You are gazing at the sky when suddenly you see something very odd...

Before you get a chance to run, you realize....

You've been abducted by aliens!

Click on ship to begin.

They find you fascinating and want to keep you forever as one of their own. Clearly, this is not an acceptable fate for you. Your mission is to get back to Earth!

Back

As you are taken farther from Earth, you realize, you MUST do whatever it takes to get back home. Click on Earth to begin your mission!

Back

I'm Ditto! I want to see you get safely home! Click me for help at anytime!

Click here to cautiously head to the the control room.

And shhh! Don't let the others know I'm helping you!

The aliens have locked you in their cargo bay. You need to figure out how to get out of here. Click on the PhET logo. Correct answers to the simulation questions will give you the code needed to open the door.

What causes the waves to form?

Potential energy from the string is converted to kinetic energy.

The wrench or metal rod moving up and down creates a disturbance in the string.

What is the difference between oscillate mode and pulse mode?

In pulse mode, the wave is continuous. In oscillate mode, only a single disturbance is created in the string.

In oscillate mode, the wave is continuously oscillating. In pulse mode, only a single disturbance is created in the string.

Describe the motion of the green beads as the waves travel.

The green beads travel with the wave from one end of the string to the other.

The green beads only move up and down, perpendicular (at 90 degree angle), to the direction the wave travels.

In Oscillate Mode: What happens to the distance between peaks (the wavelength) when the frequency is increased?

The distance between peaks (wavelength) increases as the frequency increases.

The distance between peaks (wavelength) decreases as the frequency increases.

In Oscillate Mode: How does increasing the amplitude affect the wave?

Increasing the amplitude increases the frequency of the wave.

Increasing the amplitude increases the distance the string moves up and down and increases the energy that is carried by the wave.

Map of Ship

AUTOPILOTON

You walk into the empty control room. Thankfully the aliens are all celebrating your capture in a different room and have the ship on autopilot. You notice a screen labeled "Map of Ship." Perhaps seeing the map can be useful to you!

Access to the map will only be granted to those who can answer the following questions.

Wavelength- the distance between successive troughs, crests, or identical parts of a wave.

Frequency

Back

I frequently wish I could live on Earth.

Frequency is a measure of how many waves pass a point in a certain amount of time.

One peak passes by the red dot per second. This measurement is the wave's frequency! The units are cycles per second, which is the same thing as Hertz.

Lower Frequency Longer Wavelength Carries Less Energy Higher Frequency Shorter Wavelength Carries More Energy

This wave's frequency = 1 cycle/second = 1 Hertz

Earthling, I can tell you have grit! Keep working hard!

Review frequency and try again!
