Multiple choice physics electromagnetic waves properties and uses of different radiation electromagnetic spectrum spectrum

Astronauts communicate with one another on moon with the help of.

  1. radio waves

  2. sound waves

  3. ultrasound waves

  4. infrasound waves
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Answer is A.

Astronauts communicate with each other in space when they are spacewalking through the use of radio waves. Radio wave signal are sent to their headsets which then translates the signal into the form of sound . When receiving and sending message to earth it is sent in the form of radio waves which is then translated to sound wave (message) by a radio set.
