Total Internal Reflection (TIR) + Apparent Depth Flashcards
1
Q

A
Total Internal Reflection
2
Q
critical angle formula
A
θ_c = sin^-1 (n_2/n_1)
3
Q
phenomenon when the observer perceives image within medium to be along refracted ray [a depth different from where it actually is]
A
apparent depth
4
Q
what is apparent depth denoted as
A
D_a
5
Q
what is real depth denoted as
A
D_r
6
Q
angular formula for n_water
A
n_water = sinθ_r/sinθ_i
7
Q
apparent depth formula for n_water
A
n_water = D_r/D_a
8
Q
formula for apparent depth via n_water
A
D_a = D_r/n_water
