Answer:
1.28 ×10^-4m
Explanation:
Interference is the superimposition of the wavefront. The superimposition causes bright and dark fringes.
The dark fringe is formed when the additional distance traveled is equal to the multiple wavelength integrals.
From the question, the parameters given are; Wavelength of the light,λ= 600nm, Distance of the screen (D) = 1.44m, order of the bright fringe (m) = 4, Distance of the 4 order fringe (y) = 2.7 cm.
Therefore, for the maximum bright fringe;
dy/D=mλ-----------------------------------------------------------------------------------------------------------------------(1)
Therefore, slotting in equation (1);
d×0.027/1.44=4×600×10^-9
d= 1.28×10^-4 m.
D
B
those are the correct answers
<h2>The baking of a Pizza be Categorize as Endothermic Process</h2>
The baking of a pizza should be categorized as an endothermic process because the dough absorbs heat. An endothermic process is a method that absorbs energy from its surroundings which is habitually in the form of energy.
It can be a biochemical process like solving the salt in water or just the melting of ice. Therefore, the dough absorbs heat and it is categorized as an endothermic process.
