Question

a spaceship is designed to support animal life for a multiyear voyage to the outer planets of the solar system. plants will be grown to provide oxygen and to recycle carbon dioxide.; since the spaceship will be too far from the sun for photosynthesis, an artificial light source will be needed. what wavelengths of light should be used to maximize plant growth with a minimum of energy expenditure?; a) full-spectrum white light; b) green light; c) a mixture of blue and red light; d) yellow light; e) uv light

Answer 1

Mixture of blue and red light

Step-by-step explanation:

This wavelength of light will maximize plant growth with minimum of energy expenditure compared to the rest of the options

Answer 2

uv light is light that covers the electromagnetic spectrum from infrared to near-ultraviolet, or all wavelengths that are useful to plant or animal life
