What is the output in the system of a flashlight?
The output of a flashlight is its light
How energy is transformed light from flashlight?
Battery electric energy is converted to light energy of flashlight.
How are electromagnetic waves used in a flashlight?
The light produced by a flashlight is electromagnetic radiation.
Why does the brightness of the light emitted by a flashlight decrease as the flashlight moves farther away from you?
Because the constant amount of light that the flashlight produces is spread outover a larger area when it's farther away, so the intensity at every point is less. The flashlight might attack you, so be careful. Also, if your earlobes are out of control, tape them down. Please.The torch light penetrate each so much light is not parallel, with the light propagation distance become far, spacing between the light light is more and more big, making smaller according to the density of light in the distance.
How is laser light different from light emitted from a flashlight?
Laser light is different in many ways. These are the biggies. a) Laser light is almost monochromatic. Because it is created by exciting a specific substance to emit photons, the light emitted by the source is almost all one specific wavelength. The light from a flashlight contains all of the colors in the spectrum, forming "white light". b) Laser light is very coherent. This means that the waves leaving the laser remain in phase for a very long time. Light from a flashlight is not coherent. As a result, a laser can project a distinct beam of light much farther than a flashlight. c) Laser light is directional. This means that the beam of light being emitted does not spread much with distance. Hence it can still appear as a point of light many meters away from the source. A flashlight beam will quickly spread the further it is viewed from the source. Because of these fundamental properties, lasers are an excellent experimental device.
If you hold a flashlight at the speed of light can you still see it?
Need clarification please. The "it" you are referring to seeing, does that represent; A) the flashlight, B) the light from the flashlight, or C) "the speed of light"? Did you mean to imply that the flashlight was switched on? Is it an "old fashioned" bulb, an LED bulb, a laser light, or some other energy? Just wondering.
What are the disadvantages of a flashlight?
battery will eventually run outtakes one hand to hold itlimited light output.
How does the moon get its own light?
If you took a round object liken unto a basketball and sat in a dark room, would the basketball give out light. correct. the answer is no. If you took the same basketball and sat in a room and held a flashlight under the basketball, would the basketball give out light on the other side. correct. the answer is no. now, if you took the flashlight and held it above the basketball approxmiately 6 inches above, does the basketball now have light. and the farther away you hold the flashlight above the basketball the more light will shine upon the flashlight. Question. Where did the flashlight get its light from. correct. the flashlight. the moon gets it light from the sun. The moon reflects the light that is provided from the sun and the basketball reflects the light that is provided from the flashlight.
Which is the brighter - the light coming in or the light from the flashlight?
Sun light is more brighter than the light from flashlight in house.
Which is brighter the light coming from in or the light from the flashlight?
Sun light is more brighter than the light from flashlight in house.
Is a flashlight is a output?
A flashlight outputs light and heat.
What is the output in the system of a flashlight?
The output of a flashlight is its light
What is an output in a flashlight?
A flashlight outputs light and heat.
Does a light switch change chemical energy directly in to light energy or does a flashlight?
The flashlight does.
How much does a flash light weigh?
Designed to be portable, many varieties of flashlight exist.
How energy is transformed light from flashlight?
Battery electric energy is converted to light energy of flashlight.
Is a flashlight good model for suns light energy hit earth?
Flashlight is not good model to test sun light hit earth. The light of flashlight is too small energy to compare sun light.
