What determines if light will be reflected, refracted, or absorbed by an object?
How strong the light source is
What the object is made of
How big the object is
How smooth the object is
Energy waves bouncing off the surface of an object
Absorbed
Transmitted
Reflected
Transparent
How does light travel?
In circles
In waves
In zigzags
In curves
What object would best reflect a ray of light?
Mirror
Wood Table
Bottle of Water
Window
A form of energy that is part of the electromagnetic spectrum and exhibits wave-like behavior as it travels through space
Transmitted
Transparent
Reflected
Light
What does Transmitted mean?
Energy waves bouncing off the surface of an object
To soak up or take something in
When something is passed from one place to another
The ability for light to pass through so that objects behind can be seen distinctly
What happens when you place a container of water in the beam of a ray of light?
Light is mostly refracted.
Light mostly bounces off it.
Light is mostly absorbed.
Light is mostly reflected.
What is the best description of electromagnetic radiation?
Energy waves bouncing off the surface of an object
Energy that travels in the form of electromagnetic waves
A form of energy that is part of the electromagnetic spectrum and exhibits wave-like behavior as it travels through space
The ability for light to pass through so that objects behind can be seen distinctly
A student places a pencil in a glass of water and observes that the pencil appears to be broken. Which of these provides the best explanation for why the pencil appears broken?
The pencil absorbs all the lights rays that hit it.
The surface of the water reflects light rays.
Water reflects light rays away from the pencil.
Light rays are bent by the water in the glass.
The illustration shows the path of a laser leaving a laser pointer. At what point is the laser being absorbed?
A
B
C
D
The distance from Earth to the Moon can be accurately calculated by pointing high-powered lasers onto the Moon’s surface. The time it takes for the light to return is used to find the distance. To make this possible, astronauts on the Apollo 11 Moon mission had to place a device on the Moon that would –
store the laser light for future use.
bounce the laser light back to Earth.
allow the laser light to pass through.
change the frequency of the laser light.
Which of the following is the best example of an object absorbing light?
A black sweater in the sun.
A clean window in the sun.
A curved mirror in the sun.
A lnng shadow in the sun.
Solar panels generate electricity using photovoltaic cells that receive sunlight. To protect these cells from moisture while allowing sunlight to pass through, engineers must design a cover for the solar panel that is –
waterproof and transmits light
very flexible and reflects light
stronger than steel and bends light
cold to the touch and absorbs light
What is the difference between wavelength and frequency?
Wavelength measures distance between crests and frequency measures number of crests
Wavelength measures number of crests and frequency measures distance between crests
They are the same, there are no differences
Wavelength measures vertically while frequency measures horizontally
How is wavelength related to frequency?
They have NO relation
As the wavelength gets longer, the frequency gets higher
As the wavelength gets shorter, the frequency gets lower
As the wavelength gets shorter, the frequency gets higher
This lens will make the object appear squashed, but it will appear always right side up. The object is just smaller. (Side View Mirror of Vehicle)
Concave Mirrors
Convex Mirrors
Flat Mirrors
Wavy Mirrors
What occurs in order to allow us to see objects as different colors?
Light is absorbed by the object and goes into our eyes.
Light reflects into the object and off our eyes.
Light reflects off the object and into our eyes.
Light refracts off the object and into our eyes.
To soak up or take something in
