Answer:
Explanation:
fringe separation or fringe width is directly proportional to wavelength .
Δ₁ / Δ₂ = wave length of first laser / wavelength of second laser
Δ₁ is fringe separation in first case and Δ₂ is fringe separation in second case.
putting the given values
632.8 / wavelength of second laser = 4.5 / 4.64
wavelength of second laser = 632.8 x (4.64 / 4.5)
= 652.48 nm
652 nm
Answer:
0.83999 m
0.20999 m
Explanation:
g = Acceleration due to gravity = 9.81 m/s² = a
s = 189 cm
When the time intervals are equal, if four drops are falling then we have 3 time intervals.
So, the time interval is
For second drop time is given by
Distance from second drop
Distance from second drop is 0.83999 m
Distance from third drop
Distance from third drop is 0.20999 m
Answer: the answer is c (think bc im on that too)
Explanation:
It'll remain constant because weight is what varies.
