Question 287

A pipe open at both ends has fundamental frequency $f$. It is dipped to half its length in water. The new fundamental frequency is:

$\dfrac{3f}{2}$
2f
$\dfrac{f}{2}$
f✔️

Correct Answer Logic:

Original open pipe of length $L$: $f=\frac{v}{2L}$. When dipped to half length, remaining open length $=L/2$ acts as a closed pipe (one end closed by water). Fundamental of closed pipe: $f'=\frac{v}{4(L/2)}=\frac{v}{2L}=f$. The frequency remains $f$.

Chemistry QUESTION #7349

Question 299

The energy of the second Bohr orbit of hydrogen atom is $-328$ kJ/mol. Based on this, the energy of the fourth Bohr orbit will be:

$-41$ kJ/mol
$-1312$ kJ/mol
$-164$ kJ/mol
$-82$ kJ/mol✔️

Correct Answer Logic:

Bohr's energy formula: $E_n = \dfrac{E_1}{n^2}$

Given $E_2 = -328$ kJ/mol, so $E_1 = -328 imes 4 = -1312$ kJ/mol.

$E_4 = \dfrac{-1312}{16} = -82$ kJ/mol

Key point: as $n$ increases, energy becomes less negative — outer orbits are less tightly bound.
