We are given the data for the angle of incidence and angle of refraction.
The first part of the problem is to plot the deviation and the angle of incidence. The minimum deviation is 37 with 65 degrees as the corresponding angle of incidence. The maximum deviation is 69 with a corresponding angle of incidence of 30 degrees. It is not advisable to use small values for the angle of incidence since it would result to a higher deviation from Snell's Law.
To solve this problem it is necessary to apply the concepts related to Wavelength depending on the frequency and speed of light.
The equation that meets these parameters is given by
Where,
c = Speed of light
f = Frequency
Our values are given as
velocity of light in free space
f = 2Hz
Replacing we have that
Therefore the correct answer is B.
C
The atomic mass is the sum of the number of neutrons and protons.
No, because the word might offend that person.
Total time elapsed is =8.2y
The starting event is the astronaut leaving Earth. The finishing event is the astronaut arriving at the star system. The time between these events on Earth is:
Δt=3.9ly/0.9c
Δt=4.3y
For the astronaut, two events occur at the same position and can be measured with just one clock. Hence,
Δτ
Δτ
Δτ=1.8ly
The total elapsed time is:
T elapsed=Δt+3.9
T elapsed=4.3+3.9
T elapsed=8.2y
