What is the frequency of green light that has wavelength of 5.5x10⁷m?

5.5Hz

Explanation:

Given parameters:

Wavelength of green light  = 5.5 x 10⁷m

Unknown:

Frequency of the wave = ?

Solution;

Green light is a part of the electromagnetic spectrum. The speed of all these rays in free space is 3 x 10⁸m/s

So;

     V  = fλ

V is the speed

f is the frequency

λ is the wavelength;

 So;

         F =  

  Insert the parameters and solve;

       F =   = 5.5Hz

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
