Light waves travel in which type of lines
Straight
A living organism that gives off light is called
Bioluminous
This type of object blocks all light
Provide an example
Opaque
Your head
What is reflection?
Light bouncing off an object
What are 2 examples of refraction
Light shining through a prism.
Viewing an item through different types of matter.
ie. water and air
Draw a compression wave on the board and label the amplitude, trough, crest, medium, wavelength
We will inspect your wavelength!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
What creates white light.
Use an "R" word
All colors of the visible spectrum being refracted
This type of object lets all light through
Give an example
Transparent
Clear glass
What tool uses the law of reflection to allow someone under water to see above water.
Periscope
Solid, gas, liquid
Tell how the speed of light is impacted by going through the above.
Light goes through________________ fastest,
_____________2nd fastest, ___________slowest
gas, liquid , solid
The high point of a wave is called the
Crest
What percent of the electromagnetic spectrum does the visible light spectrum occupy?
75 percent
3 percent
25 percent
This type of object allows some light through and blocks other light
Provide an example
Translucent
Wax paper
Light shade
What is the Law of Reflection
Angle of reflection equals angle of incidence
When light is refracted, does in still travel in transverse waves?
Yes indeedeee
The longer the wavelength the _____________ the frequency
Lower , less, etc....
Using the visible light spectrum, including indigo, which color represents the median in the spectrum?
ROYGBIV
G would be the middle color and would represent the median of the spectrum; therefore Green.
When light shines on a opaque object it can cause a ________________ on the other side of the object
Shadow
Light reflects best off objects that are.......
Flat, smooth and shiny
The lower the frequency of a light wave the _____________ powerful the wave.
Less
Light travels at what speed
a. 200 km/sec and reaches earth in 10.2 seconds
b. 500 km/sec and reaches earth in 6 seconds
c. 300 km/sec and reaches earth in 8.3 seconds
How is a rainbow created during a storm?
The white light refracts through rain droplets and splits the white light into the colors of the VLS.
As light travels and reaches a new material, the light can be either_______________,_____________or_________
absorbed, transmitted or reflected
The angle in which light bounces off an object is called? A.
The angle in which a light hits an object is called? B.
A. Angle of reflection
B. Angle of incidence
What changes in light as it goes through different mediums
The speed of the light
