## Homework Statement

Find the length of the smallest standing wave that can be formed with light having a frequency of 600THZ.

## Homework Equations

[tex]f = 600*10^{12}Hz[/tex]

[tex]c = 2.998x10^{8}\frac{m}{s}[/tex]

[tex]\lambda f=c[/tex]

## The Attempt at a Solution

[tex]\lambda f=c[/tex]

[tex]\lambda (600*10^{12}Hz)=(2.998x10^{8}\frac{m}{s}[/tex]

[tex]\lambda = \frac{2.998x10^{8}\frac{m}{s}}{600*10^{12}Hz}[/tex]

[tex]\lambda = 4.997x10^{-7}m[/tex]

I think something is wrong because it is asking me to find a the "smallest" indicating that the wave can multiple values.
