What else can I help you with?
Can a plants live ona light bulb light or does it needs natuarl light from the sun?
Plants do not always need sun light to give it the energy it needs, there are lots of special light bulbs that you can but in lots of gardening shops, they usually come with the whole flower itself in a little packet thingy. So yeah, it can live on light bulbs but on special ones
Why some bulbs give out yellow light and others white?
The color of light emitted by bulbs is primarily determined by their design and the materials used. Incandescent bulbs emit a warm yellow light due to the heating of a tungsten filament, while fluorescent and LED bulbs can produce a range of colors, including white, depending on the phosphors or diodes used. The perceived color temperature, measured in Kelvin, also influences whether a bulb appears yellow (lower Kelvin values) or white (higher Kelvin values). Different applications and preferences lead to the use of various bulb types for desired lighting effects.
Do all light bulbs give off UV light?
All lamps will give off UV but incandescent lamps will give-off unmeasurably small amounts. Discharge lamps essentially all contain mercury and mercury in the discharge gives off UV. However, most lamps are enclosed in UV-absorbing glass, either as primary containment or as an outer enclosure (bulb), so very little gets beyond the outer bulb. If any lamp emits more then almost no UV, it has to be marked (R in the US), and a warning given that it cannot be used in an open fixture - in other words, it must be used behind a UV absorber (usually what is called soft glass - similar to normal window glass).
True or false a planet is a body that gives off light of it owns?
A planet only reflects light from a star like our Sun. Earth is a planet and from experience it does not shine. Stars give off their own light.
Can you give me a science project for a 6th Grader?
A good science project for a 6th grader would be about magntism, like does the bigger the magnet mean the gravitational pull will increase if you try to pick up bigger things than that.
How many 75 watt fluorescent bulbs are needed to give as much light as a 75 watt incandescent bulb?
A 15-watt fluorescent should produce about as much light as a 75-watt incandescent.
What watt fluorescent bulb can you use to replace a 60watt incandescent bulb?
fluorescents are about 5x as efficientso a 12W will give about as much light
Do CF light bulbs produce as much heat as incandescent bulbs?
No, compact fluorescent bulbs run much cooler that an incandescent bulb. A CF bulb can be unscrewed when the lamp is on whereas an incandescent will give you a bad burn if this is tried.
Are light bulbs really efficient?
Normal incandescent bulbs produce a lot of heat as well as light, so are not so efficient as low energy bulbs which can give the same light but consume much less electricity
Do higher wattage bulbs give a brighter light?
Yes, in general, higher wattage bulbs produce more light than lower wattage bulbs. However, the brightness of the light also depends on other factors such as the type of bulb (incandescent, LED, etc.) and the design of the fixture.
Can you use 40 watt in a fluorescent light in place of a 32?
Yes, the wattage is just the power consumption. A 30 watt Fluorescent will give more or less the same light as a incandescent bulb or 60 watts, which is the limit for your fixture for incandescent bulbs.
What appliances gives light?
Appliances that give light include lamps, light fixtures, ceiling lights, and flashlights. These appliances use various sources of light, such as incandescent, LED, or fluorescent bulbs, to illuminate a space.
Why use a heater to warm up a room instead of a light bulb?
Light bulbs use a ton of energy. People have been lately switching to the fluorescent light bulbs which use less energy and last longer and don't give off nearly as much heat.
How a fluorescent light bulb works?
Fluorescent light bulbs have a gas inside of them called Mercury. The way that the light bulb works is that it uses electricity to "excite" the mercury atoms. This causes the mercury atoms to give of short wave ultraviolet light. this causes a phosphor which is any substance that can illuminate to fluoresce or emit light.
How can one accurately measure the brightness and efficiency of fluorescent bulbs?
To accurately measure the brightness and efficiency of fluorescent bulbs, one can use a device called a light meter to measure the amount of light emitted by the bulb in lumens. The efficiency of the bulb can be calculated by dividing the number of lumens produced by the amount of power consumed in watts. This will give you a measure of how effectively the bulb is converting electricity into light.
What light bulbs provide the most natural light?
Any natural light bulbs that use incandescent lighting will work well, and give off a rounder light than the "sterile white" lighting of normal bulbs.
Which bulb lasts longer an incandescent light bulb or a compact fluorescent light bulb?
A regular incandescent bulb uses a lot more energy than a compact fluorescent to produce the same amount of light. Most energy used by an incandescent bulb is wasted as heat which does not give off visible light. Incandescent bulbs are cheaper to buy, but they have shorter lifetimes than other alternatives.
