You are on a team that is developing a game about people in outer space. You are using a computer program to create the sounds that will be used in the game. To make the sounds on your computer you have to change the characteristics of sound waves.

Graph 1 shows a sound (one note) you are working on.


1.

One way you can change the sound is to increase or decrease its frequency.

Which of the graphs below shows how Graph 1 would change if you increased only the frequency of the wave? Graph _______.


The following graphs (Graph 1 and Graph 2) show two different graphs for the same note.

2.

When the computer program plays the sound wave shown in Graph1, how do you think it will be different from the sound made with Graph 2? Use evidence from the graphs and what you know about waves (wavelength and amplitude) to support your claim.
CFS:
  • Accurately identifies the differences in wave outcomes
  • Accurately describes the relationship between wave properties and outcomes
"I think Graph 1 will sound different than Graph by ..."

(hint. Look at wavelength and amplitude)

3.

Your friend says that she heard about a special type of ink that is only visible when it is out in the sun. What type of light interaction allows for objects to change?

"I think the only type of light interaction that can cause a change is..."

4.

Can light from the sun cause this ink to become visible?

5.

Omar has a piece of rock called quartz. He wonders whether light can cause the quartz to become warm. The table below shows what happens when different types of light hit the quartz.


Based on this information, which type of light is more likely to cause the quartz to become warm?

6.

Which wave(s) are different types of light? What evidence do you have?


CFS:
  • Accurately identifies the differences in wave outcomes
  • Accurately describes the relationship between wave properties and outcomes
I think wave(s) ___ are different because ..."

(hint. Look at wavelength and amplitude)

7.

Which wave(s) are the most intense? What evidence do you have?
CFS:
  • Accurately identifies the differences in wave outcomes
  • Accurately describes the relationship between wave properties and outcomes
I think wave(s) ___ are most intense because ..."
(hint. Look at wavelength and amplitude)

8.

These graphs show the wavelength and amplitude of light coming from three lasers. Could any of these lasers be giving off a different type of light?
