ANSWER

Yes frequency depends upon wavelength.

In case of periodic waves, frequency is inversely proportional to the wavelength.

1.) f = v/w [Here f= frequency; v= phase velocity & w= wavelength]

In the special case of electromagnetic waves moving through a vaccum, then v = c , where c is the speed of light in vaccum, as a result of which the expression further becomes :-

2.) f = c/w

[NOTE :- When waves from a monocrom source travel from one medium to another, their frequency remains exactly the same - only their wavelength & speed changes.]
