Answer:
The length of the pendulum is 2.954 m.
Explanation:
Given;
period of the pendulum, T = 3.45 s
The period of the pendulum oscillation is given as;
where;
L is length of the pendulum
g is acceleration due to gravity on Earth = 9.8 m/s²
Therefore, the length of the pendulum is 2.954 m.
Answer:
t = 110.079 nm
Explanation:-
we know that
for constructive interference in thin film
2nt = (m + (1/2))λ
where, n is refractive index
for minimum thickness m =0
2nt = λ /2
thickness t = λ / 4n
Here
wavelength of light, λ = 612*10^{-9} m
refractive indices = 1.393
t = 110.03 nm
