Reflection is a change of the angle of light without a change of medium. Refraction is a change of the angle of light with a change of medium.
Optical dense refers to the index of refraction. If one medium is optically denser than another, then its index of refraction is larger, meaning the speed of light in the optically denser medium is smaller.

Buoyant - is something that 'floats' on the surface of whatever medium it is resting on. For example a boat on water is buoyant.
actually light is nothing but combination of so many Waves. so we can say that light and waves are not different things that means if a light can move through a medium we an say that the waves an also move through that so medium refers the same meaning both in terms of light and waves

A 9K race is 5.59 miles.
It is: -4(9k-6) = -36k+24
it is identical to the original rbk 9k hoackey stick but miniature
A 9k run is nine kilometers or 5.6 (5.59234) miles.
Better to lose a 9k gold ring than a 18k one ! 18k is purer gold than 9k.
The implied coefficient in front of ' K ' = 1 so, 1K + 9K = 10K ----------
Greatest common factor of 18k and 3375k is 9K.
In United States Of Amirica Don't has value 9k of alloys soft gold !
no such thing
Need to know the prefix letter or number and letter before the 9k number.
9k is different from 18k or 24k because 24k is pure gold and 18k and 9k have more metals in them so that helps the become more endurable. but if you want pure metal get 24k
