Why the intensity of the light in a flashlight beam decreases as the flashlight moves farther away?
Because the constant amount of light that the flashlight produces is spread out over a larger area when it's farther away, so the intensity at every point is less. Light decreases inversely to the square of the distance.
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.
Which wave property decreases as you get farther away from the source of a sound?
Intensity
Why is an energy pyramid shaped as a pyramid?
This is because the farther up you go in the energy pyramid the energy decreases.

What happens to the brightness of the star as you observe it from farther away?
The brightness of star will decrease as you observe it from farther away.
What happen to the brightness of a star as you observe it from farther away?
The brightness of star will decrease as you observe it from farther away.
According to the inverse square law of light how will the apparent brightness of an object change if its distance to us changes to one half as much as it was.?
If the brightness is 'B' right now, when the object is at a distance 'D' from your eye, then-- If the object moves closer, to only [ 1/2 D ] from you, the brightness increases to [ 4 B ].-- If the object moves farther away, to [ 2 D ] from you, the brightnesses decreases to [ 1/4 B ].

Why can a lazer light go farther than a flashlight?
Because The Miz said so.
