Answer:
0.26086 Hz
Explanation:
solution:
The relative speed of the wave is:
v = 4.9+1.1 = 6 m/s
the frequency is:
f = v/λ
= 6/23
= 0.26086 Hz
Try liters if you haven’t done it yet. I’m so sorry if i’m incorrect.
Answer:
θ = 41.8º
Explanation:
This is an internal total reflection exercise, the equation that describes this process is
sin θ = n₂ / n₁
where n₂ is the index of the incident medium and n₁ the other medium must be met n₁> n₂
θ = sin⁻¹ n₂ / n₁
let's calculate
θ = sin⁻¹ (1.00 / 1.50)
θ = 41.8º
