Wavelength = Speed/Frequency

Speed = speed of light = 3*10^8 m/s
Frequency = 8.9*10^9 Hz

Wavelength = (3*10^8)/(8.9*10^9) = 0.0337 m

Answer:

0.034m

Explanation:

The wavelength is the distance between two consecutive ridges or valleys

And it is defined by the following equation:

[tex]\lambda=\frac{V}{f}\\ V=speed\\f=frequency[/tex]

Data

[tex]V= 3.00.10^8 m/s\\f= 8.90.10^9 hz[/tex]

Now we substitute in the equation

[tex]\lambda=\frac{V}{f}\\\lambda=\frac{3.00.10^8m/s}{8.90.10^9hz} \\\lambda= 0.034m[/tex]

the wavelength is 0.034m
