Explain artifical source of light with two examples
Answers
Artificial light, as opposed to natural light, refers to any light source that is produced by electrical means. Artificial lighting has many different applications and is used both in home and commercially. Artificial lights are available in a wide variety of shapes, sizes, colors of light emitted, and levels of brightness. The use of artificial lighting is crucial in agriculture and gardening, particularly in indoor cultivation.
Additionally, care should be taken when deciding how much lights to expose plants to as all plants differ in light intensity needs. Last, but not least, light duration should also be considered. Some plants need varying amounts of light and darkness for proper growth. This is particularly true in flowering plants. For example, short-day plants will thrive on less than 12 hours of light a day. However, long-day plants need at least 14 to 18 hours of light per day
