# Do electromagnetic waves travel at the speed of sound?

Contents

Radio waves are electromagnetic waves and do not require a physical medium to travel (or propagate). So, like all EM waves, they travel at the speed of light, c. Sound waves are a type of matter wave in the sense they are compressions and rarefactions of the medium (solids, liquids, and gases) they travel in.

## Do electromagnetic waves travel at the speed of light?

Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum. … We call this the “speed of light”; nothing can move faster than the speed of light.

## Do electromagnetic waves travel faster than sound?

As such, they travel at the speed of light (ie 300,000 kilometres/186,000 miles per second) – a lot faster than the 340 metres (1,125 feet) per second that sound itself moves through the air.

## Do all types of electromagnetic waves travel at the speed of sound?

Unlike water waves, electromagnetic waves always travel at the same speed (3 hundred million metres per second) and sound waves all travel at the same speed in a given medium (for example, approximately 340 metres per second in air). The speed of a wave is related to both its frequency and wavelength.

## Can electromagnetic waves travel through sound?

There is no sound in space because there are no molecules there to transmit the sound waves. Electromagnetic waves are not like sound waves because they do not need molecules to travel. This means that electromagnetic waves can travel through air, solid objects and even space.

## Why do all sound waves travel at the same speed?

All sounds travel the same speed in the same medium because all the particles within that medium are the same or averagely the same distance and structure apart. For example, all molecules in water, are more or less, the same distance apart.

## At what speed does electromagnetic travel?

Electromagnetic radiation is an electric and magnetic disturbance traveling through space at the speed of light (2.998 × 108 m/s).
