Refractive Index Experiment Quiz

What is the purpose of tracing the edge of the semicircular block on paper?

• To create a permanent mark
• To visualize the path of light
• To measure the diameter
• To find the center of the block

When light passes through the semicircular block, what happens to the angle of incidence at the normal?

• It increases
• It decreases
• It remains the same
• It becomes zero

What is the relationship between the angle of incidence and the angle of refraction in this experiment?

• They are equal
• They are complementary
• They follow Snell's Law
• They are unrelated

Why does the emerging ray pass to air without refraction?

• It is at a critical angle
• It strikes the surface normally
• It is absorbed by the medium
• It reflects back into the block

What does the equation sin(i) = n * sin(r) represent in this context?

• The speed of light in air
• The refractive index of the medium
• The angle of incidence
• The angle of refraction
