High Energy = ______ Frequency
High Frequency
100
Define REFLECTION?
Wave strikes an object or surface and bounces off
100
Define REFRACTION
The bending of a wave as it moves from one medium into another
100
Diffraction
100
True or False
High Energy =Low Amplitude
False
High energy = High Amplitude
200
What feature best distinguishes one form of electromagnetic energy from?
Wavelength, Energy Amount, Frequency
200
What do all electromagnetic waves travel in and what is true about how all electromagnetic waves travel ?
They all travel at the same speed in a vacuum.

Grayson places a bar of Ivory soap on a plate in the microwave. He knows that the bar of soap contains a lot of air and that microwaves increase the movement of molecules. He heats the soap on high for one minute and notices that it increases in size. Why did this happen to the bar of soap?
The air in the soap expanded.
The air in the soap moved faster.
200
Which color has the HIGHEST amount of energy on Visible Light Spectrum
Which color has the LOWEST amount of energy
Violet (highest)
Red (lowest)

Anna throws a rubber ball at a wall, and it bounces back to her.
This situation best describes what? (Hint think of reflection refraction diffraction)
Echo
300
Using the Electromagnetic spectrum which wave has the highest amount of energy?
Gamma
300
Why does sound travel quickly in a solid but slower in gas. (Hint work smarter not harder)
solids have particles that have very little distance between them
solids allow sound waves to move a greater distance in less time
300
Describe the difference between a Electromagnetic wave that is also transverse and a Mechanical wave that is transverse
Electromagnetic (Transverse)waves DO NOT require a medium for energy to travel while Mechanical (Transverse) waves do.
300
Which substance is the densest for sound waves to travel?
Copper, Water, Air
Copper

Dillon wraps his remote with aluminum foil to see if he can block the radio waves released by the remote control used to operate his radio-controlled car. Did the remote control work once covered with foil, EXPLAIN why if yes. EXPLAIN why if no AND which wave it blocked.
No, because the aluminum foil blocks the radio waves
400
How does increasing the amount of energy in a wave affect its characteristics? Describe 3
The wave's amplitude and frequency increases, while the wavelength becomes shorter.
400
What does the time line suggest about scientific knowledge throughout the years?
It suggests that scientific knowledge changes over time, as shown by the new discoveries made about lenses leading to changes in their uses.
400
What is the difference between a reflected and a diffracted sound wave?
A reflected sound wave bounces back to the place of origin. A diffracted sound wave changes direction as it passes through an opening.
400
Describe what happens when a sound wave refracts
The wave changes the direction when passing from one medium to another
It changes its speed and wavelength from one medium to another
400
Sort the following according to how fast sound will travel through the medium: liquid, solid, gas. Give examples of each type of medium
Solid (fastest) such as metal or glass, Liquid such as water, gas (slowest) such as air

Camden constructs a model of a double convex lens using two clear plastic circles that are round on one side and flat on the other. He attaches the circles at the edges. How does his model look?
It is thicker in the middle and thinner at the edges.
500
Aila draws a model of a double convex lens. She draws horizontal lines to show light rays traveling toward the lens. What happens to the light rays after they move through the lens?
They refract and converge to a point
500
A student creates a model of a lens. The diagram shows her model
Convex
500
What type of lens is this?
Concave

Radar allows pilots to see through clouds, rain, darkness, and fog. It can detect objects so a pilot can avoid hitting them. Radar is also used by the police to detect the speeds of cars on the highway. Radar uses radio waves. Explain why gamma rays are not used for radar instead of radio waves.
Gamma rays are not used because they are harmful to human beings due to their high energy content.
