Which color light has photons of the greatest energy?
A. Blue
B. Yellow
C. Red
D. Green
To determine which color light has photons of the greatest energy, we need to consider the relationship between the color of light and its corresponding wavelength or frequency. Higher energy corresponds to shorter wavelengths or higher frequencies.
The visible light spectrum ranges from violet to red, with violet having the shortest wavelength and highest energy, and red having the longest wavelength and lowest energy. So, among the given options, the color with photons of the greatest energy would be:
A. Blue
Blue light has a shorter wavelength and higher frequency compared to yellow, red, and green light. Hence, blue light has photons with the greatest energy.
