Question

Does the apparent depth of a tank of water change if viewed obliquely? If so, does the apparent depth increase or decrease?

Short Note

Solution

Yes; Decrease

The apparent depth of a tank of water changes when viewed obliquely. This is because light bends on travelling from one medium to another. The apparent depth of the tank, when viewed obliquely, is less than the near-normal viewing.
