The answer is A and B or as you answered C. Light waves are faster and have a smaller wavelength than radio waves. Your teacher is wrong!

The speed is the same, the wavelength is different. Radio waves are larger than light waves.

Wavelength. It is at the beginning of the spectrum, light in the middle. All electromagnetic waves travel the same speed.

Radio Wave is a light wave. It’s just at a non-visible wavelength, so B. They both travel at the speed of light. I see *way* too many people thinking that radio waves travel at the speed of sound, because it carries music.

The answer could either be B or D. It depends on how you define light. If you define light as an electromagnetic wave then it is D. In that case radio waves could be defined as light because radio waves are electromagnetic waves with a low frequency and high wavelength . If you mean visible light then the answer is B because all electromagnetic waves move at the same speed they just have differing wavelengths and frequencies. http://cache.eb.com/eb/image?id=73584&re…
