Answer:
its b nasa and every other space obsessed place has done all of that
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.
The pOH scale is similar to the pH scale in that a pOH of 7 is indicative of a neutral solution. A basic solution has a pOH less than 7, while an acidic solution has a pOH of greater than 7
<h3>What is
pOH scale?</h3>
Based on the relative concentration of hydrogen and hydroxyl ions, the pH and pOH scales are used primarily in chemistry, biology, and soil science to describe and measure the acidity and basicity of neutral, acidic, and basic solutions in water.
The terms pH and pOH scale are frequently used and crucial for determining the chemical, biological, and soil health by converting the values of hydrogen or hydroxyl ion concentrations or by utilizing pH paper and meters.
The pH scale or chart, which measures the concentration of hydrogen and hydroxyl ions in acidic and alkaline solutions, was initially developed by Sorensen.
