Answer:

200 nm

Explanation:

We need a constructive interference to see the bright reflection

we know that $2t=m\lambda$ where m=1 and $\lambda$ is the wavelength of the gasoline

so $\lambda =\frac{560}{1.4}=400nm$

putting the value of m and $\lambda$ in thickness equation

$t=\frac{1\times 400}{2}=200nm$

so the thickness of the film will be 200 nm
