suppose we have a medium in which light travels faster than in air. If a swimming pool is filled with this medium what will be the Apparent depth in relation to the real depth of the pool? why?

because in water the light travellers very slow and in oil it can not go very fastly and in air or vacuum it travellez very speed

so what?
it was denser medium so light will flow slow

Refractive index of that medium will be less than 1. So the usual apparent depth/real depth formula will be effectively like the reciprocal of its usual formula.
It is like you are inside water, you are looking at an object outside in air. So the light rays will be going away from the normal to the surface of that medium on refraction.
The apparent depth will be more than the real depth, as the refractive index of that medium is less than 1. The formula that is applicable for this situation is as follows:
Real depth / Apparent depth = μ
