Possible Example: Light is going to go through clear glass
Can be transmitted, reflected, absorbed
Both
Someone in your group do 10 pushups to get 200 points
WOO
Light is a form of....
energy
Amplitude decides what in a light wave?
Brightness of the color
Draw a wave and label all of the following parts: wavelength, amplitude, crest, trough
Is it light, sound, or both?
Travels fastest through solid objects
Sound
A wave with a large wavelength will have a ______ frequency and _____ energy
Low
Low
The shortest wavelength in visible light is what color?
Purple/Violet
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
What are the highest energy waves of the electromagnetic spectrum called?
Gamma Rays
Is it light, sound, or both?
Type of wave that can be heard
Sound
If light hits a material and a change occurs, this means the light is ____________.
Absorbed
The longest 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 each visible wave 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
Explain why my brake lights appear red when illuminated. Use the words transmit and absorb to explain your answer.
The brake lights are red because it only allows red light to transmit through the filter. The other colors of visible light are absorbed.
True or False Light waves can travel in space because they do not need a medium to travel through.
True
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.
