Question
The velocity of electromagnetic wave in free space is given by
Solution
The velocity of electromagnetic wave in free space is given by the equation:
v = c
where v represents the velocity of the electromagnetic wave and c represents the speed of light in a vacuum.
Step 1: Identify the equation for the velocity of electromagnetic wave in free space.
The equation is v = c.
Step 2: Understand the variables in the equation.
The variable v represents the velocity of the electromagnetic wave.
The variable c represents the speed of light in a vacuum.
Step 3: Substitute the values of the variables.
Since we are considering the velocity of electromagnetic wave in free space, the speed of light in a vacuum is used. The speed of light in a vacuum is approximately 299,792,458 meters per second.
So, v = 299,792,458 meters per second.
Step 4: Simplify the equation.
The equation v = c remains the same.
Step 5: State the final answer.
The velocity of electromagnetic wave in free space is approximately 299,792,458 meters per second.
