If the speed of light in vacuum is $3 imes 10^8$ m/s and its frequency is $6 imes 10^{14}$ Hz, what is its wavelength?

Question

If the speed of light in vacuum is $3 	imes 10^8$ m/s and its frequency is $6 	imes 10^{14}$ Hz, what is its wavelength?

Accepted Answer

0.5 μm. Using $\lambda = \frac{c}{f}$, we get $\lambda = \frac{3 	imes 10^8}{6 	imes 10^{14}} = 0.5 	imes 10^{-6}$ m. This equals $0.5$ μm.

If the speed of light in vacuum is $3 \times 10^8$ m/s and its frequency is $6 \times 10^{14}$ Hz, what is its wavelength?
