it moves slower because of sudden movement
They can ONLY move slower than the speed of light.
Light travels through water at a speed of about 225,000 kilometers per second, which is approximately 25% slower than its speed in a vacuum.
No but the leader that travels from the cloud to the ground travels at about 60 000 m/s. Light travels at 300 000 000 m/s. Note that the bright flash of lightning occurs on the return stoke and travels from the ground up to the cloud. Read the article on lightning at Wikipedia.org, 'The World's Encyclopedia'. The link is in the related links below.
Light travels faster in air than in water because the density of air is lower than that of water. Light changes speed and direction when it enters a different medium due to the change in density, causing it to move slower in water.
The electrical current (or signal) travels at about 2/3 the speed of light in a vacuum - that is, it travels at approximately 200,000 km/sec. Note that individual electrons move slower than that.
A photon travels fastest through a medium, followed by sound, then electrons. Photons travel at the speed of light in a vacuum, which is faster than the speed of sound or electrons in a medium. Sound travels at a much slower speed than light, while electrons generally move at speeds that are significantly slower than both photons and sound waves.
No, because the orbital is really just an abraction - the electron isn't racing around the orbital like a racecar, so there isn't a speed. The orbital is a better measure of the electrons potential energy.
Light travels through water by penetrating the water molecules and being absorbed and scattered as it passes through. The speed of light in water is slower than in a vacuum, causing refraction that changes the light's direction. Overall, light can travel through water but may be attenuated depending on the water's clarity and the distance it travels.
Both light and sound travel. Light travels the fastest.
Light energy travels in the form of electromagnetic waves, which do not require a medium to propagate. These waves consist of oscillating electric and magnetic fields that move through space at the speed of light.
Light travels at a speed of about 186,282 miles per second in a vacuum.
No. Because of their mass, they travel slower than c.
