The results showed that the greater the length of the index finger relative to the ring finger, the better the ... more testosterone there is floating around, the longer the index finger, and the team also think that testosterone could ...
Could someone be so short sighted they can see at night?
... The reason the cornea can focus is because the refractive index of air and water are different. But as soon as you put your head under water, the refractive index of the water and the liquid within the eye are the same ... I believe that this is because water has a different index of refraction in air, where our eyes have been designed ...
Down to Earth: optical measurement technique
... it shifts is determined by the material’s refractive index. Water has a higher refractive index than air, which is why things look distorted when you look through a glass of it. However, the refractive index can change with the density of fluid too. Schlieren ...
What causes a mirage in the road?
... the lens is made of a glass which has different refractive index from the air around it. Air also has its own refractive index which depends on the temperature of the air. So, if you have hot air, it has different refractive index to if you have cold air. On a hot day, the sun will ...
