False. I think the other gave a good reason why.True or false?different electromagnetic waves travel through vacuum at different speeds?
False. From the longest waves which is just above DC to daylight and above all travel at the speed of light in a vacuum which is 186,000 miles per second.
False. They're all made of photons, regardless of the frequency. Photons always move at the speed of light.
