Gizmo Ripple Tank Answer Key

Educatee Exploration: Ripple Tank

Directions: Follow the instructions to go through the simulation. Reply to the questions and

prompts in the orange boxes.

Vocabulary: constructive interference, crest, destructive interference, diffraction, Huygens' Principle,

interference, police force of superposition, node, refraction, trough, wave, wavelength

Prior Noesis Questions (Do these Before using the Gizmo.)

i. The prototype below shows small ripples, or waves, moving through water in a pond. Highlight the

clarification below that you remember describes the move of a wave most accurately.

A. Each moving ridge consists of a set of water molecules moving

outward from the center.

B. When a wave passes, water molecules move up and

downwardly before returning to near their original position.

2. Waves have crests (high points) and troughs (depression points). The

wavelength of a wave is the altitude between adjacent crests (or

troughs). Label the crests, the trough, and the wavelength on the

prototype at left.

Gizmo Warm-up

A ripple tank, such as the ane shown in the Ripple Tank Gizmo, is a shallow

pan of water with a vibrating motor that produces waves. The tank is lit from

above so that the wave crests and troughs are visible. Ripple tanks are

peculiarly useful because many properties of water waves are shared by

other kinds of waves that are harder to come across.

Check that Open tank is selected and the Wavelength is

4.0 cm. Click Play ( ) and find. Click Intermission ( ) when the start moving ridge

reaches the right edge of the tank.

1. The lite regions represent troughs while the nighttime areas represent crests.

About how much simulation time does it take the wave to cantankerous the tank?

2. Click Reset ( ). Ready the Wavelength to xvi.0 cm, and click Play. Click Pause when the waves attain the

edge. How did increasing the wavelength affect the shape and speed of the waves?

The waves were wider and moved faster. Took 1.0 s
