Answer:
6.4 m/s
Explanation:
From the equation of continuity
A1V1=A2V2 where A1 and V1 are area and velocity of inlet respectively while A2 and V2 are the area and velocity of outlet respectively
where r1 and r2 are radius of inlet and outlet respectively
v1 is given as 1.6 m/s
Therefore
Answer:
The number of bright-dark fringe is 42
Solution:
As per the question:
Wavelength of light,
Length of the glass cell, x = 3.73 cm = 0.0373 m
Refractive index,
Now,
To calculate the bright-dark fringe shifts, we use the formula given below:
Now, substituting the appropriate values in the above formula:
≈ 42
