Can a solar flashlight be recharged with a light bulb?
Yes, although it will take a lot longer than in sunlight. The particles of light are called photons and each photon carries a certain amount of energy. As the photon hits the photovoltaic cells of the solar panel, the energy they contain is converted into electrical energy by the excitation of electrons in the board. The stronger the light, the more energy.
What does plasma have to do with stars?
plasma is created because of the extreme pressure on the gases the star contains... these gas molecules rub and bash into each other and are so tightly together that light is given off.
Where does the energy for the fusion come from in red giant star?
Nuclear fusion comes from the sun it is a "fusion" of hydrogen pairs that make helium and the helium has to many electrons so those extra turn in to photons and come to earth from the sun as heat and light. Or that's what i have heard. So this happens in the sun very rapidly many photons are sent to the earth each second.So the answer (or what i think is the answer) is it comes from the sun!
An instrument used to view different colors of light produced by each type of light bulb is called a?
spectroscope
When the light reflecting on the moon appears to be increasing each night?
waxing
Which has more photons a bright red light or a dim blue light?
Whatever the colors are, the brighter light results from the beam of more photons. But each individual blue photon carries more energy than each individual red photon.
What is the difference between Coherent and incoherent light?
coherent light is a light in which the electromagnetic waves maintain a fixed and predictable phase relationship with each other over a period of time. Additional Information (S) Incoherent light contains may different wavelengths and amplitudes of light, such as light from a light bulb. Coherent light is a beam of light where all of the photons are the same frequency and interval. If you think of photons like people, a laser is a coherent group of photons like a column of soldiers marching in a long parade, whereas incoherent light is more like everyone exiting from the movie theater.
How are photons of light different from each other?
They differ in wavelength, E =hf=hc/w.
How are wavelength and frequency and energy related for photons of light?
They are inversely proportional or relationship to each other.
All light has the same amount of energy?
This is a tricky question because there is more than one form of energy in light. There is the energy that each particle of light (the photon) has and there is group energy which is the sum total of all the photon energy as they travel as a group (like in a laser beam). But the good news is that the answer is FALSE for both the photon and group energies. Photon energy depends on the photon fundamental frequency. And the higher the energy the bluer the color, which can run from red to violet. Those photons in the violet color have higher energy than photons in the red color frequency. And group energy is just the sum of all the photon energies in a group, like a light beam from your flashlight (aka, torch). So for a given mix of photons, the more photons in the group the higher is the group energy level. What we call light intensity (e.g., bright or dim) depends on the group energy with high energy equating to high intensity.
What makes gold shiny?
Light is composed of very small packages of electromagnetic energy called photons. We are able to see objects because light photons from the sun (or other light source) reflect off of the atoms within the object and some of these reflected photons reach the light sensors in our eyes and we can see the objects. It takes many millions of photons entering our eyes each second for us to view the world. When photons of light hit the atoms within an object three things can happen. First, the photons can bounce back from the atoms in the object; we call this reflection. Second, the photons can pass through an object such as glass and we call them transparent. Three, the photons can be stopped by the atoms within the object and the photon energy is converted to heat; we call this absorption.
Why does an element give off light of a particular colorwhen flame test is being conducted?
This is because each element has different photons (bundles of light) it gives off during reaction or energy transfer. For example, lithium has primarily red photons, so you see a lithium flame as red.
If the light bulb from number 10 radiates 100 watts times 100 joules per second of photons. How many photons per second are radiated?
Given the wavelength of the photons from above, 3000 nm you just calculate how many joules each photon has and divide that into 100 joules per second.
What type of light contains a filament?
All kinds of incandescent lamp, and all types of light bulb contains filament. But there are several kinds of filament applied each type of light bulb.
What is white light compose of?
Light, no matter what color, is composed of photons. Each photon has a specific wavelength (color) associated with it. Because of the way our eyes work, at least three different wavelengths are required for us to perceive light as "white".
How does the energy of three photons of blue light compare with that of one photon of blue light from the same source?
If the color (frequency, wavelength) of each is the same, then each photon carries the same amount of energy. Three of them carry three times the energy that one of them carries.
What is a simple definition of Einstein's quantum theory of light?
Light comes in discrete packets called photons. Each photon has energy E = h*frequency. h is called Planck's constant and is ~6.626e-34 Js
