Directions: Look at the picture and read the information below and then answer questions 1-5. The questions should be completed in order. Each new question will build on your response from the previous one.
Scientists use sonar (sound waves) to help them study parts of the ocean that are difficult to see. The picture to the left shows how an ancient shipwreck found on the ocean floor can be mapped out using only sound waves!
These sounds can be harmful to marine animals, such as whales and dolphins. A group of scientists would like to test if lower amplitude waves or lower frequency waves are safer for animals.
You are part of a team that has been asked to create several different sound waves to test in the ocean.
Draw a model of the original sonar wave the scientists are currently using. The wave has a(n):
Wavelength of 8 units
Amplitude of 2 units
Draw two (2) wavelengths of the sound wave
Create a wave with a lower amplitude than the original wave. (The wave you drew in Question 1 is the original wave.)
Describe how the new wave you created in question 2 will sound different from the original wave.
Create a wave with a lower frequency than the original wave. (The wave you drew in Question 1 is the original wave.)
Describe how the new wave you created in question 4 will sound different from the original wave.
Directions: Read the information below and then answer question 6-8.
Another scientist is exploring the caves in southern Arizona. He came across a cave with an underground lake inside. He decided to see how different kinds of waves would interact with the environment in the cave. Help him figure out what happened with light waves.
The scientist decided to test how light waves would look on the cave walls. He takes out his flashlight and shines the beam towards the top of the cave. Part of the light hits the black cave wall and seems to disappear into the rock. Another part hits a mineral stuck in the wall. He sees a shine reflecting back onto the flashlight, and a rainbow of light on the wall next to the mineral.
Draw the light wave hitting the object and then draw the path of the light wave after it hits each material.
Light wave hitting the black cave wall
Draw the light wave hitting the object and then draw the path of the light wave after it hits each material.
Light wave hitting the mineral, which shines the light back to the flashlight
Draw the light wave hitting the object and then draw the path of the light wave after it hits each material.
Light wave hitting the mineral, and a rainbow appears

Directions: Look at the following models of two different light waves.
Write two statements comparing the color and brightness of the two waves.
Color -
Brightness -
