Question

what is the speed of a photon with a frequency of 5x10^14hz

o 10.0x10^8m/s

o 1.5x10^8m/s

o 3.0x10^8m/s

o 33.0x10^8m/s

Explanation:

Step1: Recall photon speed property

The speed of a photon in a vacuum is a constant, known as the speed - of - light.
The speed of light $c = 3.0\times10^{8}\text{ m/s}$, regardless of its frequency.

Answer:

C. $3.0\times10^{8}\text{ m/s}$
