That links provided below are great resources. If you want to practice the questions for refraction of light. the first link shows you multiple choice questions which are related to the refraction of life for the JEE main entrance exam which generally focus on the snells law ray diagrams or specifically the critical angle question there are some question Also which involve questions on applications of refraction like lenses prisms and other optical instruments. the second link includes questions specific to the behaviour of life through the glass slab which focus on the deviation of light shifting of image and application in medical instruments. You can check out both the link. for the questions
