# Graph of the Frequency(Wavelength) Relationship

#### tenbee

1. Homework Statement

A practice problem showed the relationship between frequency and wavelength to be inversely exponential. I don't understand why is the graphical relationship is not [instead] inversely linear. What concept am I missing? (No calculus please... I'd be clueless ).

2. Homework Equations

v = ƒ$\lambda$

3. The Attempt at a Solution

Reading my text book to no avail.

What do you mean by inversely linear? If you express frequency in terms of wavelength, for example, you get an inverse exponential function (i.e. variable is in the denominator).

$f=\frac{v}{\lambda}$

how is it exponential function then?

OP is right.
it is inversely proportional function (or inversely linear)

Exponential functions could also be referring to functions of the from

$y=\large\frac{1}{x^{n}}$
