# Apparent depth and the viewing angle [closed]

Does the viewing angle of a person observing a coin placed in a bucket of water affect the apparent depth in any way?

• This question appears to be off-topic because it is obvious. – Abhimanyu Pallavi Sudhir Feb 16 '14 at 15:17

• @Artemisia One thing you might want to try is drawing a very careful diagram showing light leaving an object under water at different angles. You'd need a protractor & such to get the angles just right. Trace back your rays and see if you're able to say either way. – BMS Feb 16 '14 at 15:32
• That helped provide the intuition to support the derivation given below :) Thank you – Artemisia Feb 16 '14 at 17:26

$$AD=\frac{RD}{n_{ab}}$$
Where $AD$ is apparent depth, $RD$ is real depth, and $n_{ab}$ is the refractive index of medium b (denser medium) w.r.t medium a (rarer medium).
