Question

green light in the visible portion of the electromagnetic radiation sepectrum has a wave length around 550nm.Express this wavelength in meters using exponential notation

Answer 1

Answer:

$5.5 \times 10^{-7} \ m$

Explanation:

Given,

Wavelength = 550 nm

We know,

$1 nm = 10^{-9} \ m$

now,

$550\ nm = 550 \times 10^{-9}\ m$

                        = $5.5 \times 10^{-7} \ m$

Hence, the wavelength of light in meters is equal to $5.5 \times 10^{-7} \ m$
