Actually it is an interesting fact to be known thoroughly
Current through metal is due to the drift flow of electrons. Actually that drift velocity is just 0.1 mm /s
Very very slow.
But how does the bulb glow so immediately as switch on the circuit?
Here though electrons get drifted at such a low speed, that disturbance alone has been passed on from one region to the other at high speed. Hence we sense as if the current has passed at the speed of light. But acutally we cannot say that current flows at such a high speed.
What else can I help you with?
What light travels the fastest red or yellow?
they both travel at the same speed ? :>)
Is the speed of light greater or lesser in air than in water?
The speed is the same. Light travels at a finite speed.
Is the The speed of sound is the same the as speed of light yes or no?
No. Light travels much faster than sound.
What color travels the slowest?
All colors of light travel at the same speed in a vacuum, which is the speed of light. However, in mediums like air or water, the speed of light differs for different colors due to their different wavelengths and refractive indexes. Blue light generally travels slower than red light in these mediums.
Which color of light travels fastest through a telescope lens?
All colors of light travel at the same speed in a vacuum, including through a telescope lens. The speed of light is determined by the medium it travels through; in air or a lens, all colors of light travel at the same speed.
Is red light slower than blue light?
No. Light travels at the same speed, regardless of color.
Does light travels slowest through space?
As the medium through which light propagates in space is closes to a vacuum, light propagates very well in space. However, it travels at the same speed as it would on earth, as light travels at 299,792,458m/s in a vacuum, regardless of where that vacuum is located. the light travels in same speed whether it travels in space or earth.
What light travels the fastest in a vacuum ultraviolet or visible?
Light in a vacuum travels at the same speed regardless of its wavelength, known as the speed of light, which is approximately 299,792 kilometers per second. Both ultraviolet and visible light travel at this speed in a vacuum.
Is infrared light faster than microwave light?
Both infrared and microwave light travel at the speed of light in a vacuum, which is about 299,792 kilometers per second. Therefore, they both travel at the same speed.
How does the speed of a radio compare to the speed of visible light?
Radio waves and light are the same exact physical phenomenon, and differ only in their wavelength (frequency). Their speeds are identical.
Can you see light when it's at high speed?
No, light itself always travels at the same speed, which is about 186,282 miles per second in a vacuum. However, we can observe the effects of light passing through different mediums or interacting with surfaces, such as reflection or refraction.
Does color of a laser affects the velocity of the light wave projected by a laser?
No. Light travels at the same speed no matter what.
