Chapter 38: Q.67 (page 1117)

I Two hydrogen atoms collide head-on. The collision brings both atoms to a halt. Immediately after the collision, both atoms emit a $121.6 nm$ photon. What was the spec of each atom just before the collision?

Short Answer

Expert verified

The short solution to the energy problem is

$v = 44246 \frac{m}{s}$

Step by step solution

Step: 1 Given information

The given of atoms emits a $121.6 nm$ photon.

Calculation

We can begin by focusing on energy conservation.

$E_{photon} = E_{k} \frac{h c}{λ} = \frac{m v^{2}}{2} v = \sqrt{\frac{2 h c}{λ m}} v = \sqrt{\frac{26.63 \cdot 10^{- 34} \cdot 3 \cdot 10^{8}}{121.6 \cdot 10^{- 9} \cdot 1.67 \cdot 10^{- 27}}} v = 44246 \frac{m}{s}$
