Answer:
Δy= 5,075 10⁻⁶ m
Explanation:
The expression that describes the interference phenomenon is
d sin θ = (m + ½) λ
As the observation is on a distant screen
tan θ = y / x
tan θ= sin θ/cos θ
As in ethanes I will experience the separation of the vines is small and the distance to the big screen
tan θ = sin θ
Let's replace
d y / x = (m + ½) λ
The width of a bright stripe at the difference in distance
y₁ = (m + ½) λ x / d
m = 1
y₁ = 3/2 λ x / d
Let's use m = 1, we look for the following interference,
m = 2
y₂ = (2+ ½) λ x / d
The distance to the screen is constant x₁ = x₂ = x₀
The width of the bright stripe is
Δy = λ x / d (5/2 -3/2)
Δy = 630 10⁻⁹ 2.90 /0.360 10⁻³ (1)
Δy= 5,075 10⁻⁶ m
Answer:
correct is the A
Explanation:
The light is a wave that has travels from two different places, each side of the circular obstacle, so an interference process must be given, which is described by the expression
a sin θ = m λ
Where a is the size of the slit, λ the wavelength and m an integer that indicates the order of diffraction.
In the case of the central point, the difference in the optical path of each ray stop is zero, which implies that in some it is also zero, so the waves are in phase for this point and a bright spot must be seen in the center.
When reviewing the answer the correct one is the A
Atomic number, atomic mass
The third one is your answer
