Radio, Micro, Infrared, Visible, Ultraviolet, X, or Gamma Rays.
100
How are mechanical sound waves caused?
Energy causes particles in a medium to vibrate
100
Name one surface that refracts light.
Water, Jell-O, Prism
100
What is it called when a light beam bounces off a surface?
Reflection
100
Which color of light has the longest wavelength and the lowest energy?
Red
200
What electromagnetic energy has the shortest wavelength and the highest energy?
Gamma Rays
200
What do mechanical waves need to travel?
A medium
200
What happens to a beam of light when it is refracted?
The light is bent.
200
What happens to a beam of light when it strikes a mirror?
It is reflected.
200
Which color of light has the shortest wavelength and the highest energy?
Violet
300
What is the main characteristic that distinguishes one form of electromagnetic energy from another?
Wavelength
300
Can sound waves travel through outer space? Why or why not.
No, space is a vacuum therefore there would be no medium from the waves to travel through.
300
Why does a pencil look bent in water. Be more specific than water refracts light.
The light is bent and travels slower in the water and the reflection of the light off the object makes it appear to be in a different place than it really is.
300
What happens to a beam of light when it passes through a glass window?
It is transmitted.
300
What is the difference between chemical and kinetic energy?
Chemical energy is generated by a chemical change. Kinetic energy is generated by movement.
400
Explain how wavelength is different from amplitude.
Wavelength is the horizontal distance from crest to crest. Amplitude is the vertical distance from the rest position to the crest or trough.
400
What type of medium does sound travel fastest through?
Solid
400
Name a substance from Tuesday's lab that refracted the light. Explain your reasoning.
Water, Hair gel
400
Does a campfire reflect, transmit, or emit light?
Emit.
400
Name the colors of visible light in order from longest to shortest wavelength.
Red, Orange, Yellow, Green, Blue, Indigo, Violet
500
Name one dangerous aspect of a gamma ray.
Kills cells (used to kill cancer cells), radiation such as nuclear explosions
500
What do sound waves transmit from the speaker to your ear when a radio is playing music?
Energy
500
How does a prism affect a beam of light?
Separates out the different wavelengths of visible light.
500
Why do skiers wear sunglasses or goggles?
The snow reflects light.
500
Name a type of electromagnetic energy that has a shorter wavelength than visible light.
