$2p\rightarrow 1s$

Explanation:

The energy of transition of $3p\rightarrow 1s$ is greater as compared to $2p\rightarrow 1s$ as there are more quantum levels which leads to more energy.

Also, considering the expression as:

$E=\frac {h\times c}{\lambda}$

Where,

h is Plank's constant having value $6.626\times 10^{-34}\ Js$

c is the speed of light having value $3\times 10^8\ m/s$

$\lambda$ is the wavelength

Wavelength is inversely proportional to Energy. Thus, the transition which has lower energy corresponds to higher wavelength.

Thus, answer - $2p\rightarrow 1s$

Inertia is based only on an object’s mass.

Explanation:

Any physical object's resistance towards any change in its velocity is known as inertia.

Therefore, more is the mass of an object, the more inertia will be there.

Thus, we can conclude that inertia is based only on an object’s mass and not on velocity.
