The wavelength of a light wave as it passes through a material is 657.61 nm with a speed of 232,536,355.7 m/s. What is the frequency of this wave?

Sagot :

Given:

The wavelength of light is

[tex]\begin{gathered} \lambda\text{ = 657.61 nm} \\ =657.61\times10^{-9}\text{ m} \end{gathered}[/tex]

The speed is v = 232536355.7 m/s

Required: The frequency of the wave.

Explanation:

The frequency can be calculated by the formula

[tex]f=\frac{v}{\lambda}[/tex]

On substituting the values, the frequency will be

[tex]\begin{gathered} f=\text{ }\frac{232536355.7}{657.61\times10^{-9}} \\ =3.536\times10^{14}\text{ s} \end{gathered}[/tex]

Final Answer: The frequency of the wave is 3.536e14 s
