The wavelength of a light wave as it passes through a material is 423.34 nm with a speed of 201,611,579.2 m/s. What is the frequency of this wave?

Respuesta :

Given:

• Wavelength = 42334 nm

,

• Speed of wave, v = 201,611,579.2 m/s

Let's find the frequency of the wave

To find the frequency of the wave, apply the formula:

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

Where:

f is the frequency in Hz.

v is the speed in m/s.

λ is the wavelength in meters.

Thus, we have:

[tex]\begin{gathered} f=\frac{201611579.2}{423.34\times10^{-9}} \\ \\ f=476240.325 \\ \\ f=4.76\times10^{14}\text{ Hz.} \end{gathered}[/tex]

Therefore, the frequency of the wave is 4.76 x 10¹⁴ Hz.

• ANSWER:

4.76 x 10¹⁴ Hz.
