What is the frequency of a wave of intrared light which has a wavelength of 4.35 * 10 ^ - 5 meters?
weqwewe [10]

Answer

6.9 x 10¹²Hz

Explanation:

Given parameters:

Wavelength of the wave  = 4.35 x 10⁻⁵m

Unknown:

Frequency of the wave = ?

Solution:

The speed of a wave is related to the wavelength and frequency using the expression below;

          C  = Fλ

C is the speed of light = 3 x 10⁸m/s

F is the frequency

λ  is the wavelength

Insert the given parameters and solve;

      3 x 10⁸  = F x 4.35 x 10⁻⁵

         F  = \frac{3 x 10^{8} }{4.35 x 10^{-5} }   = 6.9 x 10¹²Hz
