The number of thermions emitted in a giv...

The number of thermions emitted in a given time increases 100 times as the temperature of the emitting surface is increased from `600 K to 800 K`. Find the work function of the emitter. Boltzmann constant `k = 8.62 xx 10^(-8) eV k^(-1)`.

Text Solution

AI Generated Solution

To solve the problem, we will use the Richardson-Dushman equation, which relates the number of thermions emitted to the temperature and work function of the emitter. ### Step-by-Step Solution: 1. **Identify Given Values:** - Initial temperature, \( T_1 = 600 \, K \) - Final temperature, \( T_2 = 800 \, K \) - The number of thermions emitted increases by a factor of 100, so \( n_2 = 100 n_1 \). ...
