A fringe width of 6 mm was produced for two slits separated by 1 mm apart. The screen is placed 10 m away. The wavelength of light used is x nm . The value of x to the nearest integer is ______.

Correct answer

0

Step-by-step solution

β = λ D d λ = β d D λ = 6 × 10 - 3 × 10 - 3 10 λ = 6 × 10 - 7   m = 600 × 10 - 9   m λ = 600   nm
