An instructor wishes to determine the wavelength of the light in a laser beam. To do so, she directs the beam toward a partition
Rus_ich [418]

Answer:

λ = 623.2 nm

Explanation:

We are given;

separation distance; d = 0.195 mm = 0.195 × 10^(-3) m

interference pattern distance; D = 4.85 m

Width of two adjacent bright interference; w = 1.55 cm = 1.55 × 10^(-2) m

Formula for fringe width is given as;

w = λD/d

Where λ is wavelength

Thus;

λ = dw/D

λ = (0.195 × 10^(-3) × 1.55 × 10^(-2))/4.85

λ = 0.0000006232 m

Converting to nm gives;

λ = 623.2 nm

How much energy does the electron have initially in the n=4 excited state?what is the change in energy if the electron from part
Ierofanga [76]
What it looks to be that you found in A was the "initial"...b/c the question asks: 
<span>"how much energy does the electron have 'initially' in the n=4 excited state?" </span>

<span>"final" would be where it 'finally' ends up at, ie. its last stop...as for this question...the 'ground state' as in its lowest energy level. </span>

The answer comes to: <span>−1.36×10^−19 J</span>


You use the same equation for the second part as for part a. 
<span>just have to subract the 2 as in the only diff for part 2 is that you use 1squared rather than 4squared & subract "final -initial" & you should get -2.05*10^-18 as your answer. </span>

Which sequence of coefficients will balance the following equation Ca (s) O2 (g) 2CaO (s)
xxTIMURxx [149]

 Ca(s) + O₂(g)→ 2 CaO  (s)

The  sequence   of coefficient  that  will  balance the  above equation is

 2,1 ,2


Explanation

Coefficient  is the number in front  of  the formulas.

When balancing  the equation  the  number of atoms  in reactant side  must be  equal  to  number  of atoms  in product  side.

The sequence  that   balance the equation  above  is 2,1,2   therefore  the balanced  equation is as below.

2Ca (s)  +  O₂ → 2CaO (s)
