Answer:
it is accepted all over the world
it is more reliable than other kinds of measuring system
B is the answer!!!!!!!!!!!!!
As the slit width increases, the diffraction pattern gets narrower and vice versa.
<h3>Relationship between width and diffraction pattern</h3>
The increase in silt width leads to the narrowing of diffraction pattern of the light because the increase of width reduces the space for the passing of light wave.
So we can conclude that as the slit width increases, the diffraction pattern gets narrower and vice versa.

The equation of the wave travelling along the +x-axis is y = 0.02 sin (880π/330 x – 880 πt)
<u>Explanation:</u>
Given data
Amplitude 0.02 m , Frequency= 440 Hz ,Speed = 330 m/s
The equation format is written as,
y = A sin ( k x – ω t)
We need the value of A, k, x -ω t
<u>1. Find the k value</u>
v = f ×λ
330 = 440×λ
k = 2π×λ
k = 880 π /330 m-1
440 ×2π = w
<u>2. Find the ω value</u>
f×2π =ω
ω
= 880 π s-1
<u>3. Find the A value</u>
we get A value from the given data
A = 0.02 m
By the formula,
y = A sin ( k x – ω t)
Substitute the values we get the equation,
y = 0.02 sin (880π/330 x – 880 πt)
The equation of the wave travelling along the +x-axis is y = 0.02 sin (880π/330 x – 880 πt)
