- Q: and can a bean plant with out light even grow?
- A bean plant without light might outgrow one with light for a tiny bit, because it would still be desperately seeking light, and not think it's grown tall enough to get it yet. But a plant without light doesn't have any more energy than was contained in the seed, and until leaves are grown and they can receive light, the plant doesn't have the ability to make more energy (even if it's getting fertilizer and water). Without light, all plants are doomed to die, even though their seeds get them started.
- Q: uses of polarisation, how is polarised light produced
- sunglasses, windows in air craft, holograms,
- Q: Theoretically, What would happen if we made Light Particales travel faster than the speed of light?Exaple: Turning on a lamp and the light Particles move faster than they should, What would we see or feel?
- 1) It can't travel faster. 2) If light traveled faster than light, light would have to travel infinitely fast. It would get places instantly. The earth would be bombarded by all the light in the entire universe, not just the observable universe, the whole universe.
- Q: Or light photons, i don't know.And why?
- Light is a by-product of matter -- not matter itself. Curiously, however, sunlight does have weight. It amounts to about 1 pound per square mile.
- Q: I have a physics project and it's about reflection and I need to know about Opaque, transparent and translucent materials, Formation of shadows, Rectilinear propagation of light, Laws of reflection, Ray diagrams, Plane mirrors and mirrors at an angle. Someone Please explain this to me so that if I can understand this then I can present this in my own understanding.
- Transparent light easily passes through transclucent dim opaque no light passes
- Q: Light photography such as light trails, light art, etc. Wideangle or telephoto?
- This would depend on the intensity of the light you're trying to capture in trails, how close you can position yourself to the action and how you want to compose your shot. Assuming the source isn't too faint then almost any lens will work as long as you use a suitable aperture setting and long enough shutter speed. With each lens it will take some experimentation at different camera settings to find the ideal recipe for producing the best light trail images.
- Q: What is the height of the garden lamp?
- Although the solar garden lights just as an outdoor landscape lights, but it is clear that it is a very good environment and economic benefits.
- Q: light years to seconds
- a light year is a unit of distance not time
- Q: Light bulb manufacturers like GE,Phillips sell bulbs as soft white and cool white. the soft white bulbs emits yellow light actually.and the cool white bulbs emits light that are really white.
- The color of light is measured in Kelvins, 1000 Kelvin represents candle light while 5000 Kelvin is noon daylight. Light globes called soft white or warm white have a color temperature of 2700 Kelvins and emit a pale yellow light, cool white is 4000K which gives that bright white light while daylight at 5000 K gives a bright white light with a bluish tinge. Yellow light like high pressure sodium globes used as fog lights in street lamps have a color temperature of 2100 K.
- Q: Why is it that light can't travel through everything. On my psp there is an orange charging light that when you look at it from a different angle you can see these spikey things coming from it. When i put my hand near it the light shines through. So cant light shine throught everything?
- Light can't penetrate through every object,that is why some objects are called opaque an also,when light travels for so long,it loses loads of energy or electrons(as in an element).That is why light from the sun can not travel to other farther planets in the solar system.
