Answer:
The wavelength of the light is 487477.37 m.
Explanation:
Given that,
Spacing between the slits [tex]d= 4\times10^{6}\ m[/tex]
Angle = 7.00°
We need to calculate the wavelength
Using formula of wavelength
[tex]d\sin\theta=n\lambda[/tex]
Where, d = distance between the slits
n = order bright fringes
Put the value into the formula
[tex]\lambda=\dfrac{d\sin\theta}{n}[/tex]
[tex]\lambda=\dfrac{4\times10^{6}\times\sin7.00}{1}[/tex]
[tex]\lambda=487477.37\ m[/tex]
Hence, The wavelength of the light is 487477.37 m.
