Answer:
Y = 17.75 x 10⁻³ m = 17.75 mm
Explanation:
Using Young's Double Slit formula below:
where,
Y = fringe separation = ?
λ = wavelength = 568 nm = 5.68 x 10⁻⁷ m
L = distance between slits and screen = 3.5 m
d = slit separation = 0.112 mm = 1.12 x 10⁻⁴ m
Therefore,
<u>Y = 17.75 x 10⁻³ m = 17.75 mm</u>
Answer: 276 days
Explanation:
This problem can be solved using the Radioactive Half Life Formula:
(1)
Where:
is the final amount of the material
is the initial amount of the material
is the time elapsed
is the half life of polonium-210
Knowing this, let's substitute the values and find from (1):
(2)
(3)
(4)
Applying natural logarithm in both sides:
(5)
(6)
