Although we have discussed single-slit diffraction only for a slit, a similar result holds when light bends around a straight, t

QveST [7]

<h2>Width of hair is "1.96 10⁻⁵ m"</h2>

Explanation:

For this diffraction problem they tell us that it is equivalent to the diffraction of a single slit, which is explained by the equation
a sin θ =± m λ
Where the different temrs are: “a” the width of the hair, λ the wavelength, θ the angle from the center, m the order of diffraction, which is the number of bright rings (constructive diffraction)
We can see that the diffraction angle is missing, but we can find it by trigonometry, where L is the distance of the strand of hair to the observation screen and "y" is the perpendicular distance to the first minimum of intensity
L = 1.25 m 100 cm/1m = 125 cm
y = 5.06 cm
Tan θ = y/L
Tan θ = 5.06/12
θ = tan⁻¹ ( 0.0405)
θ = 2.32º
With this data we can continue analyzing the problem, they indicate that they measure the distance to the first dark strip, thus m = 1
a = m λ / sin θ
a = 1 633 10⁻⁹ 1.25/sin 2.3
a = 1.96 10⁻⁵ m
a = 0.0196 mm
Hence, "the width of the strand of hair is 1.96 10⁻⁵ m" is correct answer

<span>The gum is probably lodged in the right primary bronchus. The right primary bronchus is an airway directly connected to the right lung. Bronchi are primarily responsible for moving air into the lungs, so when Keri choked on the gum, the gum would have blocked the air passage way required to breathe.</span>

An object such as a piece of gold was cut into 2 halves, explain what would happen to its density?

nikdorinn [45]

Answer:

The density would stay the same.

Explanation:

The density would stay the same as density is an intensive property meaning it doesn't change based on the amount of matter that you have.
