प्रश्न
Draw a diagram showing the refraction of a light ray from water to glass. Label on it the incident ray, the angle of incidence (/), and the angle of refraction (r)

उत्तर
Water is rarer than glass.
Light travels from water to glass mean light travels from a rarer to a denser medium.
The incident ray is AO.
Angle of incidence is ∠i
Angle of refraction is ∠r
