The speed of light, or c, is a constant. The speed of light is exactly 299,792,458 meters per second IN A VACUUM. That's 670,616,629.2 miles per hour or 983,571,056 feet per second.

Why is the statement speed of light is 300 million miles per second is not always correct?
First of all it's 300 million metres per second (299,792,458 m/s). this is in a vacuum when the speed of electromagnetic radiation is at its greatest.
Explain why the statement the speed of light is 3 million MS is not always correct?
I'm going to remark that "The speed of light is 3 million meters per second" is NEVER correct. The speed of light in vacuum ... within 0.07% ... is 3 hundredmillion meters per second. The speed is different in any material medium, but a speed of 3 million m/s would imply a medium with a refractive index of 100, and I'm pretty sure that no such material exists.
When you turn on a light or other electric appliance you close a circuit?
This statement is correct.
What is the correct abbreviation for light-year?
The correct abbreviation is LY.- A kilo light-year is KLY.(1,000 light-years).- A mega light-year MLY.(1 million light-years).- A giga light-year is GLY.(1 billion light-years).
How many light years in a mega light year?
Wherever "mega" is use in physics, it always means "million".
Will the check engine light ALWAYS come on if the oxygen sensor is bad?
No not always,But it will correct problem 99% of the time. Brett
How far is the Sun from Earth if it takes a minute for the Sun's light to reach Earth?
That statement is not true. It takes light about 8 minutes to get here from the Sun. The distance is 8 light minutes or 93 million miles.
Why is the statement the speed of light is 300 milllon miles per sec not always correct?
The speed of light, which is about 300,000,000 m/s, can be affected by the material that it is travelling through. Mediums such as air, glass, and water can slow light down. For example, in water, light travels at a speed of about 200,249,000m/s; in ammonia gas, it travels at 221,200,000m/s; and in ethanol, it travels 220,400,000m/s.
THE SUM OF the central angles of a circle depends on the measure of the radius?
Never. The radius of any central angle of one circle will ALWAYS be the same. And not only that ... To answer the question (or to correct the statement that was stated in the place where a question was to be expected): THE SUM of the central angles of a circle is always 360 degrees, whether the radius of the circle is 1 nanometer or 1 light-year.
How far is 36 light years into km?

What is a statement that is not true about a white light?
White light is monochromatic light.
During cold winter months the tire pressure monitoring light is always on how do you suspend it?
Make sure the tires have the correct pressure.
