What do the values or R, G, and B mean in terms of the energy of light.
Energyblue>energygreen>energyred
R = red light (wavelength = 650-700nm)
G = green light (wavelength = 500-550nm)
B = blue light (wavelength = 450-500nm)

to calcuate Energies, use E = hc/wavelength, but be sure to convert wavelength into meters first.

The values R, G, and B in terms of light refer to the primary colors used in additive color systems, such as those used in digital displays. These colors are Red (R), Green (G), and Blue (B). Each color represents a specific range of wavelengths within the visible light spectrum.
In terms of energy, the R, G, and B values correspond to the intensity of light emitted or reflected by each color channel. The higher the value, the more energy is present in that particular color channel.
To explain how to measure the energy of light using R, G, and B values, we need to understand how the intensity of light is quantified in digital image processing. In digital image formats, such as JPEG or PNG, each pixel in an image contains information about its color using RGB values.
Here's a step-by-step process to measure the energy of light using RGB values:
1. Capture an image or retrieve an image file that contains the desired light source.
2. Convert the image file to a suitable format that can be processed, if necessary.
3. Read the RGB values of each pixel in the image.
4. Calculate the total energy of light for each color channel (R, G, and B) by summing up the RGB values for all pixels.
5. Analyze the resulting values to determine the relative energy levels of each color channel.
Please note that this method provides a rough estimate of energy based on the intensity of light recorded by digital sensors. For more accurate measurements, specialized instruments such as photometers or spectrometers are typically used.
