Which is true about the speed of radio waves compared to light waves? They are...

• less energy & frequency, but still the SAME speed as the speed of light (300,000,000 m/s)

• less energy & frequency, so LESS than the speed of light (300,000,000 m/s)

• smaller wavelength, so LESS than the speed of light (300,000,000 m/s)

• more energy & frequency, so MORE than the speed of light (300,000,000 m/s)
