Answer:
[tex]L=2.5*10^-^7m[/tex]
Explanation:
From the question we are told that
Frequency of light [tex]f= 600 THz[/tex]
Generally the equation for wave is mathematically given as
[tex]\lambda=\frac{c}{\gamma}[/tex]
Where
[tex]1THz=10^1^2[/tex]
[tex]\lambda=\frac{3*10^8}{600*10^1^2}[/tex]
[tex]\lambda=0.5*10^-^6m[/tex]
Generally the equation for a fundamental Frequency is mathematically given as
[tex]L=\frac{\lambda}{2}[/tex]
[tex]L=\frac{0.5*10^-^6}{2}[/tex]
Therefore the length of the smallest standing wave
[tex]L=2.5*10^-^7m[/tex]
