$400 Question from C4
Compare infrared light and ultraviolet light.
This light has the longer wavelength and
this is the reason why.
$400 Answer from C4
Infrared light has a longer wavelength.
The two have the same speed, so the one
with the lower frequency has a longer
wavelength.

$500 Question from C4
Radiation from a distant star is very strong at
a star. However, it is very faint by the time
it reaches Earth. What do you think happens
to the radiation as it moves through space
that might explain this?
$500 Answer from C4
The radiation is very strong at the object, but it is
very faint when it reaches Earth because the
radiation spreads out as it travels. Therefore,
only a small part of the radiation from distant
objects reaches Earth.

Final Jeopardy
1. What happens when you mix all three
primary colors of light in equal amounts?
What happens when you mix all three
primary pigments in equal amounts?
What explains the difference? Think
about how each group combines to make
other colors. Does mixing add or
subtract wavelengths?
Final Jeopardy Answer
1. Mixing primary colors of light adds
wavelengths together. When you mix all
the wavelengths of light, you get white light,
so when you combine the primary colors,
you get white. The primary pigments each
absorb all but one color, so as you mix them,
they absorb more wavelengths. This means
that you are subtracting wavelengths.
When you subtract all the wavelengths,
you get black.
