is the two human body have different refractive index
Several examples: density, color, refractive index, crystalline structure, melting point.

This is because it belongs to the cubic group of minerals where the refractive index of light is common in all orientation. The velocity of light is the same in all directions.
opaque
Not exactly. A solid can be transparent and translucent also. What opaque means is no quanta can pass through it. So yes.
Physical properties of benzoic acid:-density: 1,2659 g/cm3-melting point: 122,41 oC-boiling point: 249,2 oC-refractive index: 1,5397
most solid materials are opaque because they are dense. things like liquids and gases are more spread out, that is why they aren't opaque.
sulfur power is opaque yellow coloured solid
The object must be opaque, solid or liquid.
There are many objects that no light can pass through, although of course, it depends on what type of light you're talking about. The name of the type of object that visible light cannot pass through is called opaque.
The speed of light through a solid will depend on its refractive index. Water ice has a refractive index (RI) of 1.31 and so light will travel at a speed of 228,850,000 metres per second. Germanium has a RI approx 4 and so the speed of light is 74,950,000 metres per second. Then there are opaque solids and the speed of light through these is 0.
