T/F The more light reaches your eyes, the brighter an object will appear to you.
True
False
The slower the particles in a substance move,
the colder it is & less energy they have.
the colder it is & the more energy they have.
the warmer it is & the more energy they have.
the warmer it is & the less energy they have.
Experiments are often repeated many times. What is the most important reason why someone should conduct an investigation using the same methods?
Different scientists might perform the experiment differently
More than one scientist is interested in the problem.
The competition makes the scientists work more carefully.
If the results are the same, replication of the investigation helps to confirm the results.
What occurs inside a raindrop to make a rainbow?
The light enters one side raindrop & leaves the other side
The light circles inside the raindrop before leaving the same way
The light enters the raindrop & then reflects out light on same side
None of these
White light enters a prism & leaves as____________.
Black light
The colors of the rainbow (ROYGBIV)
Red light
None of these
What has to happen for a liquid to become a gas?
The temperature decreases causing the liquid to become a gas
The temperature remains the same & the liquid becomes a gas
The temperature increases causing the liquid to become a gas
All of these
T/F When a scented candle is warmed the ability to smell it from greater distances is reduced because of an increase in energy.
True
False
The blue light is shining on the green grass in the blue field. Explain how light moves to your eyes.
The blue light is transmitted to the green grass & blue field. At which point, the color of blue is reflected & blue is seen in the eye
The blue light is transmitted to the green grass & blue field. At which point, the colors are reflected & cyan is seen in the eye
The blue light is transmitted to the green grass & blue field. At which point, the color of the field is reflected & seen in the eye as blue; however when the blue light strikes the green grass, the color of blue light is absorbed & the green appear black
None of these
T/F White light has to leave a raindrop or prism in order for the components of a rainbow to be visible by the eye.
True
False
You see black when__________
There is no light present
Your retina are overloaded with light
The optical nerve increases in size
All of these
T/F The warmer gas particles get the faster they move & further they spread out in an area.
True
False
Explain how light interacts with a prism.
Light reflects off the prism & then separates white light individually
Light circles around the prism separating white light individually
Light is absorbed causing all the colors of white light to be seen
Light is bent slightly in the prism & then it exists separating all of the colors of white light
The sun is transmitting white light to the red flower in the green field. Explain the movement of light to your eyes.
The white light (ROYBGIV) is transmitted to the red flower & green field. The color red from the flower is reflected to the eye but the color green from the field is absorbed & appears black in your eye.
The white light (ROYGBIV) is transmitted to the red flower & green field. The color red from the flower & green from the field mix together in your eye & you see both as yellow in your eye.
The white light (ROYGBIV) is transmitted to the red flower & green field. The color red from the flower & color green from the field are reflected to your eye allowing your to see both colors.
None of these
Which type of glass would you use to maximize the temperature inside a greenhouse in cold weather?
Opaque allowing little or no light to enter the greenhouse
Transparent allowing most of the light to enter the greenhouse
Translucent allowing some of the light to enter the greenhouse
None of these
The process of light being bent slightly is called____________.
Scattering
Absorption
Refraction
Transmission
What happens when a green film is placed over a flashlight?
The flashlight with the green film absorbs all white light & everything is seen as black in your eyes
The flashlight with the green film mixes with the white light & everything is seen as neon yellow in your eyes.
The flashlight with the green film absorbs all the white light & only the color green is visible in your eyes.
None of these

You see white
You see black
You see orange
You see yellow
