Answer:
The color blue emerges at 19.16° and the color red emerges at 19.32°.
Explanation:
The angle at which the two colors emerge can be calculated using the Snell's Law:
![n_{1}sin(\theta_{1}) = n_{2}sin(\theta_{2})](https://tex.z-dn.net/?f=n_%7B1%7Dsin%28%5Ctheta_%7B1%7D%29%20%3D%20n_%7B2%7Dsin%28%5Ctheta_%7B2%7D%29)
Where:
n₁ is the refractive index of the incident medium (air) = 1.0003
n₂ is the refractive index of the refractive medium:
blue light in crown glass = 1.524
red light in crown glass = 1.512
θ₁ is the angle of the incident light = 30°
θ₂ is the angle of the refracted light
<u>For the red wavelengths we have:</u>
![\theta_{2} = arcsin(\frac{n_{1}sin(\theta_{1})}{n_{2}}) = arcsin(\frac{1.0003*sin(30)}{1.512}) = 19.32 ^{\circ}](https://tex.z-dn.net/?f=%20%5Ctheta_%7B2%7D%20%3D%20arcsin%28%5Cfrac%7Bn_%7B1%7Dsin%28%5Ctheta_%7B1%7D%29%7D%7Bn_%7B2%7D%7D%29%20%3D%20arcsin%28%5Cfrac%7B1.0003%2Asin%2830%29%7D%7B1.512%7D%29%20%3D%2019.32%20%5E%7B%5Ccirc%7D%20)
<u>For the blue wavelengths we have</u>:
Therefore, the color blue emerges at 19.16° and the color red emerges at 19.32°.

Answer:
No, he won't be drowned.
Explanation:
We have given,
The height of the student = 5 feet,
Depth of the pool( in feet ) = x ( say ) < 5 feet,
Since, the depth of the pool < height of the student,
Thus, if the student went for swimming in a pool, however he does not know swimming, he will not be drowned until he is suffering from an injury or external force.
Answer:
the one in which the fluid has the lowest density
Explanation:
The figure that accompanies the question shows the wavelenghts of the photons emitted according to Balmer series transition , from energy levels (n) 3, 4, 5, and 6 to the energy level (n) 2, in hydrogen atoms.
These are the values shown in the figure
Transition wavelength of the photon emitted
nm
from n = 3 to n = 2 656 <------------- this is the value requested
from n = 4 to n = 2 486
from n = 5 to n= 2 434
from n = 6 to n = 2 410
The wavelength of a photon emitted from the n = 3 shell in hydrogen is the first data of the table, i.e 656 nm.
Using the conversion factor from nm to m that result is:
656 nm * 1 m / (10^9 nm) = 656 * 10 ^ - 9 m.
