The radiation that a laser emits ... whether it's visible light, infrared, or microwave,
has all the same physical characteristics as electromagnetic radiation from other
sources has, including speed.
yes, they are both forms of light and travel at the same speed
Yes, they travel some fast!
lighting travels at the speed of light
983,571,056.43045 feet/second in a vacuum.
It travels at approx 220,000,000 metres per second.
Like any distance, it depends on how fast you are going. At the speed of light it would take 4,000 years to travel that distance.
Yes, they travel some fast!
As long as the artificial light you use emits the full-spectrum of light, the plant can't tell if it is natural or artificial. What you can do with artificial light to promote plant growth is extend the length of the "day". If you leave the lights on all day and night the plant will grow faster, but keep in mind that plants also depend on cues from day length, nighttime temperature and soil conditions to "know" when to set flowers and fruit, how many flowers to set and how much sugar to concentrate into the fruit. So you might get a really fast, really tall, really green plant with little fruit. In Addition: i agree the really tall really green plant that grows to fast because you have had the artificial light on for more hours than natural light is a condition called "leggy" and this type of plant is a very unhealthy plant. What you want is a stocky thick at the base plant.
Copper is opaque to light - light can not travel though it.
If you use blue light in the day and red light at night it should grow twice as fast but, I would use red.
the speed of light
it can travel from 380nm [nanometres] to 740nm
Darkness is the absence of light and will therefore travel at the speed of light (6x108m/s)
light travels faster.
yes
at the speed of light
Speed of light.
Approx 9.46 trillion km.
