Which drawing best shows how light travels from a car's headlights?
Two flashlights are turned on. The light rays they produce are shown in the diagram. These rays BEST illustrate that -
both rays are being reflected by the water.
both rays are being refracted by the water.
Ray1 is reflected and Ray 2 is refracted by the water
Ray 1 is refracted and Ray 2 is reflected by the water
A prism is used to—
block light rays
refract light rays
reflect an image
change heat into light
All of the following refract light EXCEPT -
Which of the following objects would BEST reflect light?
Waxed paper
Aluminum foil
Plastic wrap
Craft paper
What type of lens makes a good hand lens to magnify objects?
A shiny aluminum screen can be placed on the windshield of a parked car. This screen helps to keep the car cool because it—
reflects the sunlight
absorbs heat
causes evaporation
conducts electricity
The diagram shows a metal spoon in a glass of water. Which process causes the metal spoon to appear split or broken?
Absorption
Refraction
Transmission
Reflection
Which of the following best explains why it is harder to see your reflection in a rough surface than a smooth surface?
When light hits a rough surface, much of it is absorbed into the substance
When light hits a smooth surface, much of it is refracted so that it bends
When light hits a rough surface, much of it is reflected in many different directions
When light hits a smooth surface, the light is mostly converted to energy
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 scattered or curved
Sometimes it is possible to see light rays. An example is when sunlight is breaking through the clouds. Sunlight breaking through the clouds demonstrates how light rays travel in –
Straight lines
Curved rays
Zigzag rays
Circular waves
When light hits different types of objects, it acts differently depending on the object. Which object above best reflects light?
Sealable bag
Shower curtain
Aluminum foil
Drinking glass
Does water refract or reflect light?
refract
reflect
Refracts and reflects
Neither refracts nor reflects
Students were performing an investigation to compare and contrast the effects of reflection and refraction. What tools are most helpful to students when conducting this investigation?
Magnets, mirrors
Prisms, hand lenses
Hand lenses, cameras
Mirrors, prisms
Light travels into a camera lens to form a small, upside down image on the inside of the camera. Which of the following best describes why the lens flips and decreases the size of the image?
Light is refracted by the lens
Light is absorbed by the lens
Light is reflected by the lens
Light is transmitted by the lens
What happens when light strikes a dark, heavy object?
Light is refracted
The light moves quickly through the medium
Light energy is absorbed
Light does not strike dark objects
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
Reflection
Absorption
Refraction
Students performed an experiment testing refraction of objects in water. First, they recorded how objects looked in hot water. Then they used cold water to test if the appearance changed. What variable did students test in this experiment?
Temperature of water
The student who performed the experiment
Time of day the experiment was performed
The objects tested
Before beginning an experiment, students were instructed to gather the materials necessary to classify objects with the properties of reflection or refraction. What objects could be used as materials that reflect light?
Glass, water, and camera
Water, piece of wood, and clear plastic container
DVD, shiny pot, and mirror
Mirror, wood, water
After an experiment testing refraction of light in water, a student made the following conclusion:
Objects look broken when they are in water so light is reflected in water.
Was the student’s conclusion accurate?
Yes, because when objects appear broken in water, they are reflected
Yes, because all objects can reflect light
No, because objects submerged in water do not appear broken
No, because objects appear broken in water due to refraction of light
While investigating whether objects reflect or refract light, a student asked when would be an appropriate time to make a conclusion. What is a good response to this question?
After performing experiments one time, a reliable conclusion can be made
No matter how many times an experiment is tested, you should never make a conclusion
Test the experiment several times to ensure your conclusion is accurate
No, because objects appear broken in water due to refraction of light
While investigating whether objects reflect or refract light, a student asked when would be an appropriate time to make a conclusion. What is a good response to this question?
After performing experiments one time, a reliable conclusion can be made
No matter how many times an experiment is tested, you should never make a conclusion
Test the experiment several times to ensure your conclusion is accurate
All responses are correct
Bifocals were invented in 1784 by a famous scientist named Benjamin Franklin. He invented bifocals to make it easier to see both up close and far away. Bifocals are a type of glasses which 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 refract light
The bifocal lenses reflect light
The bifocal lenses make light less visible
The bifocal lenses absorb light
When exploring light in an outdoor investigation, which safety rule should be followed?
Never look directly at the Sun
Wear a lab coat or apron
Wear sandals or open-toed shoes
When waiting for directions, play with your friends
