Light shines through a single slit whose width is 5.6 × 10-4 m. A diffraction pattern is formed on a flat screen located 4.0 m a
Mrac [35]

Answer:

462 nm

Explanation:

Given: width of the slit, d = 5.6 × 10⁻⁴ m

Distance of the screen, D = 4.0 m

Fringe width, β = 3.3 mm = 3.3 × 10⁻³ m

First dark fringe means n =1

Wavelength of the light, λ = ?

\beta = \frac{\lambda D}{d}\\ \Rightarrow \lambda = \frac{d \beta}{D} =\frac{5.6\times 10^{-4} \times 3.3 \times 10^{-3}}{4.0} = 4.62 \times 10^{-7}m = 462 nm

An open organ pipe is 2.46 m long, and the speed of the air in the pipe is 345 m/s.
lukranit [14]

Answer:

Fundamental frequency is 70.12 m

Explanation:

For an open organ pipe, the fundamental frequency is given by :

f=\dfrac{nv}{2l}

n = 1 for fundamental frequency

v is speed of sound in air, v = 345 m/s

l is length of open organ pipe, l = 2.46 m

Substituting values in above formula. So,

f=\dfrac{1\times 345}{2\times 2.46}\\\\f=70.12\ Hz

So, the fundamental frequency of this pipe is 70.12 m.

Find the time th it takes the projectile to reach its maximum height h. express th in terms of v0, ?, and g (the magnitude of th
fenix001 [56]
The derivative of
  h(t) = (-g/2)t² +v0·t + h0
is
  h'(t) = -gt +v0

This is zero at the maximum height, so the time can be found as
  0 = -gt +v0
  gt = v0
  t = v0/g
