Can you start a sentence with a sound?
Sound waves travel through the air to my radio.
Why can radio waves travel through space but sound waves can not?
Radio waves travel through empty space because they are electromagnetic waves, whereas sound is a wave that must travel through air.
Why is radio used on moon to communicate?
There is no air and sound waves do not propagate through vacuum.
The moon blocks radio signals sent from earth?
no You can even listen to the radio on earth. But there is no air to hear the music their though. (Sounds are passed through the air in sound waves)
How was thermal energy tranferred to the kitchen?
by the air
Why do astronauts use radio waves instead of sound waves to communicate in space?
sound needs something to travel through and space has no air for it to travel
Why do astronauts who land on moon talk through wireless sets using radio waves?
Sound needs air to travel through, and as there's no air on the moon. Astronauts have to use radios to talk to each other when in an envrionment without air. Radio waves travel through space and have no trouble traveling where there's no air.
Why can't we communicate in outer space?
We can if we use radio. Without it, sound waves can't travel through space because there is no air for it to travel through.
Which gases does sound travel through?
Sound can travel as long as there is something for it to travel through. This could be a gas (such as air), a liquid (such as water) or a solid (such as a metal). In outer space there is no air for the sound to travel though, so astronauts can not talk with each other unless they use a radio. Radio waves and light waves can travel through space, that is why we are able to receive light from the sun. Source: www.examville.com
Can sound travel through air and evidence?
Sound travels through air. Experiment: Listen. Result: Do you hear anything? That sound has traveled through air.
How does sound interact when it hits an object?
One thing we need to know is sound can get transferred only when it hits a medium(like air). The way it travels is by transfering the energy from one particle to the next and so on The sound wave has energy which it would transfer to the object. some part of this energy is tranferred through the object. Some is scattered in all directions
Why person heard the message through the cell phone before they heard it through the air?
Radio waves move at the speed of light, much faster than the speed of sound.
