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.
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
What do mechanical waves need to travel?
Matter! Watching a wave travel through water is mechanical waves. Putting your ear to train tracks, and hearing the train, and feeling the vibration is a mechanical wave. Same with hearing someone talk!
How far away can an elephant talk with other elephants?
A surprisingly long distance as elephants are able to generate very low frequency sounds (i.e. infrasonic, frequencies that humans cannot hear at all) that can travel through the ground for many tens of miles and still be heard by other elephants.
How could Neil Armstrong talk to Nixon through the vacuum of space?
The communication was done using radio signals which can be transmitted in a vacuum. Radio waves are part of the electromagnetic spectrum, as are light waves, x-rays and microwaves. Just as light from far distance stars travel through empty space and reach your eyes, so can radio waves travel through space to a radio receiver.
Can elephants talk to each other by making sounds called tummy rumbles?
Elephants have a wide variety of noises, including trumpeting with their trunks, but also make low rumbling sounds with their vocal cords (not their "tummy") that are subsonic and can travel for miles through the ground (they're seismic"). The sounds can be heard by other, distant, elephants through their feet and trunks. These low frequency noises are called 'infrasound'.
Can an explosion be heard on the surface of the moon?
Sound can travel in the solid rocks of the moon but sound can not travel on the surface of the moon because there is no air for the sound to travel in.
Is it possible for an electromagnetic wave to pass through a vacuum?
No. Electromagnet waves can penetrate and move through, many substances, depending on frequency and power.If it only travelled through a vacuum, we wouldn't have, TV, Radio, mobile phones, radar or microwave ovens.
Is there another way of communicating then electromagnetic energy?
Yes. For example, if we talk, we use sound waves. Other ways of communicating are through electrical signals (currents that travel through cables); by sending letters, as well as a few other options.
When two men talk on the moon they cannot hear each other why?
Sound waves travel via vibrating molecules in air or other materials (water for example). On the Moon there is no atmosphere and as such nothing for sound waves to travel in.
What is it called when waves travel as a group?
When waves act together, you talk about "interference".When they reinforce each other, it is "constructive interference".When they cancel each other, it is "destructive interference".
When was Elephants Only Talk Occasionally created?
