Answer:
False
Explanation:
All the lanthanides are not radioactive in nature. Just one of the lanthanides are radioactive.
- The lanthanides belong to the f-block on the periodic table
- Only Promethium in this group are radioactive in nature.
- Other elements in the lanthanide series might have radioactive isotopes.
Answer:
Δx = 2.76 x 10⁻³ m = 2.76 mm
Explanation:
The distance between any two consecutive dark or consecutive bright fringes is given by:
Δx = λL/d
where,
Δx = distance between first and second dark fringe = ?
λ = wavelength of light = 546.1 nm = 546.1 x 10⁻⁹ m
L = distance between slits = 1.35 m
d = slit separation = 0.267 mm = 2.67 x 10⁻⁴ m
Therefore,
Δx = (546.1 x 10⁻⁹ m)(1.35 m)/(2.67 x 10⁻⁴ m)
<u>Δx = 2.76 x 10⁻³ m = 2.76 mm</u>
