___ can convert sound waves to an electrical signal that can be converted to radio waves, microwaves, or light waves. Receiver convert the tramsmission back into electric signal, and the speaker changes the electric signal into a ___ wave
microphones....sound
The missing word in the first part of the sentence is "microphone," which can convert sound waves to an electrical signal. The missing word in the second part of the sentence is "sound" wave, as the speaker changes the electric signal back into sound waves.
To get the answer, you can start by understanding the basic components and process involved in transmitting and receiving sound waves. A microphone is a device that converts sound waves into an electrical signal. This conversion is achieved through the use of a diaphragm, which vibrates in response to sound waves and generates an electrical voltage proportional to the sound wave's intensity. This electrical signal can then be further processed or transmitted.
To convert this electrical signal into radio waves, microwaves, or light waves, an additional device called a transducer is required. A transducer converts one form of energy into another form. In this case, the electrical signal generated by the microphone is converted into the desired form of energy (radio waves, microwaves, or light waves) using specific electronic circuitry and mechanisms.
On the receiving end, a receiver device is used to capture these transmitted waves (radio waves, microwaves, or light waves) and convert them back into an electrical signal. This process is achieved through the use of specialized antennas, detectors, and demodulation circuits, depending on the type of waves being received.
Finally, the electrical signal produced by the receiver is sent to a speaker, which is designed to convert this electrical signal back into sound waves. A speaker consists of a vibrating diaphragm that responds to the electrical signal, creating corresponding air pressure variations that result in the production of sound waves.
Therefore, with the help of a microphone to convert sound waves into an electrical signal, a transducer to convert the electrical signal into radio waves, microwaves, or light waves, a receiver to capture and decode these transmitted waves back into an electrical signal, and a speaker to convert the electrical signal back into sound waves, the entire process of converting sound waves to different wave forms and vice versa can be achieved.
