Validating the Bohr's Model
- Higher is the atomic number, more is the wavelength
- Higher is the atomic number, less is the wavelength
- Can't be answered using Rydberg's Formula
- Wavelength is independent of the atomic number
In which of the following systems will the wavelength corresponding to n = 2 to n = 1 be minimum?
Singly ionized helium
Doubly ionized lithium
The above picture depicts the possible transitions of electron in Bohr's atomic model.
Match the transition lines to corresponding series.

- Tn ∝1n2, rn ∝n2
- Tn independent of n, rn ∝ n
- Tn ∝1n, rn ∝n
- Tn ∝1n, rn ∝n2
Suppose in an imaginary world the angular momentum is quantized to be even intergral multiples of h2π. What is the longest possible wavelength emitted by hydrogen atoms in visible range in such a world according to Bohr's model ?
A hydrogen atom emits ultraviolet radition of wavelen gth 102.5 nm. What are the quantum numbers of the states involved in the transition ?
- n - 5 to n -4
- n - 4 to n - 3
- n - 3 to n - 2
