Based on equation E = –2.178 × 10–18J, $\frac{{\mathrm{Z}}^{2}}{{\mathrm{n}}^{2}}$ certain conclusions are written. Which of them is not correct ?
1. Larger the value of n, larger is the orbit radius.
2. Equation can be used to calculate the change in energy when the electron changes orbit.
3. For n = 1, the electron has a more negative energy than it does for n = 6 which means that the electron is more loosely bound in the smallest allowed orbit.
4. The negative sign in equation simply means that the energy of electron bound to the nucleus is lower than what it would be if the electrons were at an infinite distance from the nucleus.

The energies E1 and E2 of two radiations are 25 eV and 50 eV respectively. The relation between their wavelenghs i.e., ${\mathrm{\lambda }}_{1}$ and ${\mathrm{\lambda }}_{2}$ will be

1.  ${\mathrm{\lambda }}_{1}=2{\mathrm{\lambda }}_{2}$

2.  ${\mathrm{\lambda }}_{1}=4{\mathrm{\lambda }}_{2}$

3.  ${\mathrm{\lambda }}_{1}=\frac{1}{2}{\mathrm{\lambda }}_{2}$
