Mr. Lyall, the band director at Plano High School noticed one of his trumpet players had a change in pitch during a football game. After the game, Mr. Lyall asked the student to play for him and realized the pitch was still not quite right. The student then explained he had borrowed the trumpet from a neighbor because his was being repaired. Trumpet A, the student’s trumpet is the correct pitch for the sound Mr. Lyall expected to hear. However, Trumpet B is what was being played from the neighbor’s trumpet.
Choose a word for each blank to complete the sentence below.
Mr. Lyall was expecting to hear a ______ with a lower amplitude sound and instead, the student was playing a ______ and a higher amplitude.
higher frequency, lower frequency
higher frequency, higher pitch
lower frequency, higher frequency
lower frequency, lower pitch
Mrs. Brandon's class was experimenting with different forms of waves. She had one student go outside of her classroom, shine a light on the wooden classroom door, and then scream towards the door.
What behavior of waves is Mrs. Brandon trying to explain?
Lightwaves can be seen through mediums.
Mediums cause waves to behave differently.
Sound waves cannot be heard through a medium.
Mediums have no effect on waves. Each wave behaves independently of the medium.
Which color waves have the lowest frequency?
red
yellow
green
violet

In the illustration, the light ray striking the object is-
If the angle of incidence in the diagram is 50 degrees, which statement is true?
The angle of reflection is 40 degrees because is is measured from the normal line, which is 90 degrees
The angle of reflection is 50 degrees because it is equal to the angle of incidence.
The angle of reflection is 60 degrees, because it is greater than the angle of incidence.
The angle of refraction is 50 degrees, because it is equal to the angle of incidence.
