1. Four students attempt to label a wave diagram. Based on the responses from each student, who correctly labeled the wave?
Mary says:
A=Amplitude
B=Crest
C=Trough
D=Equilibrium
E=Wavelength
Jo says:
A=Wavelength
B=Trough
C=Equilibrium
D=Amplitude
E=Crest
Beth says:
A=Wavelength
B=Crest
C=Equilibrium
D=Amplitude
E=Trough
Amy says:
A=Wavelength
B=Crest
C=Amplitude
D=Equilibrium
E=Trough

Amy correctly labeled the wave
The whistle produces a soundwave that is high in pitch and low in loudness. Belle the dog, with her sensitive hearing, was able to detect the high-frequency whistle sound that was beyond the range of human hearing.
Based on the responses, Beth correctly labeled the wave.
Four students made claims as to the relationship between wavelength and frequency. Which student(s) have made a correct statement? At least one student is correct but there might be more than one.

Without the specific claims made by each student, it is not possible to determine which student(s) have made a correct statement about the relationship between wavelength and frequency. If you provide the claims made by each student, I can help identify the correct statement(s).
Which of the following surfaces is LEAST likely to produce an echo?
*
1 point
Styrofoam
Wood
Glass
Stone
Styrofoam is the least likely surface to produce an echo because it is highly absorbent and not reflective, which reduces the likelihood of sound waves reflecting off the surface and creating an echo.
Below is a picture of some water waves approaching an island. Pay close attention to where the waves are coming from. As the waves come in contact with the island, they begin to bend around the shore of island. This results in the waves spreading out around the island to encircle the beach behind the island. This is an example of which wave process?

Refraction
Diffraction
Transmission
Diffusion
This is an example of the wave process known as Diffraction.
Robin and Maxine were both playing in the snow with Maxine's dog Belle. Suddenly, Belle started running toward the house after Maxine's mom blew a dog whistle. The girls, were initially confused, as they did not hear any sound. Which answer BEST explains why Belle the dog could hear the whistle but the girls could not?
