Radio waves are electromagnetic radiation.
The decoder seperates the sound wave from the rest of the radio wave.
A radio wave travels about 874,000 times as fast as a sound wave,plus it doesn't need any material to move through, as sound does.
Properties of radio wave ar: sound, uses of antenna, hz.
Sound.
ultrasonic wave is sound frequency
Sound isn't. The others are.
Light is an electromagnetic wave; and those are transverse. Sound is usually a longitudinal wave.
Radio wave is not an example of a mechanical wave because it is an example of an electromagnetic wave. Mechanical waves require a medium to propagate, while electromagnetic waves can travel through a vacuum.
They're very different. A sound wave is a longitudinal wave and a radio wave is a transverse wave, radio waves are in the same family as light because they're electromagnetic waves whereas sound waves are just caused by particles passing on a vibration.
Radio wave travel faster than sound wave. Radio wave is the same as light wave except at different wavelength. It travel at speed of light (3 x 108 m/s). Sound wave travel at only 330 m/s and probably can go up to 3,300 m/s in solid medium which is far slower than the speed of light.
In a radio, electrical energy from the batteries or outlet is converted into electromagnetic waves by the transmitter. These waves travel to the receiver where they are converted back into electrical signals, which are then converted into sound waves that we hear through the speaker.
Sound wave A sound wave needs something to allow it to spread. Air, water, solids etc. This is known as a 'medium' and sound waves need a medium in order to propagate. These waves are known as 'longitudinal' waves. Analogy This is similar to a line of traffic being hit by a fast moving truck failing to stop. The resulting wave of collisions move. through the line until t reaches the first car. Sound waves cannot travel through a vacuum such as in space and many Hollywood movies make this mistake. Radio Waves These can travel through the air or the vacuum of space so they do not need a medium. They are generally transverse waves like ripples on a pond radiating from the transmitter
