For the total internal reflection of a substance, we can express the relationship between the critical angle,
, and the indices of refraction as
(1) <span>
</span>
where
and
are the indices of refraction. And under polarization, we can express Snell's Law as
Rearranging this we have
(2)Substituting equations (1) into (2), we have
Substituting the value of the critical angle, we have
Answer: 33.79°
This occurs when the internal energy of the solid increases, typically by the application of heat or pressure, which increases the substance's temperature to the melting point. At the melting point, the ordering of ions or molecules in the solid breaks down to a less ordered state, and the solid melts to become a liquid.
Answer:
Which has more inertia - a car with a mass of 900kg or a car with a mass of 1500kg - explain. The bigger the mass - the larger the inertia but you need to exert more force to start the movement.
Explanation:
Answer: electromagnetic radiation
Explanation: range of wavelengths is called visible light or simply light. A typical human eye will respond to wavelengths.
