Question

What is In Case Apparent Shift of an Object due to Refraction?

Answer

In Case Apparent Shift of an Object due to Refraction - Case I : If μ₂ > μ₁, i.e. observer is in denser medium. Then, shift becomes negative, image distance > object distance, i.e. image is further from the refracting surface, Case II : If μ₂ < μ₁, i.e. observer is in rarer medium. Then, shift becomes positive, image distance < object distance, i.e. image is closer to the refracting surface, Case III : If μ₂ = 1 and μ₁ = μ [Apparent shift = Real depth (1 - 1/μ)]
