A certain electromagnetic radiation has a wavelength of 5.4x10-7m. What is the frequency of this electromagnetic radiation?
O 1.8 x 10-65-1
O 5.6 x 1014 5-1
O 1.6 x 1011 51
O 1.8 x 10-155-1
O 5.6 x 10551

5.6 x 10¹⁴m

Explanation:

Given parameters:

Wavelength  = 5.4 x 10⁻⁷m

Unknown:

Frequency of the electromagnetic radiation = ?

Solution:

The speed of all electromagnetic radiation is given as 3.0 x 10⁸m/s

  So;

         Speed = frequency x wavelength

  Wavelength =

 Insert the parameters and solve;

   Wavelength =  

  Wavelength  =  x 10⁸⁻⁽⁻⁷⁾

  Wavelength  = 5.6 x 10⁻¹ x 10¹⁵

   Wavelength  = 5.6 x 10¹⁴m

i'm wiling to try and you : )
