Answer:
The correct answer is B. You would not have to travel far to see another total eclipse .
Explanation:
it is said that the way to predict or know beforehand if there is a lunar or solar eclipse is just to know the what is called the saros which are periods of exactly 223 synodic months and the eclipses are repeated or occurred in the same location every 3 Saros cycles.
The answer is the third one down. New evidence may contradict the old evidence of a certain theory.
Answer:
option B
Explanation:
Given,
Refractive index of the glass, n₂ = 1.50
Refractive index of plastic, n₁ = 1.30
critical angle = ?
![\theta_{critical}=\sin^{-1} (\dfrac{n_1}{n_2})](https://tex.z-dn.net/?f=%5Ctheta_%7Bcritical%7D%3D%5Csin%5E%7B-1%7D%20%28%5Cdfrac%7Bn_1%7D%7Bn_2%7D%29)
n₁ is the refractive index of the rare medium
n₂ is the refractive index of the denser medium.
![\theta_{critical}=\sin^{-1} (\dfrac{1.30}{1.50})](https://tex.z-dn.net/?f=%5Ctheta_%7Bcritical%7D%3D%5Csin%5E%7B-1%7D%20%28%5Cdfrac%7B1.30%7D%7B1.50%7D%29)
![\theta_{critical}=\sin^{-1} (0.8667)](https://tex.z-dn.net/?f=%5Ctheta_%7Bcritical%7D%3D%5Csin%5E%7B-1%7D%20%280.8667%29)
![\theta_{critical}=60.1^\circ](https://tex.z-dn.net/?f=%5Ctheta_%7Bcritical%7D%3D60.1%5E%5Ccirc)
The correct answer is option B
