When light crosses the boundary between layers with different densities, the light is refracted. (A).
Answer:
Please show the warning's
Explanation:
v
Convert the given temperatures from celsius to kelvin since we are dealing with gas.
To convert to kelvin, add 273.15 to the temperature in celsius.
T1 = 22 + 273.15 = 295.15 k
T2 = 4 + 273.15 = 277.15 k
V1 = 0.5 L
Let's find the final volume (V2).
To solve for V2 apply Charles Law formula below:
That n2 = 2*n1. That is, the index of refraction is twice as big in medium 2 since v=c/n
Basically it is the difference in velocity divided by the time it takes to make that change.
