No picture but sound on Acoustic tv?
sound waves don't have enough room
In a television the what waves carry the picture while the what waves transmit the sound of the program?
LM is video (picture)CM is auto (sound)
Are tv sound and picture sent through FM waves?
Picture is AM, sound is AM or FM
What industrial applications have longitudinal waves?
Industries that have longitudinal waves are cell phones, radio stations, television stations, and other industries that use sound waves.
Do TVs have motors?
No, they do not. They are electronics that send sound and video across the air waves.
Is a electromagnetic waves a form of sound?
No. Electromagnetic waves are light waves that include gamma waves, x-rays, UV light, visible light, infrared light, microwaves, TV waves, and radio waves--basically any form of radiation.
What makes the tv work?
electro magnetic waves that turn into sound energy and changes info
Are television waves transverse waves?
Electromagnetic waves have a transverse component.
Radio waves carry what from a station to your home?
Radio = sound wave T.V. = light wave [and sound from the speakers <33] That is completely wrong. Radio and television signals are both sent by RADIO WAVES.
Are sound waves circular waves?
no, sound waves are not circular. the top of a wave is called a crest and the bottom of a wave is called a trough. they are virtical waves.how high they are (amplitude) shows the loudness of the wave.the higher they are the greater the amplitude.how many crests pass a point in a certain amount of time is called frequency.the greater the frequency the higher the pitch.the sound waves that they do on television are just to help you explain in more.
How will decreasing the amplitude of the sound waves from a TV affect its intensity?
Amplitude is intensity. It refers to the strength of a sound wave, which the human ear interprets as volume or loudness and if you decrease the amplitude you also decrease its intensity.
Do some TVs use radio waves?
TVs receiving broadcast programming do, they just use it to produce both picture and sound; instead of just sound as an ordinary radio does. TVs receiving cable programming don't. TVs receiving satellite programming do, but the radio waves are in the microwave band transmitted from the satellite and received by your dish, where they are down converted via a microwave superheterodyne stage in the dish so that they are in the frequency range the TV can handle.
