Question

For the element barium, which wavelength of light is produced by the largest drop in energy for an electron? Which represents the smallest drop? Explain.

Answer 1

The wavelength decreases in the order:

Red, orange, yellow, green, blue, indigo, violet

Because a larger transition in electron state releases a larger amount of energy, it will produce light of lower wavelength. Conversely, a smaller change in energy will release light with a higher wavelength.

Step-by-step explanation:

Answer 2

The colors of visible light are due to different wavelengths. The wavelength decreases in the order:
Red, orange, yellow, green, blue, indigo, violet

Moreover, the lower the wavelength of a wave, the greater the energy it has. Because a larger transition in electron state releases a larger amount of energy, it will produce light of lower wavelength. Conversely, a smaller change in energy will release light with a higher wavelength.
