Answer:
The minimum thickness of the oil is 77.55 nm
Explanation:
Given:
Refractive index of oil
Refractive index of water
Wavelength of light m
From the equation of thin film interference,
The minimum thickness is given by,
Where ,
thickness
Here we have to find minimum thickness so we use
m
nm
Therefore, the minimum thickness of the oil is 77.55 nm
Answer:
The Height is H = 70.02 m
Explanation:
We are given that the
Initial length is = =
from what we are told in the question the circumference of the circle is =
This means that the Radius would be :
Let C denote the circumference
So
=>
We are told that 1-meter bar of steel that increases its temperature by 1 degree C will expand meters
Hence
The final length would be
Where T is the change in temperature is the Coefficient of linear expansion for steel
let denote the final length
So
Now the Height is mathematically represented as
