Plants grow well in the red end of the light spectrum. Fluorescent tubes come in many light outputs. Cool white which is in the blue end of the spectrum down to the warm white which is on the red end. Manufactures make a growlux tube which is used specifically for plant growth. Store meat counters are starting to use these tubes for display lighting as they enhance the red colouring of the meat on display.

Can a pickle light up a light bulb?
Yes, a pickle can light up a light bulb if it is used to complete an electrical circuit. Pickles contain electrolytes that can act as conductors of electricity, allowing them to power a simple circuit and light up a small light bulb.
How many watt does a 60 watt light bulb use if turn it on and off?
If you turn a 60 watt light bulb on and off, it will still consume 60 watts when it is turned on. The act of turning it off does not reduce its power consumption when it is on. However, when the light bulb is turned off, it consumes no power.
Why does a light bulb filament act as resistor?
The filament of a light bulb isn't like a resistor ... it is a resistor. The only difference from the ones on circuit boards is the it's designed to operate at a much higher temperature. So hot that it glows. The glass envelope is there to prevent oxygen from getting in and promptly burning it. When the filament becomes too hot it breaks breaking the current that was lighting it in the first place. That is why the light bulb "burns" out.
Is it possible to light a bulb with raw peanuts?
Yes and no. If the peanuts are moist, not dried, they will act an electrolyte between two dissimilar metal electrodes - zinc and copper for instance - and form a cell that would power a low-volt lamp. The peanuts would be best if ground into a paste to ensure good contact and a continuous path between electrodes. The is also possible with something like a whole apple or potato as well, just push the electrodes in, but what is really powering the lamp are the chemical reactions at the electrodes.
How does a fluorescent light work?
Mercury, Phosphorus, and Argon are arranged inside of the glass bulb in such a way that it reacts in a specific way. The mercury vapour is heated to form a gas and then high voltage passed through the tube from one end to the other. The gas emits ultra violet light. The inside of the tube is coated with a phosphor coating which lights up (fluoresces) when UV hits it, causing it to emit visible light. Tweaking the chemical composition of the phosphor coating, can provide different shades and colours of light. No coating, gives UV (black) light. There are two heating electrodes at each end of the tube. On switch on, current is applied through both heaters via a ballast coil and the circuit completed through a bimetal switch (starter). The heaters heat up, then the switch opens, causing a high voltage surge from the ballast. The high voltage causes the mercury vapour to conduct electricity through the tube, at low resistance, causing it to emit UV light. The current is limited by the ballast coil. If the vapour fails to strike, then the bimetal switch cools and then closes again, starting again, until the tube 'strikes'. This is what causes the lamp to flicker before coming on. Once the tube has lit, the low resistance path through the tube effectively takes the starter and heater out of circuit. The heater ends act just as electrodes into the gas filled tube.
Can light blub act as sun and make flower?
If you use fluorescent lighting you will receive flowers on your plants. A regular light bulb will not do the trick. Buy a cheap shop light fixture and put in two long tubes one cool and one warm. Yes- artificial light can be used to grow plants, including flowers. A light bulb may not make enough light. Search for grow light or plant light.
Is a light bulb a conductor?
No, a light bulb is not a conductor. A light bulb is made of materials that act as insulators, such as glass and tungsten. The filament inside the light bulb serves as a resistor to generate light when electricity passes through it.
What would a light bulb act as in a circuit?
A light bulb would act as a load in a circuit. It transforms electrical energy into light energy and heat when current passes through it. It offers resistance to the flow of current, causing it to light up.
Can a pickle light up a light bulb?
Yes, a pickle can light up a light bulb if it is used to complete an electrical circuit. Pickles contain electrolytes that can act as conductors of electricity, allowing them to power a simple circuit and light up a small light bulb.
Is it true a light bulb acts as resistor in the flow of electrons?
While a light bulb does not technically act as a resistor, in practice it does impede the flow of electrons due to its resistance. As electrons pass through the filament of the light bulb, they encounter resistance, which causes them to release energy in the form of heat and light. This phenomenon is what allows the light bulb to produce light.
What is the hypothesis of a light bulb using a lemon?
The hypothesis regarding using a lemon to power a light bulb would be that the acidic juice of the lemon can act as an electrolyte to facilitate a chemical reaction with the metal electrodes of the light bulb, generating enough electricity to produce light.
What was George Washington's role in the judiciary act of 1789?
He invented the light bulb
Why does a light bulb get lit up by a lemon?
A lemon can act as a battery due to its citric acid content reacting with the metal electrodes in the light bulb. The electrolytes in the lemon facilitate a flow of electrons, creating a small electric current that can light up the bulb.
Do a light bulb acts as a resistor in the flow of electrons?
No, a light bulb does not act as a resistor in the flow of electrons. A light bulb converts electrical energy into light and heat through the resistance of its filament. Resistors are passive components specifically designed to control the flow of electric current in a circuit.
What 2 forces act on a seedling to make it grow?
light and water
What household items can you make a light bulb light up with?
You can create a simple light bulb circuit using household items like a battery, a light bulb, and wires. For instance, you can use a AA battery, connect it to the light bulb's terminals with conductive wires or metal objects, such as paper clips. Additionally, some fruits, like lemons or potatoes, can act as a battery when inserted with two different metals (like copper and zinc), generating enough voltage to light up a small bulb. Always ensure safety when experimenting with electricity.
What is the job of a bulb in a circuit?
The job of the bulb in a circuit is to convert electrical energy to light. It's called the load in the circuit.
