Radio and light waves are electromagnetic waves, sound waves are not.
When you listen to the radio, you are hearing sound, which has no resemblance to light, radio waves, or x-rays. However, the sounds you hear are created in the radio receiver, using information that was carried to your location by means of radio waves.
Light is an electromagnetic wave; and those are transverse. Sound is usually a longitudinal wave.
Sound.
Radio signals propagate faster than sound signals. Speed of light (radio) is about 186,000 mps Speed of sound is about 1100 fps (0.5 mps).
Radio waves are sound. Therefore, yes, by definition, they travel at the speed of sound.
Ocean, light, radio, sound..etc etc
speed of light
Sound waves require a medium, such as air, water, or solids, for transmission. Light, radio, and infrared waves can travel through a vacuum and do not require a medium for transmission.
The pitch of sound is most similar to the brightness of light. Just like brightness represents the intensity of light, pitch represents the perceived frequency of sound. A higher pitch corresponds to a higher frequency, similar to how brighter light appears more intense.
transverse; longitudinal.
Light isanalogous in many ways to sound and many of the equations used to describe sound also apply to light, but there are limitations. Sound waves don't really polarize the way light waves do for example. Light also displays some characteristics of particle behavior that contradict its wave behavior - again making it different from sound.
Different is the speed of propagation. Scroll down to related links and look at "Acoustic or sound waves in air - Radio and light waves in a vacuum".
