Solar energy is one kind of green energy from the sun which is environmental protection, noise free, renew and endless. When the solar panel absorbs the solar energy, it makes photovoltaic, then the solar controller converts it into electricity and the light source of LED, scanty light and the sodium lamp will lighting. It is charged on day and lighting at night. It will more benefit from one-off investment to this product.

- Q: explain why we notice the Doppler Effect for sound but not light.
- well there are two ways to produce the Doppler Effect with sound 1) the listener can move toward (or away) from the source effectively changing the speed at which the sound waves are intercepted 2) the source can move toward or away from the listener effectively changing the wavelength of the intercepted waves at low speeds the effects are nearly the same but consider moving at the speed of sound consider condition 1 where listener moves away from the source at the speed of sound the result will be that no sound is heard but under condition 2 if the source moves away from the listener at the speed or sound the result will be a drop in frequency of one octave (1/2 original frequency) now with light the perceived speed is a constant, c, it is always c ! and no matter whether the observer or the source is moving the speed of light is a constant with respect to the observer so only condition 2) of the Doppler Effect prevails for light as a result if observer and source are moving apart, wavelength increases - red shift if observer and source are coming closer, wavelength decreases - blue shift Yeah, there is a Doppler Effect for light ! but just the one kind
- Q: is nightshading your tail lights illegal in mn?
- It is legal! Don't let anyone tell you otherwise.. just don't go too dark. They just need to be able to see light coming through. I have my tail lights night shaded and never have any problems.
- Q: What causes light to refract
- When a light passes from one optical medium to another of different optical densities, then it will refract. The reason is that, the frequency 'v' of light does not change, but the wavelength 'λ' will change. Since, c = vλ, c will change accordingly. This change in speed of light causes it to refract.
- Q: no joke, what is the thing called that a light bulb is connected to?
- complicated matter. lookup on yahoo and bing. that can assist!
- Q: I'm picking out a new light fixture and i need help!
- The light bulbs in the fixture determine the kind of light you will have. GE makes light bulbs for natural light. You will have to go to a lighting store to find a good selection.
- Q: Can exercising make a period lighter
- Yes it will. But if you overdue it your period will stop compleatly and thats really unhealthy.
- Q: Where does the light of a candle come from and if you blow out the light, where does it go to?
- Scientifically, the light has passed you because the source of the light has gone. The light itself has transformed into wind, or what ever broke the light, and that's where the light went. Metaphorically, the light died, and nobody can prove to you where it went, but people will just have differing opinions. The light came from your parents, and where.
- Q: what is the weight of ray of light?
- In Euclidean space-time...yes light does have mass. It has zero rest mass...but it doesn't exist at rest. Special relativity equations yield a relativistic mass increase to 0/0 as it approaches the speed of light, and 0/0 can equal any finite number. We know an equation of m=h*f/c^2 for it to have because we can also look at mass-energy equivalence as well as relativistic momentum to determine its effective mass when at the speed of light. Light exhibits both inertia AND participates in gravitation, and we have measured this in experiment for confirmation, hence it has mass, and weight if nearby a gravitational field. We know it has inertia because of the phenomena of radiation pressure. We know it has participation in gravity because of the phenomena of gravitational lensing of distant starlight around our sun. What is a ray of light specifically? What is its population of photons? What is its intensity? If you want to speak about the smallest unit you can even call light, that is one photon. Its effective mass depends on its frequency, and can be calculated as: m = h*f/c^2 And its effective weight in Earth's gravity: W = h*f*g/c^2 For single photon of green light at 600 THz, this yields: m = 4.42*10^(-36) kg Weight in Earth gravity: W = 4.33*10^(-35) Newtons
- Q: what is light indeendant???as much information as possible please and what is the equation for it
- Light independent is the second cycle of photosynthesis (the first one is light dependent). Just like its name, this process doesn't need light to happen. The equation for the reaction: 6H2O + 6CO2 + Light energy
- Q: i used to smoke marlboro lights, but i'm starting to like smooths. what's the difference between them?
- not much.. both do have the commonality that they will give you lung cancer and you will die leaving behind all your loved ones... STOP SMOKING
