Destructive interference in which waves cancel each other out is depicted in region X,Y and Z.
<u>Explanation:</u>
Interface is the particle property of light waves. When incident light beam is made to pass through holes, the waves will combine either constructively or destructively. Constructive interference means the waves having same phase will get added so they will increase in amplitude. While destructive interference means the waves combining have different phases like crests and troughs. So they undergo decrease or complete vanishing of amplitude.
When waves combine in constructive interference, they form bright white light and when they combine in destructive interference, they form dark black light. So the regions X, Y and Z are shown as dark black colors in the diagram, so these regions represent destructive interference in which waves cancel each other out.

Answer:
The concentration of an anthracene solution is
Explanation:
From the question we are told that
The incident beam is
The fluorescence intensity is
The length of the medium is b = 0.875 cm
The molar extinction coefficient is
The proportionality constant k = 0.30
According to Lambert law the Absorbance of the anthracene solution is mathematically represented as
Where
and A is the Absorbance
Substituting value
Generally beers law can be represented mathematically as
where c is the concentration of an anthracene solution
Making c the subject of the formula
Substituting 0.875 cm for length = b ,
We have
The empirical formula of the compound is C4H1.
An empirical formula represents the whole number ratio of various atoms present in a compound.
If the mass percent of various elements present in a compound is known, its empirical formula can be determined
We are given that a compound contains 4 mole C and 1 mole H.
Hence, the ratio of C: H is 4:1, which is already in the form of the simplest whole number.
Therefore, the empirical formula of the given compound is C4H1 and its molecular mass is 12 x 4 + 1 = 49.
