Answer:
Explanation:
There is reflection ( two times ) from upper and lower surface of the film . In both cases , reflection is from low to high density medium so there is change in phase of 180 twice .
So for constructive interference
2μd = n λ₁ , d is thickness required , λ is wavelength n₁ is order of bright fringe
For destructive interference ( minimum light )
2μd = (2n+1) λ₂/2
n λ₁ =(2n+1) λ₂/2
(2n+1) / 2n = λ₁ / λ₂
= 650 / 505
= 5 / 4 ( approx )
2n = 4
n = 2
2μd = n λ₁
2 x 1.33 x d = 2 x 650 nm
d = 488.72 nm
Answer:
Ransom E. Olds was the person who invented assembly line.
The assembly line method was the very first method to be used in automotive sector and was the prototype for which Henry Ford industries had developed his own.
Explanation:
Ransom E. Olds was the person who invented assembly line.
The assembly line method was the very first method to be used in automotive sector and was the prototype for which Henry Ford industries had developed his own. Henry Ford enhanced the design of assembly line through the use of a conveyor system's running platforms.
The assembly line has always been recognized as among the 20th century's greatest inventions. It so profoundly influenced the industrialized world that industries that didn't adopt the trend quickly became extinct and was one of the primary factors that helped to incorporate the automobile into American society.
A hypothesis about what might happen in the lab might be 'oxygen will react with hydrogen to form water molecules'.
<h3>What is a hypothesis?</h3>
A hypothesis is a given explanation of a particular scientific question emerged by observing the real world.
Hypotheses are explanations that must be tested (either confirmed or rejected) by using the scientific method.
In conclusion, a hypothesis about what might happen in the lab might be 'oxygen will react with hydrogen to form water molecules'.
