Answer:
the firtz agrees with the expression for the shape of the curve of diracion of a slit
Explanation:
The diffraction phenomenon is described by the expression
a sin θ = m λ
where a is the width of the slit, t is the angle from the center of the slit, l is the wavelength and m is an integer that corresponds to the maximum diffraction.
the previous equation qualitatively describes the curve of the diffraction phenomenon the equation takes the form
I = I₀ [(sin ππ a y / R λ) / π a y / Rλ]²
I = I₀ ’[sin π a y /Rλ]²
I₀ ’= I₀ / (π a y /Rλ)²
By reviewing the two expressions given
equation 1
w sin θ = m λ
where w =a w is the slit width
we see that the firtz agrees with the expression for the shape of the curve of diracion of a slit

Answer:
y = 2.74 m
Explanation:
The linear thermal expansion processes are described by the expression
ΔL = α L ΔT
Where α the thermal dilation constant for concrete is 12 10⁻⁶ºC⁻¹, ΔL is the length variation and ΔT the temperature variation in this case 20ªc
If the bridge is 250 m long and is covered by two sections each of them must be L = 125 m, let's calculate the variation in length
ΔL = 12 10⁻⁶ 125 20
ΔL = 3.0 10⁻² m
Let's use trigonometry to find the height
The hypotenuse Lf = 125 + 0.03 = 125.03 m
Adjacent leg L₀ = 125 m
cos θ = L₀ / Lf
θ = cos⁻¹ (L₀ / Lf)
θ = cos⁻¹ (125 / 125.03)
θ = 1,255º
We calculate the height
tan 1,255 = y / x
y = x tan 1,255
y = 125 tan 1,255
y = 2.74 m
Answer:
Δθ = 0.3 °
Explanation:
For this exercise we will use the law of refraction
n₁ sin θ₁ = n₂ sin θ₂
Where n₁ and n₂ are the refractive indices and θ are the incident and refracted angles
We apply this equation for each wavelength
Red λ = 600
The refractive index of air n₁ = 1
Let's calculate the angle of refraction (θ₂)
sin θ₂ = n₁ / n₂ sin θ₁
sin θ₂ = 1 / 1,455 sin 49.7
sin θ₂ = 0.52417
θ₂ = sin⁻¹ (0.52417)
θ₂ = 31.6 °
Violet λ = 410 nm
Sin θ₃ = 1 / 1,468 sin 49.7
θ₃ = sin⁻¹ (0.5195)
θ₃ = 31.3 °
The angle of dispersion is
Δθ = θ₃ - θ₂
Δθ = 31.6 - 31.3
Δθ = 0.3 °
