Rather than a normal bathtub which the water moves forwards, backwards, left and right, a whirlpool bathtub makes the water go clockwise/anti-clockwise to simulate a whirlpool effect.
When light travels from a less dense medium to a denser medium, it bends towards the normal. This is because light slows down in a denser medium, causing it to change direction. When light travels from a denser medium to a less dense medium, it bends away from the normal as it speeds up in the less dense medium.
Outdoor setting is louder.
The ray of light bends away from the normal when traveling from a less optically dense medium (medium A) to a more optically dense medium (medium B). Therefore, medium B is optically denser in this scenario.
No, a wave does not refract when it enters a medium along the normal line. Refraction occurs when a wave enters a new medium at an angle, causing it to change speed and change direction. If the wave enters the medium along the normal line, it will continue in the same direction with no refraction.

Solitaire is a style of setting for a ring: it provides one setting for a single gemstone. A 'normal diamond ring' can be any kind of diamond ring setting. A diamond is a diamond, regardless of its ring setting.
When light passes from one medium to another, it can be bent towards or away from the normal line (imaginary line perpendicular to the surface of the interface) depending on the relative optical densities of the two media. If the light is entering a denser medium, it will be bent towards the normal; if it is entering a less dense medium, it will be bent away from the normal.
