Short wavelengths and high frequency

Long wavelengths and high frequency

The injury was not committed using a slinky.

Long wavelengths and low frequency

Mrs. Fink was doing jumping jacks in the Exploratorium.

Short wavelengths and low frequency

Wavelength

A slinky was not found near the victim.

Medium

Mr. Bogdan was reading Tolkien in the Discovery Center.

The victim did not have a gamma radiation.

Amplitude

Frequency

CLUE #3

Which is true about light?

It speeds up steadily until the source becomes

A slinky was not used on the victim.

stationary then it slows down.

Ms. Benton was reenacting WWII in the Wing of Innovation.

It’s speed is constant if the source is stationary,

speeding up, or slowing down

It’s speed will speed up if the source is speeding up and slow down when the source slows

The victim did not have a gamma radiation.

It’s speed will slow down if the source is speeding up and go faster if the sources speeds up

Mrs. Unrath was making a volcano in the Gallery of Science.

CLUE #4

If a wave is traveling at a constant speed, and the frequency increases, what would happen to the wavelength?

It remains constant

Mr. Hinshaw was walking his snake in the Exploratorium.

It would increase

The victim’s did not succumb to x-rays.

It would decrease

The victim was not exposed to gamma rays.

It would stop moving

Dopper Effect

The Doppler effect is a change in the sound or light waves when the source of the waves is moving. It was discovered by a scientist named Christian Doppler in 1842. One example of the Doppler effect is when a vehicle with a siren approaches and then passes by. The sound of the siren sounds higher as it gets closer and lower as it moves away. When the source of the sound wave is moving towards you, the time between each wave is shorter, so the frequency is higher. But when the source is moving away from you, the time between each wave is longer, so the frequency is lower. This is because each wave is emitted from a position closer or farther from you than the previous wave . The Doppler effect is used in many different fields of science. Astronomers use it to detect planets outside of our solar system, called exoplanets. They can tell if a star is moving towards or away from us by looking at the changes in its spectrum, which is the colors of light it emits. By studying these changes, scientists can learn more about the planets and stars in our universe. So, the Doppler effect is a cool scientific discovery that helps us understand how sound and light waves change when the source is moving. It can be seen in everyday life, like when a siren gets louder and then quieter as a vehicle passes by. And it's also used by scientists to learn more about the stars and planets in our universe.

Light is a special kind of energy that travels in waves. It can travel through empty space, like in outer space. Light travels really, really fast - even faster than sound! In just one second, light can go around the Earth seven and a half times. That's super fast! When we see the Sun, we're actually seeing what it looked like over 8 minutes ago because that's how long it takes for light to reach us from the Sun. Light always moves in straight lines until it hits something. That's why shadows are formed when light is blocked by an object. Shadows don't look completely dark because some light still gets around the object. Light can also travel through different things, like air, glass, and even mirrors. When light passes through different materials, it can change direction, but it still moves in a straight line called a ray. Light can also behave like particles called photons. These particles are really tiny and they move really fast. Light can also spread out as it travels, which is called diffraction. This is why sometimes you see spikes of light attached to stars in pictures. Scientists are still learning a lot about light and how it works, but it's really amazing how it can travel so fast and in straight lines!
