Question

What is the frequency of a wave with a wavelength of 3.20 x 10^10 Hz

Answer 1

Answer:

3.20 x 10^10 = 32,000,000,000 = 1E-08

Step-by-step explanation:

f = C/λ

Where,

λ (Lambda) = Wavelength in meters

c = Speed of Light (299,792,458 m/s)

f = Frequency (MHz)

Answer 2

Answer:

Frequency, $f=9.37\times 10^{-3}\ Hz$

Step-by-step explanation:

Given that : The wavelength of the wave, $\lambda=3.2\times 10^{10}\ m$

To find : Frequency of a wave

Formula used : $f=\dfrac{c}{\lambda}$

Where c is the speed of light

We know that the relationship between the frequency, wavelength and the speed of light is given by :

$f=\dfrac{c}{\lambda}$

$f=\dfrac{3\times 10^8\ m/s}{3.2\times 10^{10}\ m}$

f = 0.009375 Hz

or

$f=9.37\times 10^{-3}\ Hz$

So, the frequency of a wave is $9.37\times 10^{-3}\ Hz$. Hence, this is the required solution.
