1. If light with a frequency below the cutoff frequency for a certain metal hits that metal: Question 1 options: electrons will be ejected after the intensity of the light reaches a certain value no electrons will be ejected electrons will be ejected, but will fall back to the metal the light will be re-radiated by the metal I don't know. 2. One electron-volt is equivalent to Question 2 options: 1 J 1 V 1.6 x 10^-19 J 1.6 x...

KURSVLOEBEUR Question 4 [20 marks] (a) What particular aspect of the Rayleigh-Jeans Law, the classical theory of blackbody radiation, caused it to fail to explain the blackbody radiation spectrum? (b) What aspect of the Boltzmann probability distribution used in formulating Planck's Law of blackbody radiation allows it to avoid the problem that caused the classical model to "crash and burn" i.e. not match experiment? (c) In a low energy electron diffraction (LEED) experiment, 62 eV electrons are scattered from the...
