$75 It gets louder. Scores

Describe the double slit experiment. What did it prove? $100 Describe the double slit experiment. What did it prove?

$100 The double slit experiment showed that light acts both as a wave and a particle. In the experiment light was shot through 2 slits, one photon at a time. The pattern formed was an interference pattern that only occurs when waves interact. Scores

What is black light really? $25 What is black light really?

$25 The absence of color Scores

$50 Why does light bend around a corner?

$50 Light bends around a corner because it acts like a particle and a wave at the same time. Scores

What are the colors used to print a full color picture in a book? $200 What are the colors used to print a full color picture in a book?

Cyan, yellow, magenta and black $200 Cyan, yellow, magenta and black Scores

$50 Why is the sky blue?

$50 Because the molecules in the upper atmosphere scatter short frequency waves more often than long frequency waves resulting in a blue color. Scores

Daily Double

Why are the oceans blue/green? $100 Why are the oceans blue/green?

$100 Because water absorbs red frequencies of light, reflecting green and blue. Scores

$150 Why are the sunsets red?

$150 Sunsets are red because the light goes through more atmosphere, resulting in more time for the colors to refract, leaving only the red and oranges. Scores

What color are the daytime skies on the moon? Why? $200 What color are the daytime skies on the moon? Why?

$200 Black, because there is no atmosphere to refract the light, leaving it black. Scores

What is the source of electromagnetic waves? $50 What is the source of electromagnetic waves?

$50 Vibrating objects Scores

What is the Doppler effect? $100 What is the Doppler effect?

$100 The Doppler effect occurs when waves are push closer together as a result of an object moving towards you, or pulled apart as the object moves away from you. Scores

Describe the Doppler effect in respect to the red shift, blue shift. $150 Describe the Doppler effect in respect to the red shift, blue shift.

$150 As a star moves towards the Earth, the light waves are pushed closer so the color is bluish. If a star is moving away from the Earth, the waves are farther apart so they appear more reddish. Scores

$200 Describe what happened to the Tacoma Narrow bridge and why it happened.

$200 The Tacoma Narrows Bridge collapsed because the wind speed matched the natural frequency of the bridge, setting up a standing wave that cause the failure of the bridge. Scores

$50 What are beats and how can you calculate the frequency of a second tuning fork if the first has a frequency of 512 Hz and you hear 4 beats?

$50 Beats are produced when two sound frequencies occur that are very close in range. If one tuning fork has a frequency of 512 Hz and you hear 4 beats/second, the second tuning fork is either 508 or 516 Hz. Scores
