Why is there an upward force on objects in water?

If you'r referring to some objects, it means that the mass of the object is less than the water so it floats. If the mass of an object is greater than the mass of the water, it will sink. Compare it to a balloon, helium makes it rise, while normal air makes it sink.

You perform a double‑slit experiment in order to measure the wavelength of the new laser that you received for your birthday. Yo

Vitek1552 [10]

Answer:

λ = 5.734 x 10⁻⁷ m = 573.4 nm

Explanation:

The formula of the Young's Double Slit experiment is given as follows:

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

where,

λ = wavelength = ?

L = distance between screen and slits = 8.61 m

d = slit spacing = 1.09 mm = 0.00109 m

Δx = distance between consecutive bright fringes = $\frac{4.53\ cm}{10}$ = 0.00453 m

Therefore,

$\lambda = \frac{(0.00453\ m)(0.00109\ m)}{8.61\ m}$

<u>λ = 5.734 x 10⁻⁷ m = 573.4 nm</u>
