What does the speed of light equal in a vacuum?
The speed of light is a constant, C= 300,000 km per second.
Can the speed of light be changed?
no. speed of light is always constant . as long as the light stays in the same medium. the speed is generally slightly different in different media.
Which variable is used to represent the speed of light?
None. The speed of light is usually assumed to be constant. The symbol used to represent the speed of light is "C", as in E=MC2. Then why is it called a variable speed?
What is the average constant speed of light in vacuum?
The speed of light in vacuum is 299,792,458 meters per second, and that's not an average. That's what it always is.
How do determine planck's constant?
Energy/frequency or energy*wavelength/speed of light.
Why constant is used?
Constant is the speed of light and as the speed of light cannot change it is 'constant'
Why use constants?
Constant is the speed of light and as the speed of light cannot change it is 'constant'
What does special relativity say about the speed of light?
The speed of light is constant.
Can light exceed its normal speed?
The speed of light is constant and can not be changed
What is speed that does not change - called?
constant
What is the constant speed at which light and other forms of radiation travel?
The constant speed at which light travels is 300M m/s.
Is the speed of light a constant?
Yes
Is speed of light constant?
yes
Which of these is constant for ALL types of electromagnetic radiation in a vacuum?
Answer = Velocity Velocity is the speed of light and, the speed of light, is a constant among Electromagnetic Radiation in the vacuum of space.
Is the speed of light constant in a vacuum?
Yes
Does planck's constant stand for speed of light?
No, it does not.
What happen when speed of light is not constant?
It is impossible that a constant thing can become inconstant..... \
