Sample answer on Edu.

No, I do not agree with her. In order for sounds to be heard, the sound wave produced by a vibrating object needs to travel from the vibrating object to the ear through a medium.

What did you include in your answer? Check all that apply.

A vibrating object produces sound waves.

Energy needs to be transferred from the vibrating object to the ear through a medium.

Oduvanchick [21]

Answer:

1.6026299569\times 10^{-11}\ m

Explanation:

Grating constant

d=\dfrac{1}{6200}=0.000161\ cm=0.000161\times 10^{-2}\ m

Number of slits

N=3.14\times 6200=19468

Order

m=\dfrac{d}{\lambda}\\\Rightarrow m=\dfrac{0.000161\times 10^{-2}}{624\times 10^{-9}}\\\Rightarrow m\approx 2

At m = 1

\Delta\lambda=\dfrac{\lambda}{mN}\\\Rightarrow \Delta\lambda=\dfrac{624\times 10^{-9}}{1\times 19468}\\\Rightarrow \Delta\lambda=3.2052599137\times 10^{-11}\ m

At m = 2

\Delta\lambda=\dfrac{\lambda}{mN}\\\Rightarrow \Delta\lambda=\dfrac{624\times 10^{-9}}{2\times 19468}\\\Rightarrow \Delta\lambda=1.6026299569\times 10^{-11}\ m

The wavelengths can be close by 1.6026299569\times 10^{-11}\ m
