(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

show that minimum thickness of quarter wave plate is d=[itex]\lambda[/itex]_{0}/4(n_{1}-n_{2}

2. Relevant equations

[itex]\lambda[/itex]_{1}=[itex]\lambda[/itex]_{0}/n_{1}

[itex]\lambda[/itex]_{2}=[itex]\lambda[/itex]_{0}/n_{2}

3. The attempt at a solution

for quater wave plates wavelengths must differ by 1/4

i can see its simple but i just cant see what i do
