You have been studying heat energy transfer in science class. Your task today is to design a solar oven to make s'mores: graham crackers, marshmallows, and melted chocolate. When you have successfully completed your oven, you can eat the s'mores. Your group has constructed the solar oven you see here. How is the solar energy transferred into the oven and directed to the s'mores on the pan?
Solar energy is transferred via radiation.
Solar energy is transferred via convection.
Solar energy is transferred via conduction.
Solar energy is transferred via reflection.
Your solar oven was the most efficient of the designs in class and your s'mores were ready much faster than any other group's. What design features helped transfer heat energy efficiently and directly to the grahams and marshmallows?
The aluminum foil walls conducted heat energy toward the tin pan holding the s'mores. The tin pan radiated heat waves up towards the s'mores, causing them to absorb heat energy.
The aluminum foil walls reflected incoming solar energy to the pan and the s'mores. The tin pie pan heated up quickly because it is metal and conducted heat energy to the grahams.
The aluminum foil walls conducted heat energy toward the tin pan holding the s'mores. The tin pan, being metal and a good conductor, heated up quickly and melted the marshmallows.
The aluminum foil walls reflected incoming solar energy to the s'mores and the tin pie pan. The tin pie pan, because it is metal, quickly reflected the heat energy to the s'mores.
In which picture(s) will you find a state of matter that has particles who have more energy than liquid water?
B and C
A, B, and C
B, C, ad D
All of them
The speed of light was recorded as it passed through different media. The light passed through air, water, and glass. According to the graph, light waves travel
faster in glass than in water.
faster in air than in water.
faster in water than in air.
faster in glass than in air.
Which of the following diagrams represents the reflection of waves?
Media A, B, C, and D represent different mediums. The phenomenon in this diagram is BEST described as
diffraction
dispersion
reflection
refraction
Which statement best describes how sound transfers energy through different types of mediums?
Sound travels fast through solids because the particles are closer together.
Sound travels faster through space because there are no air particles to slow it down.
Sound travels the slowest through liquids because the particles are harder to move.
Sound travels at the same rate in any medium because the distance between the particles does not matter.
A student conducted an investigation to compare the quality of signal transmission of radio waves and microwaves through different materials. The student's data is shown in the table below. What can be concluded about the student's investigation?
The transmission quality of radio waves is unaffected by different materials and microwaves are not able to transmit through materials.
Radio waves and microwaves transmit well through air, plastic, and glass, but microwaves are more affected by the other materials.
Radio waves and microwaves transmit well through air, plastic, and glass, but transmission of both types of waves is reduced by wood, brick, and concrete.
Neither radio waves nor microwaves can effectively transmit through brick or concrete.
A student conducted an investigation into how different materials affect data signals transmitted by microwave, radio, and ultraviolet waves. Their experimental results are listed in the provided data table. What can be concluded about the student’s investigation? Select TWO correct answers.
The materials’ impact on data transmission varies depending on the type of wave.
The materials do not have an affect on the transmission of data by different types of waves.
The transmission of data signals by different types of waves is affected by the material it is moving through.
The properties of a material affects its ability to transmit data signals.
Wave properties are changed by the type of material it moves through.
A seismic wave from an earthquake traveling through Earth's mantle reaches the boundary between the mantle and the crust. The mantle and crust are different in many ways, including their density and composition. What happens as the seismic wave passes from the mantle to the crust?
The wave dissipates entirely when it reaches the boundary.
The seismic wave is completely reflected and does not pass into the crust.
The seismic wave continues traveling at the same speed, undisturbed by the transition.
The seismic wave changes direction and speed as it enters the crust.

A ship is mapping the structure of the ocean floor using sonar technology. Which statement describes the basic method used in this type of mapping?
A radio wave is sent from the ship and reflects off the ocean floor back to a receiver on the ship.
A sound wave is sent from the ship and reflects off the ocean floor back to a receiver on the ship.
A radio wave is sent by the ship and is absorbed by the ocean floor.
A sound wave is sent by the ship and is absorbed by the ocean floor.
Waves and Energy Review
A) The amplitude of a wave determines its speed.
B) The frequency of a wave is inversely proportional to its wavelength.
C) The energy of a wave is directly proportional to its frequency.
D) The speed of a wave is independent of the medium it travels through.
