Thanks. So for ejecting an electron, the energy of the photon determines if the electron can be ejected. And the intensity is the amount of photons (if monochromatic) of the same energy hitting the atom/surface. With a light beam, increasing frequency or decreasing wavelength increases energy...

Ok. So this question is the reason I am so confused. A certain metal plate is completely illuminated by a monochromatic light source. Which would increase the number of electrons ejected from the surface of the metal. 1. increase the intensity of light source 2. increase the frequency of...

So I know light is wave-particle. What is the wave part (interference,dispersion,diffraction)? What is the particle part(refraction, reflection, E=hf)? Also what is the difference between the intensity of light and the energy of light? One more, in my book it says doubling frequency would not...
