We can solve this problem by using the distance formula. The distance formula is:
We can now put in values and solve.

Every 60 seconds in Africa a minute passes together we can stop this
The value of the 7 are
one of them is one hundred thousand
the other one is one hundred
We have been that frequency (y) varies inversely with wavelength (x).
We know that two inversely proportional quantities are in form
, where a is inversely proportional to b and k is constant of variation.
Our required equation would be
.
To find frequency of blue light, we will substitute
and
in our equation as:


Therefore, the frequency of blue light is 764.
