1. The elasticity of an object changes the amplitude of a sound wave needed to break the object.
2. As waves travel further away from the source, they spread out. The amplitude of the wave is less because the energy spreads out.

# data[].attributes.body
1. Light always finds the shortest path
2.Things appear backwards in the mirror because we are the ones flipping the object.

# data[].attributes.body
1. Light always takes the shortest pathway, even if it's not straight.
2. Mirrors only show what we present to them.

# data[].attributes.body
1. When light photons pass into a new material and when their speed changes, their path gets changed. That's why things look distorted in arrows.
2. Things are flipped in a mirror because of the z flip, or a horizontal flip. Example: When you put on a shirt, the letters flip because you turn them away from you when you put them on and then the horizontal flip from the mirror too show them flipped.

# data[].attributes.body
1. Things are flipped in a mirror because that is the way we are presenting them to the mirror.
2. The glass beaker breaks when you hold the right pitch until it breaks.

# data[].attributes.body
1. The speed that light waves travel changes when the waves go through a different medium.

# data[].attributes.body
1. Light takes the fastest path it can between two places
2. Mirrors would flip the thing that you are pointing towards it,

# data[].attributes.body
1. The first video talked about putting an object in water and showing how refraction worked.
2. The second video shows and explains how reflection works with mirrors.

# data[].attributes.body
1.Light is faster in air than water

# data[].attributes.body
1.  When light travels through different mediums, it's speed differs.
2. Light takes the fastest path that it can take.

# data[].attributes.body
When the sound reaches the glass or a different matter then it will create frequencies and will change.

# data[].attributes.body
1. light travels faster in air then in water
2. once glass meets its oscillation capacity it breaks

# data[].attributes.body
1.  Two waves can cross through each other and create a larger wave
2. Two waves combining from crest to trough the wave cancels out.

# data[].attributes.body
1. It talks about when you put the straw in the water it looks like its bent.

# data[].attributes.body
1. Light takes the fastest path it can between two places
2. Mirrors would flip the thing that you are pointing towards it,

# data[].attributes.body
. Scientists discovered that rogue waves were more common than they thought.

# data[].attributes.body
1.) Sound waves are strong enough to break glass
2.) Light is the shortest amount of distance

# data[].attributes.body
1. As light travels through different mediums, its speed changes at the point where it meets.
2. When light travels to a different medium, not only does its speed change, but its path too. That's why we see the straw as dislocated or non-straight.

# data[].attributes.body
1. When more than two waves combined they get bigger then 100m in the open ocean.
2. When a wave and a trough combine the wave cancels out.

# data[].attributes.body
1.) When you put an object in water, their is a different speed that the object travels in for the water medium compared to the air. This makes the object appear broken.
2.) As a sound wave gains amplitude, it becomes strong enough to break a glass beaker.

# data[].attributes.body
1. Submerging in object in water causes the object to stray from its natural appearance. This is due to refraction.
2. Light is pretty quick.

# data[].attributes.body
1) Light travels slower through water.
2)When multiple waves meet at the right time, they make a monster wave.

# data[].attributes.body
1.) All light travels at the same speed
2.) Light speed can change

# data[].attributes.body
1.

# data[].attributes.body
When an object is put in water, it could look different or broken
because of light refraction

# data[].attributes.body
1. Light will always take the shortest distance between 2 places.
2. Light speed changes depending on the medium

# data[].attributes.body
1. Light takes the fastest path it can between two places
2. Mirrors appear horizontal and flipped because they are just presenting what you put in front of them back to you.

# data[].attributes.body
faster in air and water so when the straw is put in water and the other part is out of the water it looks broken from the side because the waves are moving faster Violet Erickson
