speedMPH= (2.998 x 108x 1/1000 x 0.621 x 60 x 60) miles/hr speedMPH= 6.702 x 108miles/hr Answer The speed of light in miles per hour is 6.702 x 108miles/hr.
To make measurements familiar to people in different countries (e.g. USA uses miles for most purposes whereas other countries use meters or kilometers), it may be necessary to convert the units of a quantity such as the speed of light.Answer and Explanation: The speed of light in m/s is...
What is the speed of light in a vacuum? A. About 300,000 kilometers per second. B. About 186,000 miles per hour. C. About 670 million miles per hour. D. About 1,080 million kilometers per hour. 相关知识点: 试题来源: 解析 A。在真空中,光的速度约为 300,000 千米每秒,A 选项...
How fast is the speed of light in miles? The speed of light in a vacuum is 299,792 kilometers per second, which translates to 186,282 miles per second. Hypothetically, this means that if an object could travel at the speed of light, it could go around the Earth 7.5 times in one se...

How many meters does light travel in a second? The speed of light is 3.00 x 10^8 m/s. How fast is this in miles per hour (miles/h)? What is the speed of light measured in? What is the speed of light squared? What if the speed of light was not constant?
Is the speed of light constant? The speed of light is a universal constant in a vacuum, like the vacuum of space. However, light *can* slow down slightly when it passes through an absorbing medium, like water (225,000 kilometers per second = 140,000 miles per second) or glass (200,...
So the speed of light is more of a universal speed limit than an absolute rule for how fast photons travel, the new data suggest. Miles Padgett led the new study. As an optical physicist, he works at the University of Glasgow in Scotland. He and his colleagues showed that the key to ...
The speed of light in MPH is 670,616,629 mph, 299,792,458 meters per second, or 186, 282 miles per second. Light takes approximately one second to travel the 238,854 miles to the moon. The speed of light is considered a physical constant that is used in many areas of physics. This...
Einstein's theory of special relativity tells us the speed of light is 186,000 miles per second (300 million meters per second). (Image credit: Iscatel | Shutterstock) Paul M. Sutter is an astrophysicist at SUNY Stony Brook and the Flatiron Institute, host of Ask a Spaceman and Space...
