The inner surface of a fluorescent light bulb is coated with a wavelength shifting material. Without this coating,   Question 3 options:   The light would be too dim for human eyes.   The light would be too bright for human eyes.   The light would not escape the bulb.   The light would not be visible to human eyes.
