An empty spherical flask of diameter 100 cm is placed in water. A parallel beam of light strikes the flask. Where will it appear to come from to an observer within the flask
Answers
Answer:
Explanation:
=> Here, An empty spherical flask of diameter 100 cm is placed in water.
Thus, diameter, d = 100 cm
radius, r = 100/2 = 50 cm
Refractive index of air, μ₁ = 1
Refractive index of water, μ₂ = 4/3
Image distance, u = ∞
Object distance, v = ?
=> μ₂/-u + μ₁/v = μ₁-μ₂/R
0 + 1/v = 1 -4/3 /50
1 / v = -1 / 150
v = -150 cm
It will appear to come from to an observer within the flask from distance of 150 cm.
