Which colored light bulb, red, orange, yellow, green, or blue, emits photons with the least energy? Explain.
(b) Which emits photons with the greatest energy? Explain
E = hc/lambda
So the photons with longest wavelength have the least energy. Photons with the shortest wavelength have the highest energy. So red is where and blue is where on the energy chart?
To determine which colored light bulb emits photons with the least energy, we need to consider the wavelengths associated with each color. Light with longer wavelengths has lower energy, while light with shorter wavelengths has higher energy.
Let's start with the color red. Red light has a longer wavelength compared to other colors, such as orange, yellow, green, and blue. Therefore, red light emits photons with the least energy among the given options.
Now, let's determine which colored light bulb emits photons with the greatest energy. Among the colors orange, yellow, green, and blue, blue light has the shortest wavelength. As mentioned earlier, shorter wavelengths correspond to higher energy levels. Thus, the blue colored light bulb emits photons with the greatest energy.
In summary:
- The red colored light bulb emits photons with the least energy.
- The blue colored light bulb emits photons with the greatest energy.
