Light
What colors are contained within white light?
All of them
Would something with a large amplitude sound soft or loud?
Loud
If something has a low measurement of kinetic energy, would it feel hot or cold?
Cold
What do we call the range of colors that the typical human eye is able to see?
Visible Spectrum of Color
What two types of circuits did we learn about?
True or False:
Light waves have similar properties to sound waves. (amplitude, wavelength, frequency)
True
Define sound
What is kinetic energy?
The energy of motion
What color is the longest wavelength that the human eye can see?
From which end of a battery do electrons flow out of it?
Negative
What color absorbs the most light?
Black
What is the range of hertz than can be heard by the human ear?
20 Hz - 20,000 Hz
As water heats up, what happens to the particles within the liquid?
They heat up, speed up, and begin to spread out.
What color is the shortest wavelength that the human eye can see?
Violet
What is the purpose of a switch within a circuit?
The switch either connects or disrupts the flow of electrons/power.
What happens when white light waves travel through a prism?
Because the colors within white light all have a different wavelength, they are bent at different speeds, and the colors spread out.
What happens to a sound as its wavelength decreases?
The frequency increases, and it has a higher pitch
Provide an example of radiation heat transfer.
Holding your hand over a flame
Feeling the warmth of the sun
Name both ends of the spectrum that the human eye cannot see.
Ultraviolet and Infrared
Describe the difference between a series circuit and a parallel circuit.
A series circuit has all resistors on one connection, sharing the same current. The resistors in a parallel circuit each have their own path, and can pull their own current.
Explain refraction
A light's rays are deflected from a straight path as it passes from one medium (air) to another (water).
Explain the doppler effect.
As the distance changes between the source and its observer, the frequency of the sound waves increases or decreases.
What is the difference between convection and conduction?
Convection is heat transfer through a liquid, and conduction is heat transfer through a solid.
If you look at a red apple under a blue light, what color will the apple appear?
Black (it absorbs all of the blue light; there is no red light for the apple to reflect back to our eye)
If two bulbs are connected in a series circuit, why will they appear dimmer?
The same amount of current is being shared between the two bulbs, lower the current that each is receiving.
