The picture shows two optical paths observed by Xiao Zhang and Xiao Li when they explore the refraction law of a light with tools such as optical discs. Xiao Zhang observes A.

(1) Comparing the observation results of the two men with the experimental conclusion, we can see that Xiao Zhang's observation results are correct, but the experimental conclusion is wrong. Because an experimental phenomenon is very accidental, it is too small to draw the conclusion that "in any case (when light refracts), the refraction angle is smaller than the incident angle". The occurrence of "the refraction angle is less than the incident angle" has specific conditions and is not simple. Therefore, when the light obliquely enters the water from the air, the refraction angle is not greater than the incident angle, but smaller than the incident angle. So Xiao Li has no clear concept about the angle of refraction.

(2) By further observing and comparing the two kinds of refraction in the figure, we can also find that when light obliquely enters water or other transparent media from the air, the refraction angle is smaller than the incident angle; Different media have different refractive power to light, and glass has stronger refractive power to light than water.

So the answer is: Xiao Zhang's observation is correct, but the experimental conclusion is wrong. According to an experimental phenomenon, it is impossible to draw the conclusion that "in any case (when light refracts), the refraction angle is smaller than the incident angle". The occurrence of "light refraction time" has specific conditions, not a simple "light refraction time". Xiao Li's observation and experimental conclusion are all wrong. The angle of refraction is the angle between the refracted light and the normal. Therefore, when the light obliquely enters the water from the air, the refraction angle is not greater than the incident angle, but smaller than the incident angle.
