Top best answers to the question «Where can light travel but not sound»

But unlike sound waves or water waves, it does not need any matter or material to carry its energy along. This means that light can travel through a vacuum? a completely airless space. (Sound, on the other hand, must travel through a solid, a liquid, or a gas.)

Light can travel in a vacuum because light waves are electromagnetic in nature, which sound waves are not. Sound waves require a medium to travel. The speed of sound is faster in solid materials, slower in liquids, and slowest in gases. The speed of light in a vacuum
speed of light in a vacuum
The speed of light in vacuum, commonly denoted c, is a universal physical constant that is important in many areas of physics. Its exact value is defined as 299792458 metres per second (approximately 300000 km/s or 186000 mi/s).

is commonly given the symbol c.

In a vacuum. Light can travel through outer space (Moon to Earth), but sound cannot because sound requires air to transmit the vibrations that we recognize as sounds.
