101 حقيقة في الفيزياء

Modern Physics




69- The particle behavior of light is proven by the photoelectric effect.
70- A photon is a particle of light {wave packet}.
71- Large objects have very short wavelengths when moving and thus can not be observed behaving as a wave. (DeBroglie Waves)
72-All electromagnetic waves originate from accelerating charged particles.
73- The frequency of a light wave determines its energy (E = hf).
74- The lowest energy state of a atom is called the ground state.
75- Increasing light frequency increases the kinetic energy of the emitted photo-electrons.
76- As the threshold frequency increase for a photo-cell (photo emissive material) the work function also increases.
77- Increasing light intensity increases the number of emitted photo-electrons but not their KE.
