Answer:
wavelength of the laser light is 351nm
Explanation:
The split seperation is
d = 0.01 / 7735
= 1293nm
The angle of the first order maxima
θ = tan⁻¹ (0.488/1.73)
= 15.75°
we have,
[tex]sin \theta = \frac{m \lambda}{d} \\\lambda = \frac{d sin \theta}{m} \\\lambda = \frac{1293 \times sin15.75}{1} \\= 350.97nm[/tex]
≅ 351nm
wavelength of the laser light is 351nm
