Well, what's a well? Basically, to obtain water found in an aquifer, a well is a hole drilled into the earth. To pull water from the soil, a pipe and a pump are used and a screen filters out un Wells are drilled into the rock as deep as 1,000 feet to enter the water. ... Through a well pump, water flows through this casing. Above level, the well structure is closed off. From a pipe connected between the casing and a pressure tank (generally located in the basement of your house), the water then reaches your home.
I believe that if you shine a light in the front of a binocular, then the light would condense and be more pin-pointed while if you point it through the part where your eyes go the light would blow up. Either way, the light will be refracted once it travels through the lenses.
Answer:
0.66 degrees
Explanation:
The computation of the angle of the third dark interference is shown below:
The condition of the minima is
Path difference = (2n +1) × 
÷ 2
For third minima, n = 2
Now
xd ÷ D = (2 × 2 + 1) × ÷ 2
d tan Q_3 = 5 ÷ 2
tan Q_3 = 5 ÷ 2d
Q_3 = tan^-1 × (5 ÷2d)
= tan^-1 × (5 × 580 × 10^-9) ÷ (2 × 0.000125)
= 0.66 degrees
Answer: 133.33nm
Explanation: refractive index, n = real depth/apparent depth
Oil thickness= real depth = 200nm
Wavelength from under the water = apparent depth = a
n = real depth/a
1.5 = 200/ a
a = 200/ 1.5
a = 133.33nm
