Refractive Index of Air with Respect to Water
The refractive index of a medium with respect to another medium is the ratio of the speed of light in the first medium to the speed of light in the second medium. Given that the refractive index of water with respect to air is 1.33, we need to find the refractive index of air with respect to water.

Formula
The formula to find the refractive index of a medium with respect to another medium is:
\[ \text{Refractive Index} = \frac{\text{Speed of Light in 1st Medium}}{\text{Speed of Light in 2nd Medium}} \]

Calculation
Given that the refractive index of water with respect to air is 1.33, we have:
\[ \text{Refractive Index of Water with Respect to Air} = \frac{\text{Speed of Light in Water}}{\text{Speed of Light in Air}} = 1.33 \]
Therefore, the speed of light in water is 1.33 times the speed of light in air.
To find the refractive index of air with respect to water, we can rearrange the formula as:
\[ \text{Refractive Index of Air with Respect to Water} = \frac{\text{Speed of Light in Air}}{\text{Speed of Light in Water}} = \frac{1}{1.33} = 0.7518 \]
Therefore, the refractive index of air with respect to water is 0.7518, which corresponds to option B.
