Understand what conclusions about a new theory of the structure of matter and light can be drawn from the following experimental results: the photoelectric effect and the fact that atomic spectra contain discrete, very sharp lines.
Homework Answers
According to photoelectric effect it is the phenomenon which explains the emission of electronic from the matter when it is hit by the photon by absorbing the energy from it . This process continues till the electron gets required energy to leave the surface of matter.
It explains that similar to the light matter has also dual nature
Wave and particle nature of light.
So any matter can act as both wave and particle.
The fact that atomic spectra is discrete but continuous is due to electron of an atom absorbs and emits energy when it jumps from higher energy level to lower energy level and lower energy level to higher energy level.
The energy of these electrons are discrete hence hence the spectra is discrete and sharp lines.

To understand the experiment that led to the discovery of the photoelectric effect.In 1887, Heinrich Hertz investigated the phenomenon of light striking a metal surface, causing the ejection of electrons from the metal. The classical theory of electromagnetism predicted that the energy of the electrons ejected should have been proportional to the intensity of the light. However, Hertz observed that the energy of the electrons was independent of the intensity of the light. Furthermore, for low enough frequencies, no electrons...

Capital Structure Theory Modern capital structure theory began in 1958 when Professors Modigliani and Miller (MM) published a paper that proved under a restrictive set of assumptions that a firm's value is unaffected by its capital structure. By indicating the conditions under which capital structure is irrelevant, they provided dues about what is required to make capital structure relevant and impact a firm's value. In 1963 they wrote a paper that included the impact of corporate taxes on capital structure....
