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
Most musical sounds are composed of many frequencies. When playing a musical instrument or singing, the frequency of a sound wave affects the _____ of the sound. Measured in decibels, the _____ of a wave affects the _____ of a sound.
pitch, amplitude, loudness
loudness, speed, pitch
harmony, wavelength, loudness
loudness, harmony, pitch
What behavior of sound can cause the shattering of glass by the voice of a singer?
reflection
absorption
diffusion
resonance
Musical instruments are designed to produce a variety of sounds by changing the size of the parts on the instrument. A xylophone uses mallets that strike the bars to make sounds; whereas a Pan Flute uses forced air through columns to produce sound.
Select the area of each instrument that will produce the lowest pitch sound that the instruments are capable of making.
Put the musical instruments in the order they experience a change in resonance from highest frequency to lowest frequency.
1. Guitar
2. Cello
3. Violin

loosen the strings
remove the tightest string
increase the strings' tension
move the strings farther from the body of the guitar
Which of the following are NOT properties of light waves?
frequency
timbre
amplitude
wavelength
resonance
Identify the characteristics listed that describe a Sound Wave.
longitudinal wave
transfers energy from one point to another
the denser the medium, the faster the wave
transverse wave
travels through a vacuum
Identify the characteristics listed that describe a Light Wave.
longitudinal wave
transfers energy from one point to another

Electromagnetic energy travels in waves along a broad spectrum measured through the electromagnetic spectrum. This spectrum is used to describe the entire range of light that exists, including those the human eye cannot see.
What property of waves does the electromagnetic spectrum measure?
speed
amplitude
frequency
wavelength
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.
When sound waves move from a gas to a liquid, they _____.
When light waves move from a gas to a liquid, they _____.
speed up, slow down
slow down, speed up
speed up, stay the same
slow down, stay the same

1. Solids
2. Gases
3. Liquids
