It depends on the lightbulb. Regular incandescent light bulbs will not substitute for sunlight, however they do make full spectrum light bulbs (in both the regular socket style and in florescent style) that are intended to substitute for sunlight.
I've had some success overwintering my plants indoors using full spectrum bulbs but I've had just as much success using CFL's. CFLs drain less electricity, thus costing me less to have on all day (the plant still wants it's full requirement of sun; 8 hours for a full sun plant)
CFLs are also easier to find than full spectrums and, in my area cost, a little less at purchase.
No, because the lamp does not produce the type of light and heat energy like the sun produces and the plant can not perform its photosynthesis which is the process of which the plant grows, and it also depends on what type of plant you have.
Lamp light will enable the flowering plant to have a photosynthesis rate 8-10 times slower than sunlight. Consequently the plant will produce lesser starch and show minimal growth or flowering. It's even possible that the plant may die.
The plant can not live in a Closet with no lamp. With no light, the plant can not make glucose (C6H12O6) The plant will evenually die. The plant in the closet will die whether or not there is a lamp, but the one with the lamp will live longer.
put a lamp beside a sunlight sensor, and when the sun comes, the lamp turns on, if the sun goes away the lamp turns off
The plant which is kept in sun will grow normally whereas the plant which is kept in lamp will grow for for a certain period of time and the its growth will be re tarted and then the plant will eventually die. The reason behind is that the light of sun activate the photo system or the flow of electron by providing sufficient energy.but the lamp light will not have a sufficient energy to facilitate the flow of electron which is necessary for the chlorophyll pigment to perform photosynthesis
Lamp, because you need electricity for the lamp to work
not specifically sunlight, you can use a desk lamp but sunlight, being natural, is probably the best way.
That would depend on three things: # The amount of the Sun's radiation the plant is exposed to given your latitude, weather conditions and time of year - as well as the temperature. # The type of plant you use to test - different plants respond differently to different light frequencies. # The type of lamp you use to test - lamps use different compounds to produce light and so produce different spectrums of light. So some plants will benefit more from a particular light than others. All this considered the answer is both yes and no dependant on these points. For instance: A plant exposed to a low power lamp with the wrong light spectrum would be shoter than if it were grown outdoors at the equator. A plant exposed to a high power lamp with the right light spectrum would be taller than a plant grown outdoors in Scotland during the winter.
we use mercury lamp instead of ordinary lamp because ordinary lamp has many wavelengths when mercury lamp has single wavelength so in constant deviation we use only mercury lamp.
You Don't put in near the sun. Put in under a heat lamp instead.
it is used to see words and/or other objects when the sunlight cant reach it, so mankind created lamp.
for diffraction grating mercury lamp is used not sodium lamp.
