The wavelength of blue light is typically in the range of about 450 to 495 nanometers (nm). To express this in the same form as your provided value, we can convert nanometers to meters.
1 nanometer = \(1 \times 10^{-9}\) meters.
So, for blue light:
- 450 nm = \(450 \times 10^{-9}\) m = \(0.000000450\) m
- 495 nm = \(495 \times 10^{-9}\) m = \(0.000000495\) m
Your value of \(0.000000492\) m (or 492 nm) falls within the reasonable range for the wavelength of blue light. Therefore, it can be considered a reasonable estimate for the wavelength of the color blue.
