As a race car drives away from an observer, the observer notes that the sound from the car gets quieter and the pitch lowers. Which statement BEST describes how the sound wave changes as the race car drives away?
The frequency increases and the amplitude increases.
. The frequency increases and the amplitude decreases.
The frequency decreases and the amplitude increases.
The frequency decreases and the amplitude decreases.
An advertisement claims that a new type of cotton cloth looks red because of the way the cloth is woven and not because of the dye used on the cloth. Which statement BEST explains why the chemical dye is responsible for the red appearance of the cloth?
The chemical absorbs the light from the visible spectrum except for red that is reflected to the eye.
The chemical absorbs all the red light from the visible spectrum that is reflected to the eye.
The light is refracted and the longest wavelength shows through the one that is red.
The chemical reaction produces a red light that is emitted, so the cloth looks red.
Which of these will remain unchanged when a sound wave travels from the air to water?
amplitude
frequency
speed
wavelength
A lab group designs an experiment to test which of four identical bottles will produce the sound with the highest pitch when air is blown across the opening at the top. Their initial hypothesis is that the highest pitches are produced when equal amounts of water and air are in the bottle. When blowing air across the tops of the bottles, Bottle 4 produces the sound with the highest pitch.
Which would be the BEST hypothesis based on their results?
The pitch of the sound produced when air is blown across a bottle does not depend on the contents of the bottle, but only on the size of the bottle.
The highest pitches are produced when the total mass of air in the bottle is greater than the total mass of the water in the bottle.
Sounds with the highest pitch are produced when all air is removed from the bottle.
The pitch of the sound increases as the amount of air in the bottle decreases.
A machine converts sound into a transverse wave as shown.
If the sound becomes louder, what would the new sound wave look like?
Student 1 claims that energy can only be transferred by particles inside a medium. Student 2 does not agree with Student 1.
Which statement should Student 2 use as evidence that Student 1 is INCORRECT?
Light energy can travel without a medium.
Sound energy can travel without a medium.
All types of energy can travel without a medium.
Mechanical energy can travel without a medium.

In order for a fish to see a bug just above the surface of the water, light travels from the insect through the air and crosses into the water until it reaches the fishes' eye.
Which statement is true regarding the light wave as it travels?
It will bend as it hits the water because it slows down.
It will bend as it hits the water because the water particles move slower than air.
It will travel straight from the bug to the fishes' eye because that is the most direct path.
It will travel straight from the bug to the fishes' eye because it will continue to travel at the speed of light.
