Light Waves 1
The higher the _______________ the brighter the light.
Amplitude
Frequency decides what in a light wave?
Color
Give an example of light waves being transmitted
Possible Example: Light is going to go through clear glass
Can be transmitted, reflected, absorbed
Both
In what wave property does refraction relate to? Wavelength, amplitude, or frequency?
Frequency
Light is a form of....
energy
Amplitude decides what in a light wave?
Brightness of the color
Is there any material that transmits 100% of a light?
No
Is it light, sound, or both?
Type of wave that can be seen
Light
Why are there different shaped lenses? What can they do to images?
the different shapes cause light to refract in different ways, either magnify or demagnify an image.
The shortest wavelength in visible light is what color?
Purple
Give an example of a light wave being reflected
Answers will vary. Possible example: shining a light on aluminum foil, the brightness of the light is reflected back to your eyes
Does a little bit of light reflect off ALL objects? Yes or no, why?
Yes. If it didn't, we wouldn't be able to see the object.
Is it light, sound, or both?
Type of wave that can be heard
Sound
How is a concave lens shaped?
Thin at the center, thicker on the edges
The highest wavelength in visible light is what color?
Red
Give an example of a light wave being absorbed
Answers will vary. Possible example: black shirt will absorb the sun rays and turn it into heat.
Explain what is happening to light waves if you look at a red apple. Use the words reflect and absorb in your explanation.
All of the other colors of visible light are being absorbed into the apple. Red light is being reflected off the apple into our eyes.
Is it light, sound, or both?
Can transfer energy from one place to another
Both
How is a convex lens shaped?
Bulge out in the middle
Light waves travel fastest through what?
Air
Give an example of a light wave being refracted
Answers will vary. Possible example: putting a pencil in a cup of water, pencil looks like it's bending
What are all the colors of visible light?
*Bonus 100 points if you name them IN ORDER from least amount of frequency to highest amount of frequency*
Red, orange, yellow, green, blue, indigo, violet/purple
Is it light, sound, or both?
Can travel without a medium
Light
Are light waves going to be refracted more in air, water, or glass? Why?
Glass. Glass is more dense than water or air.
