Legend says that archimedes, in determining whether or not the king's crown was made of pure gold, measured its volume by the wa
ter displacement method. if the density of gold is 19.3 g/cm3, and the crown's mass is 600 g, what volume would be necessary to prove that it is pure gold?
Mass=volume x density if we have mass and density we can calculate volume using the formula: volume=mass/density volume of the displaced water = 600g/19.3g/cm3 volume = 31.09cm3
Answer: If the light ray hits the boundary at an angle which is not perpendicular to or parallel to the surface, then it will change direction and appear to `bend'
