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

How do humpback whales survive and their population increasing
Nookie1986 [14]

Answer:

After being hunted almost to extinction, the humpback whale population has rebounded dramatically. Rapidly melting Antarctica ice poses a threat to coastal cities, but there is at least one species that is benefiting: Humpback whales are flourishing these days, due to an abundance of krill.

Pre-hunting population size may have been as many as 200,000-300,000 whales. They were estimated to number around 2,300 in 1998 and to be increasing between 2.4-8.4% per year. The IWC is undertaking an assessment of Antarctic blue whales at present.
