Answer 1

Answer:

Low frequency red light is used in Dark rooms because it does not expose the film, this is because the red light has low energy.

Explanation:

• Red light is used as a safe light in the dark room because it has lowest energy and cause least damage to the photosensitive material used in photographic plate.
• Among the lights of visible spectrum, violet has the highest frequency thus highest energy and red light has the lowest frequency and lowest energy.
• Wavelength being inversely proportional to frequency ,is highest for red light and lowest for violet light.
• The frequency and energy level of the colors decreases as: Violet> indigo>blue> green> yellow>orange>red.
