units are used to measure radiant energy across the entire spectrum, whereas photometric units are used to measure visible light as preceived by the human eye. As the eye's sensitivity varies across the visible spectrum (being most sensitive to green light, and least sensitive to red and violet light), the conversion between the two systems of measurement varies according to wavelength at which it they are being compared.
Theoretically What is the maximum possible luminous efficacy?
683 lm/w for a pure monochromatic green light source at a single wavelength of 555 nm. This is because a lumen (lm) is measured according to sensitivity of the human eye and the eye is most sensitive at 555 nm. For a wide-spectrum "white" light source, the theoretical maximum is about 280 lm/W if the luminous energy is evenly spread across the visible spectrum. The number can vary slightly depending on the limits chosen for the visible spectrum and how white light is defined.
