Question

Olivia is intersted in art and science and remembers that each color has a diffrent wavelength.Oliva science teacher says that yellow has a wavelength of around 5.8 X 10 negative 9 exponet, green has a wavelength of around 5.5 X 10 negative 9 exponet, blue has a wavelength of around 4.9 X 10 negative 9, and violet has a wavelength of around 4.1 X 10 negative 9, Which color has the greatest wavelength?

Answer 1

yellow

Answer 2

how?

Answer 3

Because all of them are to the negative ninth power, you just look at which one is the largest decimal.

Answer 4

really?

Answer 5

1 X 10 negative 9 exponent {METERS}
\[=1 \times 10^{-9} meters = nano meter \]
ie yellow is 5.8 nanometers , 5.8nm
...
blue is 4.2nm

all datum is wavelength given in the same units
find the largest ; it is yellow
