All waves on the electromagnetic spectrum travel at the same speed in a vacuum. the speed of these waves in a vacuum is 3x10 8 m/s. as the wavelength of a wave doubles, how does the speed and frequency of the wave change?

the real answer is A the speed remains the same and the frequency halved hope this helps

i think if it were me i whould divide 300 dide 15
