Question

18 after careful analysis, an electromagnetic wave is found to have a frequency of 7.8 x 10^6 hz. what is the speed of the wave? * (0.5 points) 2.34 x 10^15 m/s 3.00 x 10^8 m/s 1.18 x 10^40 m/s 5.17 x 10^-27 m/s 8.49 x 10^-41 m/s 3.85 x 10^1 m/s

Explanation:

Step1: Recall wave - speed formula

All electromagnetic waves travel at the speed of light in a vacuum. The speed of light \(c\) is a constant value.

Step2: State the speed of light

The speed of light (speed of electromagnetic waves in a vacuum) is \(c = 3.00\times10^{8}\frac{m}{s}\).

Answer:

\(3.00\times 10^{8}\frac{m}{s}\)
