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 = ?
Shiny, ductility, malleability are some
Answer:
Fundamental frequency is 70.12 m
Explanation:
For an open organ pipe, the fundamental frequency is given by :

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,

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