What is this image an example of?
transmission
What is this image an example of?
refraction
Which material will absorb more light? Why?
Asphalt, it is darker than concrete so it will absorb more light
What is different about these two waves?
top - longer wavelength and low frequency, bottom - shorter wavelength, high frequency
What part of a wave is the orange box?
crest
What part of a wave is the red box?
wavelength
Which wave will have a higher pitch?
bottom wave
Draw a picture on you desk of how a normal lens transmits light
It should transmit through the lens in a straight line
What part of a wave is the green box?
trough
What is this image an example of?
absorption
Draw a picture on your desk of how a concave lens refracts light
It should refract at the thicker part of the lens
What part of a wave is the blue box?
amplitude
What is similar about these two waves?
similar amplitudes
Draw a picture on your desk of how a convex lens refracts light
It should refract at the thicker part of the lens
What is this image an example of?
reflection
