To solve this problem it is necessary to apply an energy balance equation in each of the states to assess what their respective relationship is.
By definition the energy balance is simply given by the change between the two states:
Our states are given by
In this way the energy balance for the states would be given by,
Therefore the states of energy would be
Lowest : 0.9eV
Middle :7.5eV
Highest: 8.4eV
Answer:t=0.1205
Explanation:
Given
Refractive index of oil
Wavelength of red light =675 mm
Condition for constructive interference is
For m= 1 i.e. for minimum thickness
Answer:
4.416 W/m²
Explanation:
Malus' law is given mathematically as
I = I₀ cos² θ
For the first polarizer, θ = 60°
I₁ = I₀ cos² 60°
I₁ = I₀ (0.5)² = 0.25I₀
For the second polarizer, θ = 20°
I₂ = I₁ cos² 20°
I₂ = I₁ (0.9397)² = 0.883 I₁
I₂ = 0.883 × 0.25I₀ = 0.2208 I₀
Note that
I₀ = 20 W/m²
I₂ = 0.2208 × 20 = 4.416 W/m²
Hope this Helps!!!
Given:
Speed = 3.5 m/s
Distance = 20 m
To find:
Time taken
Solution:
Speed = Distance/Time
so
Time = Distance/Speed
Substituting given values, we get
Time = 20/3.5
<em>Time = 5.714 seconds</em>
