Question 939978
The frequency of a photon of light is related to its wavelength by the following formula:

{{{c = (Wavelength)(Frequency)}}} 

{{{wavelength=lambda}}}

{{{frequency=c/lambda}}}

where {{{c=3*10^8( m/s) }}} is the speed of light.
What is the frequency of a photon with a wavelength of {{{lambda=5*10^(-9 )m}}}

{{{frequency=3*10^8(m/s)/(5*10^(-9 )m)}}}


{{{frequency=(3*10^8(cross(m)1/s))/(5(1/10^9 )cross(m))}}}


{{{frequency=((3*10^8)/s)/(5/10^9 )}}}


{{{frequency=(3*10^8*10^9 )/5s}}}


{{{frequency=(3*10^17 )/5s}}}

{{{frequency=(3*cross(10)2*10^16 )/cross(5)s}}}


{{{frequency=3*2*10^16(1/s)}}}


{{{frequency=6*10^16(1/s)}}}


answer is: {{{(6*10^16)/s}}}
