Light intensely affects plant growth. Since plants cannot eat, they must get their nutrients from the sun. If they have plenty of light, they can perform photosynthesis and feed themselves. If not, plants will not live long.
The effect on plant growth is, Most plants tend to grow quicker and bigger when you rise the level of the light bulbs (watts) up to about one half of full sunlight. So if you can increase the brightness of the bulb it will grow faster and bigger.
To maximize production per watt a grower must keep manage the light close to the plant but not burn the plant. When using grow lights for plants the intensity of the light and the light's distance from the plant must be considered.
Light intensity doubles for every 6 inches closer an HID is to the plant. Therefore using several small lamps with lower wattage can often cover more real estate better than one large, high wattage lamp. Some benefits include:
The most common HID lights for growing are metal halideand high pressure sodium.
Metal Halide (MH)
Metal halide grow lights for plants produce an abundance of cooler, blue light. This light promotes leafy, bushy growth making makes MH bulbs good for early to vegetative phase of a plant. These bulbs have about 12,000 hours of life or two years of 18hour/daily use, the recommended hours for vegetative growth.
It's a good idea to track the bulb's life so you know when to replace it. The bulb's gradual decline in intensity will rob your plants of needed light spectrum so don't wait till the bulb burns out before replacing it. And keep spares on hand.
MH bulbs also come in super metal halides which go to eleven. Super metals put out approximately 15% more lumens.
No, shade plants have a higher rate of photosynthesis at lower light intensities. They are more adapted to use the end range of light (red, 730 nm) that is present in shady conditions than sun tolerant plants are.
As light intensity increases then the rate of photosynthesis increases until a point is reached when the rate levels off. Beyond this point is called the light saturation point of photosynthesis.
Ensure the plant has adequate light intensity and that the Magnesium levels (macronutirent) is correct
0% light and 25% light
Higher light intensity increases the rate of photosynthesis and vice versa.more intense light means more energy in the light, so the chloroplasts get more energy from light, making photosynthesis go faster
The higher plants percieve photoperiod by their leaves. The intensity and quality of light determine the duration of photoperiod for inducing flowering.
No, shade plants have a higher rate of photosynthesis at lower light intensities. They are more adapted to use the end range of light (red, 730 nm) that is present in shady conditions than sun tolerant plants are.
it just depends on the shade of blue and purple. if it is a dark purple and a light blue, then the light blue would have a higher intensity. if you look at any shade, the one that is brighter has the higher intensity of the two.
less light intensity gives a better vision
Light intensity affects voltage because the higher the intensity of light, the more volts are produced. It works exactly the same way in the case of: the lower the light intensity the less volts that are produced.
If the plant has enough chloroplast to accept the light intensity, it'll continue to grow strong accordingly. It'll develop stronger leaves, stem, and darker in green color foliages. It'll reach a peak where light saturation occur when the plant no longer can grow any stronger even with higher light intensity. Increasing the light intensity further could hurt the plant.
In general, net respiration (Rnet) in plants increases as light intensity increases.
Photorespiration occurs in dry situations, where there is intense light. Desert plants are a great example. Therefore, no, photorespiration is not independent of light intensity.
Loudness is the colloquial term and intensity is the scientific term. More the intensity higher the loudness. Same way in case of light, higher the intensity of radiation, we call colloquially that as more brightness.
The more electrical energy there is there is more power or wattage which means that the light intensity is higher if there is more electrical energy.
Its applicable for all spectroscopy, higher is the substance higher is the intensity of light emit or absorbed. Taking some known amount and calculating the intensity ,finally ploting a graph of them . Then for our unknown we can measure intensity and extrapolating graph we can know the amount quantitatively Don't be confuse with intensity and frequency of light. Intensity says about the amount and frequency about energy.
The signal is encoded as light; the light changes intensity, for example a higher intensity for a one, or a lower intensity for a zero. (In practice, more complicated encoding schemes are used.)
