Chapter 12.2, Problem 14R

To determine

To Convert:The given units into meters.

Answer to Problem 14R

The required wavelength in meters is $0.00000069\text{m}$ .

Explanation of Solution

Given:

Wavelength of light is $69\text{0}\text{nm}$ .

Formula:

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

  $\text{1nm}=0.000000001\text{m}$

Calculation:

  $\begin{array}{c}690\text{nm}\text{=}\text{690×1}\text{nm}\\ \text{=}\text{690}{\text{×1×10}}^{\text{-9}}\text{nm}\\ \text{=}\text{690×0}\text{.000000001}\text{m}\\ \text{=}\text{0}\text{.00000069}\text{m}\end{array}$

Conclusion:

Hence, the required wavelength in meters is $0.00000069\text{m}$ .
