Green light has a wavelength of 550nm. what is the frequency of a photon of green light?

- Frequency is .

Solution:- frequency and wavelength are inversely proportional to each other and the equation used is:

where, is frequency, c is speed of light and is the wavelength.

Speed of light is .

We need to convert the wavelength from nm to m.

( )

=

Now, let's plug in the values in the equation to calculate the frequency:

= or

since,

So, the frequency of the green light photon is .

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
