Green light in the visible portion of the electromagnetic radiation spectrum has wavelengths around 550 nm.Express this wavelength in meters using exponential notation.

Question

Quizplus · Accepted Answer

The wavelength of green light in meters can be found by dividing 550 nm by the conversion factor of 10^9 nm/m. This gives:
550 nm ÷ 10^9 nm/m = 5.5 x 10^-7 m
Expressing this in exponential notation, we get:
5.5 x 10^-7 m = 5.5 x 10^-1 x 10^-6 m = 5.5 x 10^-7 m
Therefore, the best choice is B, which expresses the wavelength as 5.5 x 10^-7 m.
