Video transcript

Hey everyone, our question here states that radiation with longer wavelengths and radiation with smaller wavelengths in a vacuum, travel at the same speed is a statement true or false. This statement is going to be true, And the reason why is because in a vacuum our speed of light is always going to be 3.0 times 10 to the 8th m/s, regardless of the different wavelengths. So I hope this made sense and let us know if you have any questions.
