The speed of light in four different materials is shown below: material speed of light in thousand miles per second a 140 b 78 c 186 d 124 which material is the least dense? material a material b material c material d

It is C I just did the test for segment two at flvs and I got it right + think of it like this the denser the less water (or in this case light) can get through because it is pact really close together while if it isn't really dense you can get more water (or in this case light) through hope this helps

So more dense less through so more dense would be B and less dense would be C because more gets through

something that more overed sayed the samie is how they were govered they were govered by lords which is now called dictator ship

the answer is c.
