Step 1: Define the portion of the electromagnetic (EM) spectrum perceivable by humans, referred to as the visible spectrum. This range of light wavelengths corresponds to the colors of the rainbow.
Step 2: Specify the wavelength range of the visible spectrum. It typically spans from approximately 400 nanometers (nm) for violet light to about 700 nanometers (nm) for red light.
Step 3: Convert this range into meters.
Given that 1 nm = 10\(^{-9}\) m.
- 400 nm = 400 \(\times\) 10\(^{-9}\) m = 0.4 \(\times\) 10\(^{-6}\) m
- 700 nm = 700 \(\times\) 10\(^{-9}\) m = 0.7 \(\times\) 10\(^{-6}\) m
Therefore, the range is from 0.4 \(\times\) 10\(^{-6}\) m to 0.7 \(\times\) 10\(^{-6}\) m. This is also commonly expressed as 0.4 to 0.7 micrometers (\(\mu\)m).
