What characteristics should a medium in which we immerse an object and make it transparent (or invisible) to you? Explain and give at least one example.

Expert Solution

When the object is immersed in liquid or any other medium and we see that object is basically due to the concept of refraction and reflection of light. When the light rays fall on the object it gets either reflected of refracted which results in the visibility of the object. But if we take a madium with same refractive index as that of object then the light rays will not get reflected from the object and hence it will appear like only medium is present. Or we can say the object becomes invisible. For example when ice is immersed in the water with same impurities.i.e ice made from the same water and ice taken to be just after it is made. Then the light rays will pass straight through the ice appearing invisible.

Conclusion is that to make an object invisible the refractive index should be exactly same as that of medium.

If your doubt is cleared please give an upvote it means a lot. Its a humble request to you.

When a vertical beam of light passes through a transparent medium, the rate at which its intensity I decreases is proportional to I(t), where t represents the thickness of the medium (in feet). In clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity I0 of the incident beam. What is the intensity of the beam 13 feet below the surface? (Give your answer in terms of I0. Round any constants or coefficients to five...

“… the problem is which of two people should have an indivisible object, a “seller”(which originally has it) or a “buyer”. The efficient solution is that whoever values it more should have it, perhaps with some payment to the other.” (J. Farrell, Economics Perspectives, 1987, p. 120). Discuss all different types of auctions explaining which of these ensure that the principle in the above statement applies, why it leads to a Pareto efficient outcome and whether such a type of...
