When waves traveling in the same medium meet, a new

Physics

hammer [34]3 years ago
8 0

Answer:

if there is any phase between the waves this value is less

if the sine function is ±, the amplitude of the total wave is

               A_total = A₁ + A₂ + A₃+ A₄ +A₅

Explanation:

When several waves travel in the same direction, the process of adding them can take place.

               y_total = ∑ y_{i}

     where

         y_{i} = A_{i} sin (k x - w t + Ф)

with fi the phase of each wave

       To produce the largest possible result, all waves must come with the same phase

                y_total = (A₁ + A₂ + A₃ + A₄ + A₅) sin (k x - wt)

if there is any phase between the waves this value is less

if the sine function is ±, the amplitude of the total wave is

               A_total = A₁ + A₂ + A₃+ A₄ +A₅

An electron (restricted to one dimension) is trapped between two rigid walls 1.40 nm apart. The electron's energy is approximate
Bumek [7]

Answer:

a)    n = 9.9       b)      E₁₀ = 19.25 eV

Explanation:

Solving the Scrodinger equation for the electronegative box we get

         Eₙ = (h² / 8m L²2) n²

where l is the distance L = 1.40 nm = 1.40 10⁻⁹ m and n the quantum number

 In this case En = 19 eV let us reduce to the SI system

          En = 19 eV (1.6 10⁻¹⁹ J / 1 eV) = 30.4 10⁻¹⁹ J

          n = √ (In 8 m L² / h²)

let's calculate

          n = √ (8  9.1 10⁻³¹ (1.4 10⁻⁹)²  30.4 10⁻¹⁹ / (6.63 10⁻³⁴)²

          n = √ (98)            n = 9.9

since n must be an integer, we approximate them to 10

b) We substitute for the calculation of energy

        In = (h² / 8mL2² n²

        In = (6.63 10⁻³⁴) 2 / (8 9.1 10⁻³¹  (1.4 10⁻⁹)² 10²

        E₁₀ = 3.08 10⁻¹⁸ J

we reduce eV

      E₁₀ = 3.08 10⁻¹⁸ j (1ev / 1.6 10⁻¹⁹J)

      E₁₀ = 1.925 101 eV

      E₁₀ = 19.25 eV

the result with significant figures is

        E₁₀ = 19.25 eV
