Answer:
The wavelength is about 666.2 nm.
The color is red.
Step-by-step explanation:
Recall the relationship between frequency and wavelength:
Solve for wavelength λ:
Substitute and evaluate. Note that 1 Hz = 1 s⁻¹:
Therefore, the wavelength of the light is about 666.2 nm.
This corresponds with the red region of the visible spectrum.
