12. Rainbows are visible because
a)
White light is reflected off of raindrops
b)
the visible light spectrum has seven colors
c)
white light is refracted by the raindrops
d)
the amplitude of each color varies
13.
13. Which statement is most correct?
a)
When white light enters a water droplet, the light bends at different rates. Red bends the most and violet bends the least
b)
each color in the spectrum refract at a different angle. Violet refracts the most and red refracts the least.
