Answer:
Explanation:
The diffraction pattern is given as
Sinθ = mλ/ω
Where m=1,2,3,4....
Now, when m=1
Sinθ = λ/ω
Then,
ω = λ/Sinθ
The width of the central bright fringe is given as
y=2Ltanθ. From trigonometric
Then,
θ=arctan(y/2L)
Given that,
y=0.052m
L=0.55m
θ=arctan(0.052/2×0.55)
θ=arctan(0.0473)
θ=2.71°
Substituting this into
ω = λ/Sinθ
Since λ=544nm=544×10^-9m
Then,
ω = 544×10^-9/Si.2.71
ω = 1.15×10^-5m.

Explanation:
The speed of a wave is given by:
where
v is the speed of the wave
f is the frequency
is the wavelength
For the wave in this problem, we have
f = 4 Hz is the frequency
is the wavelength
So, the speed of the wave is
