Welcome to the forum. Please note that you should post your attempt or state your difficulty in order that we can guide you to solve the problem. As you are a new comer, I will help you this time.

For the light ray to diverge, one thing you should consider is the thickness of lens is thinner at the centre when compared to the edges.
