- Q: We understand light is made up of particles. A beam of light particles would have weight of some amount, if so could Light push or propel an object?
- Does Light Have Weight
- Q: What brand of garden lights better?
- Solar garden lamp manufacturers in the design, attention to its beautiful lighting and its brightness required to design its height is generally so high
- Q: is there a way to measure roughly the light intensity coming out of a torch in a dark room? preferably without a light meter
- In regard to Anal kumar S method of using photoelectric effect to help determine the intensity, I think it is not a good way to determine the intensity of the light from the torch. The type of metal emitter used is important as if the light from the torch, being not monochromatic, have certain light with a frequency below the thrash old/cutoff frequency of the metal, then that frequency of light is as good as useless. Furthermore, this experiment is hard to carry out. The collector plate will not be able collect most of the photoelectric electrons as the electrons will ionise the nearby air particles. This will affect the current measured and the intensity of light measured will carry a large percentage error. The way to prevent this is to conduct the experiment in a vacuum container. Also, the current measured will most likely be small due to the relatively low frequency of the light from a normal torch. A very sensitive ammeter is needed to detect the current. However, I am not able to think of better ways to measure the intensity :p. Maybe use a spectrometer or use a light dependent resistor and, of course, you need to know the characteristic of the resistor.
- Q: uses of polarisation, how is polarised light produced
- sunglasses, windows in air craft, holograms,
- Q: I bought a new light for my beta fish tank that turns out is a night light that is green. Will this harm my fish?
- Well as far as I know your Betta should be fine with that green light. I can't see any way it could harm him or anything. I guess if it makes you feel better though you could always just go get a regular colored light bulb for him later on.
- Q: Are recessed (can) lights rated for outdoor use? I plan on installing recessed lights on a porch.Would this violate code?
- Sure, okorder /... It lists various recessed lighting applications and has links to sites that sell various recessed lighting products.
- Q: not the usual clear white light, but yellow-gold porch light, new decor??
- it a bug bulb, bugs dont like it as much.
- Q: can you explain to me everything you know about the light spectrum?? thanks(:
- spectrum= group of waves light spectrum group of visible light waves part of the electromagnetic spectrum that we can see ROYGBIV speed of light speed= frequency X wavelength color can be expressed as wavelength or frequency objects are the color that they reflect light can be transmitted, reflected, absorbed filters allow one color to go through ultraviolet is above human seeing, infrared is below human seeing
- Q: When light is refracted from air to flint glass?
- Some is reflected at the boundary, usually around 4% if I recall correctly.
- Q: In a indoor large class room setting, need a low heat lighting solution for the podium area. So the speaker is not too hot, yet the light is bright enough for filming. Thanks!
- The new fluorescent bulbs don't give off heat, and although they cost more, they use a lot less electricity so are said to save money. The first ones I bought for the house were too bright, like daylight, and not the mood I wanted in my living room. I believe Lowes could help you with just the right thing.
