Monochromatic light with wavelength 590 nm passes through a single slit 2. 30 ?m wide and 1. 90 m from a screen. Find the distan

aivan3 [116]

Answer:

The fringes are 4.7*10^-7 m apart, such that they are adjacent.

Explanation:

Using the formula for adjacent fringes given a single slit:

Δ $x=\frac{(Wavelength)(Distance between slit and screen)}{Width}$

Δ $x=\frac{(590/10^{9})(1.90) }{(2.30)}$

Δ $x=0.000000487 m$

Hope this helps!

An irregularly shaped rock is placed in 50 mL of water. The new reading in the container is now 74.2 mL. If the mass of the rock

cricket20 [7]

Taking into account the definition of density, the density of the rock is 3.6583 g/mL.

<h3>Definition of density</h3>

Density is defined as the property that matter has to compress into a given space.

In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.

The expression for the calculation of density is:

density= mass÷ volume

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

<h3>Density of the rock</h3>

In this case, you know that:
