Does water refract or reflect light?
Only refracts light
Only reflects light
Refracts and reflects light
Not here
What happens when light hits an object that it cannot pass through?
The light is refracted or absorbed
The light is reflected or absorbed
The light is reflected or refracted
The light is refracted or curved
A man floating in a boat on a lake sees an image of an airplane in the water. At the same time he hears a plane and turns to see the source of the sound in the sky.
Which property of light best explains why an image of the plane appears in the water?
Conduction
Absorption
Refraction
Reflection
In an activity, a man stood in water.
Why does the bottom half of the man appear to be larger than the top half?
Reflection
Absorption
Conduction
Refraction
Students classify objects by the properties of reflection and refraction. Which is a list of object that best reflect light?
Prism, water, camera
Water, cardboard, clear container
Foil, shiny pan, mirror
Mirror, wood, water
What is shown in the image below?
The force needed to push a swing
The path light takes when it is refracted
The flow of electrical current
The path light takes when it is reflected
Which science tool could be used to refract light?
Mirror
Foil
Telescope
Fiberoptic wire
What is the difference between reflection and refraction?
Light bends when it is reflected and bounces off when it is refracted.
Light bounces off when it is reflected and bends when it is refracted.
Light travels in curved lines when it is reflected and straight lines when it is refracted.
When light is refracted, it no longer travels.
Bifocals were invented in 1784 by Benjamin Franklin. He invented bifocals to make it easier to see both up close and far away. Bifocal eyeglasses have two different lenses. One lens helps people to see at a distance, and the other is for seeing up close. Why can people who are both nearsighted and farsighted see better through bifocals?
The bifocal lenses reflect light.
The bifocal lenses refract light.
The bifocal lenses make light less visible.
The bifocal lenses absorb light.
When designing an experimental investigation, why is it important to test only one variable?
Testing one variable explains what caused the change, once data has been gathered.
Testing one variable collects inaccurate data and repeats the investigation more than necessary.
Testing one variable decreases the reliability of the investigation.
It is not necessary to test only one variable.
What force is being tested when an object is forced downward toward the center of Earth?
Gravity
Air pressure
Magnetism
Friction
Rubbing two sticks together to make a fire is an example of -
gravitational force
frictional force
pulling force
magnetic force
Which of the following is an example of magnetic force?
A ball rolls off a table and moves towards the floor.
An iron nail moves towards an object located 10 cm away.
A liquid is poured into a glass and settles to the bottom.
An acorn detaches from a tree and falls to the ground.
Which action would result in an object moving to the left?
A push from the left of an object.
A pull from the right of an object.
A push from the right of an object.
All of these.
