Question

Part A Check all that apply.
The two materials have matching indexes ofrefraction. The second material through which lightpropagates has a lower index of refraction. The second material through which lightpropagates has a higher index of refraction. The two materials are identical.

Part B The same monochromatic light passes throughthe interface between two other unknown materials. This time thetransmitted wave is observed to be farther from the normal to theinterface than the incident wave. What can be said about these twomaterials and the light traveling through them? Check all that apply.
Refracted Waves in Unknown Materials Part A When monochromatic light passes through theinterface between two unknown materials at an angle where , nochanges in the direction of propagation of light are observed. Whatcan be said about the two materials? Check all that apply.

The second material through which the lightpropagates has a higher index of refraction. The second material through which the lightpropagates has a lower index of refraction. As the light passes into the second material,its speed increases. As the light passes into the second material,its speed decreases.

Explanation / Answer

A) The two materials have matching index of refraction. Two materials can be different but have the same index ofrefraction (for example. Ethanol and Acetone have the same index ofrefraction.) B) The second material through which the light propagates hasa lower index of refraction.        As the light passes into thesecond material, its speed increases. Cannot read your fifth possibility on B ifthere is one!
