Slide 7, when and where?
When was this technology created?
In 1956.
What is the main thing Ultrasounds are used for?
Taking pictures of babies in women's stomachs.
What type of wave is used?
Sound waves. Also acceptable answers: compressional waves or ultrasonic sound waves
What is a medium?
Something a wave passes through
How would life be different without this technology?
It would be harder to find out the gender, any problems, how many babies are in the stomach, and more.
Where was this technology made?
Glasgow, Scotland.
What can Ultrasounds help to find in babies?
The baby's progress in growing, anything not normal, if kidneys are missing, disease signs, spinal issues, or any problems in general.
What spectrum are sound waves on?
The sound spectrum.
What is amplitude?
The height of the wave
Why can't we see sound waves?
Their medium (air/water) is invisible so most of the time we can't see the waves. A bell ringing is a time where we CAN see the waves.
Who were the 2 people who made this technology?
Ian Donald and Tom Brown.
What can Ultrasounds confirm?
A pregnancy.
How does matter affect it when the sound waves and matter interact?
The matter makes the echoes and vibrations in the stomach which show if there is a baby in there or not.
What is frequency?
The number of waves that pass a point in a certain amount of time
Is this the best type of wave for ultrasounds? Why or why not?
Yes, because there is no radiation and it gets the job done in a fast, easy, safe way.
What did Ian Donald and Tom Brown base this technology off of?
An instrument used to find flaws in ships.
TRUE OR FALSE:
Ultrasounds can find out how many babies are in the women and the gender of the babies.
TRUE
How are sound waves made?
Sound waves are made from vibrations.
What is wavelength?
The distance from the top of the wave to the bottom of the wave.
TRUE OR FALSE:
The echoes that bounce back are because of light waves.
FALSE the echoes that bounce back are because of SOUND WAVES
Why are sound waves not on the EM spectrum?
They are not on the spectrum because they need a medium like air or water.
What is a compressional wave?
A sound wave that vibrates and is a disturbance.
