How do air molecules enable sound to travel from a radio speaker to your ear?

∙ 12y ago
Sounds waves are compressional, and compressional waves are made up of compressions and rarefactions. When the radio speaker pumps sound outward, it forms a compression by pushing the molecules in air together. The compression moves away from the speaker as these molecules collide with other molecules in air. When the sound travels back, a rarefaction is formed where the molecules are farther apart. The air molecules form compressions and rarefactions. Compressions and rarefactions make up compressional waves. A sound wave is a compressional wave.

∙ 11y agouse air as their medium of propagation i think by vibrational movement of the air molecules because sounds moves as waves

What is the energy transformation in a speaker connected to a radio?
Electrical energy is used to vibrate a diaphragm. The mechanical energy so produced vibrates the air molecules in contact with the diaphragm and these vibrations are then propagated as sound.

Why radio waves travel longer over the sea?
Radio wave strength can be affected by weather when traveling over the sea. Unusual atmospheric phenomena enable longer radio wave travel.
