Low-Frequency red light is used in dark rooms because it does not expose the film. This is because the red light has a low frequency or energy
Why is this correct?
Low-frequency red light finds application in darkrooms as it possesses minimal capacity to activate or impact the light-sensitive emulsion on photographic film. This reduced activation arises from the extended wavelength of red light.
Thus, the blank in the statement can be suitably completed with "energy" or "frequency," as red light's low energy and frequency, compared to other colors in the visible spectrum, result in its diminished effectiveness in exposing photographic film in darkroom environments.
