Document Summary
Lower energy inferred just bending the molecules. Radio waves have minor affects at nuclear level (mri) Energy and frequency are directly related by plunk"s constant. If you heat a blackbody, you can make it emit energy and glow. Ows with a speci c band of frequencies. White hot is hotter than red hot. Brightness is our measure of the intensity of the wave. If you have light at a speci c frequency, you know the energy carried. Light behaves both as a particle and a wave. The particles of light get more densely packed, the more intense. When light passes through slits, a pattern appears. The particles would hit with the most probability in the brightest spots (higher intensity) Doesn"t matter how intense the light is for electron emission. Energy comes from collision between photons and electron. Esubkin = hv - esub0 = hv = hvsub0.
