The wavelength of the indigo light can be calculated using the formula:
wavelength = speed of light / frequency
The speed of light is approximately 3.00 x 10^8 m/s.
So, substituting the given frequency into the formula:
wavelength = (3.00 x 10^8 m/s) / (7.08 x 10^14 Hz)
wavelength = 4.23 x 10^-7 meters or approximately 423 nanometers (nm).
Therefore, the wavelength of indigo light with a frequency of 7.08 x 10^14 Hz is approximately 423 nm.
