Longitud wave something like that.
Answer:
Explanation:
a ) The angle between the polarization axis of two adjecent sheet
= 90 / 3 = 30 degree.
The formula for intensity of polarised light from unpolarised light ( first transmission
I₁ = I₀ /2
I₀ is intensity of unpolarised light and I₁ is intensity of light after first time polarization .
The relation of I₁ and I₂ is as follows
I₂ = I₁ cos²30
= I₀/2 x3/4
=3 I₀/8
Relation between I₃ and I₂ is as follows
I₃ = I₂ cos²30
= 3I₀ / 8 x 3/4
= 9 I₀ / 32
= 0 .28 I₀
In case of stack of 4 plates
angle between two plates = 90/4 = 22.5 degree
I₁ = I₀ /2
I₂ = I₁ cos²22.5
= I₀ /2 x .85
I₃ = I₂ cos²22.5
= I₀ /2 x .85 x .85
= .36 I₀
Answer:
0.4 Kilograms of flour
Explanation:
If you convert 400 grams into kilograms (400 ÷ 1,000), you would get 0.4 kilograms.
Chromosphere is the layer that is responsible for producing the sunlight
Answer:
Deflection at point C = 0.151 m
Explanation:
Central deflection due to uniformly distributed load w for simply supported beam
Central deflection due to point load P for simply supported beam
Here deflection
Deflection at point C = 0.151 m
