Higher Order Thinking Skills.
Light ray emerges from water into air. Draw a ray diagram indicating the change in its path in water.
उत्तर
When a ray of light travels from dense medium to rarer medium [from water medium to air medium], light ray moves away from the normal.
∴ Angle of incidence < Angle of refraction.
