Question
Given the following medium parameters εr = 1, σ = 0, μr = 1Find the speed of electromagnetic wave.
Solution 1
To find the speed of an electromagnetic wave in a medium, we can use the formula:
v = 1 / √(εr * μr)
Given that εr = 1 and μr = 1, we can substitute these values into the formula:
v = 1 / √(1 * 1)
Simplifying the expression:
v = 1 / √1
Since the square root of 1 is 1, we have:
v = 1 / 1
Therefore, the speed of the electromagnetic wave in this medium is 1.
Solution 2
To find the speed of an electromagnetic wave in a medium, we can use the formula:
v = 1 / √(εr * μr)
Given that εr = 1 and μr = 1, we can substitute these values into the formula:
v = 1 / √(1 * 1)
Simplifying the expression:
v = 1 / √1
Since the square root of 1 is 1, we have:
v = 1 / 1
Therefore, the speed of the electromagnetic wave in this medium is 1.
