Answer
Given,
refractive index of film, n = 1.6
refractive index of air, n' = 1
angle of incidence, i = 35°
angle of refraction, r = ?
Using Snell's law
n' sin i = n sin r
1 x sin 35° = 1.6 x sin r
r = 21°
Angle of refraction is equal to 21°.
Now,
distance at which refractive angle comes out
d = 2.5 mm
α be the angle with horizontal surface and incident ray.
α = 90°-21° = 69°
t be the thickness of the film.
So,
t = 2.26 mm
Hence, the thickness of the film is equal to 2.26 mm.
1 mole of plutonium = 244 gm
3.6 kg of plutonium = 3.6 × 1000 = 3600 gm
Number of moles = 3600 ÷ 244 = 14.754 moles
One moles of plutonium contains protons =
Total number of protons in 14.754 moles =
Total number of protons in 14.754 moles =
