oh boi icse students have that in class 10th half yearly. Its damn easy
Hi
Ray optics is a fairly easy chapter, even with respect to class 12th Physics. But, some important topics include refraction, reflection and the natural phenomena. What I would suggest you to do is, look at past year KVPY questions from the chapter, and analyse for yourself. Because all the topics are related, you might have to go through everything once.
