Answer:

λ = 1.388 x 10⁻⁶ m = 1388 nm

Explanation:

We can use the Young's Double Slit experiment formula here to solve this numerical:

$\Delta x = \frac{\lambda L}{d} \\\\\lambda = \frac{\Delta x d}{L}\\$

where,

λ = wavelength = ?

Δx = distance between adjacent bright fringes = 1.62 cm = 0.0162 m

d = slit separation = 0.24 mm = 0.00024 m

L = distance from screen to slits = 2.8 m

Therefore,

$\lambda = \frac{(0.0162\ m)(0.00024\ m)}{2.8\ m} \\$

Answer:

11.87

Explanation:

final velocity^2= initial velocity ^2+ 2* Acceleration* distance

Final Velocity^2= 9*9+2*1.5.20

final velocity^2 = 141

final velocity = 11.87
