hello everyone.
I will be talking about what we have been doing in science and answering some question about communication in space. first I will be answering the question about communication in space.
1.what are tree ways we communication and how do they work
Some people use phone calls when you call your friends the phone converts
your voice into an electrical signal which gets transmitted via radio waves to the
nearest cell tower.
You can use a radio to communicate with people. It works by a transmitter sending and
getting electricity signals. The radio is sent outward by an antenna. a receiver then picks
up the signal and translates it to the sounds heard through the radio.
Tv can be used to communicate. The camera turns the sound and picture. The tv
transmitter that sends the signal through the air then the receiver in your tv at home picks it
up.
2.why cant you hear things in space
You can not hear in space because there is no air and your voice needs to vibration thowe
the air.
3.is radio communication instant why or why not
It will not be instant because they will be so far away that it will take some time to reach
the spacecraft. Radio waves are very fast but its not instant radio waves actually move at
the speed of light.
4.what does this mean if we where going to go to mars from earth.
his means if nasa is trying to communicate it will take awhile to get a respond from the
other guys.
and in sconce we had a challenge in the challenge we had to put a bucket over are
heads and a blind fold on and then we had to try to work straight and if we won we
got 5 buck and anyway until next time and I will make a blog on the challenge.
