It’s gonna take it 5 cm to reach the distance
Answer:
θ = 14.45º = 0.252 rad
Explanation:
The expression that describes the phenomenon of diffraction is
a sin θ = m λ
Where a is the width of the exit opening in this case the width of the door, Lam is the wavelength, m the diffraction order for destructive interference,
Let's use the relationship between the speed of the wave is the producer of its frequency by the wavelength
v = λ f
λ = v / f
λ = 344/1220
λ = 0.282 m
sin θ = m λ / a
For the first destructive interference m = 1
sin θ = 1 0.282 /1.13
sin θ = 0.24956
θ = sin-1 (0.24956)
θ = 14.45º
We pass radians
θ = 14.45 (pi rad / 180º) = 0.252 rad
Hello!
I believe its A. wrist flexors but im not exactly sure because it might be B. wrist extensors.
