Waves are measured in billionths of a meter

# data[].attributes.body
Waves echo off of objects and bounce back.

# data[].attributes.body
X-rays use very high energy so the image goes through your skin and you can see your bones.

# data[].attributes.body
that Sound waves can create images through sonar.

# data[].attributes.body
Waves are energy moving through something. Waves can be very big, such as earthquakes. and very small, such as sound waves.

# data[].attributes.body
Sonar is when sound pulses are emitted and bounce off objects underwater

# data[].attributes.body
waves travel and are compressed so that they are continuously moving. When a wave hits a solid medium then the wave bounces back.

# data[].attributes.body
when waves travel, they always come back in the same shape and form. This is what creates an echo outside.

# data[].attributes.body
Waves don't always move up and down, they go back and forth hitting each other and that the waves have different shapes

# data[].attributes.body
I learned that waves travel and bounce back.

# data[].attributes.body
X-rays use very high energy to the point where it goes through your skin so you can see bones.

# data[].attributes.body
I learned that laser waves are coherent. Coherent waves are when the wavelengths and troughs are the same.

# data[].attributes.body
The higher the frequency of the wave the shorter the wavelength and the lower the frequency the longer the wavelength

# data[].attributes.body
When you're communicating with someone from thousands of miles away the waves are bouncing off the atmosphere and coming back to the surface .

# data[].attributes.body
That an echo is just the sound wave bouncing back to you of a hard surface.

# data[].attributes.body
Waves are all similar in shape and pattern

# data[].attributes.body
A wave isn't just moved up and down it can be pushed together.

# data[].attributes.body
Waves can travel far, so far that an earthquake in North America could be felt in Africa.

# data[].attributes.body
Seismic Waves are waves that travel through the whole Earth.

# data[].attributes.body
earthquakes can be caused by wave that can bounce off earths surface or in earths surface

# data[].attributes.body
energy doesnt always travel in waves but it can get shorter and longer

# data[].attributes.body
I didn't know that when you yell the wave hits the wall and bounces back

# data[].attributes.body
When waves travel, they always bounce back.

# data[].attributes.body
on a short pipe you have short wave length and on a long pipe there are long wave lengths

# data[].attributes.body
X-rays are so powerful that they can penetrate skin and muscle

# data[].attributes.body
That all energy moves in waves

# data[].attributes.body
To communicate with someone of the radio thing, it bounces off the atmosphere to the surface

# data[].attributes.body
When two waves crash, it creates a pattern or a rainbow

# data[].attributes.body
When using a radio you can communicate with people around the world because waves bounce out against the atmosphere and back to Earth

# data[].attributes.body
When you are using a radio to communicate with someone in a different place the waves bounce off of the atmosphere and back to earth.

# data[].attributes.body
Can measure waves

# data[].attributes.body
When waves bounce back, they're reflected.

# data[].attributes.body
When you move the sling fast the wave length goes slower and that goes with everything and the opposite
