Compton used X-rays of 0.071nm wavelength. Some of the carbon鈥檚 electrons are too tightly bound to be stripped away by these X-rays, which accordingly interact essentially with the atom as a whole. In effect mein equation (3-8) is replaced by carbon鈥檚 atomic mass. Show that this explains why some X-rays of the incident wavelength were scattered at all angles.
An electron moving to the left at collides with an incoming photon moving to the right . After the collision, the electron is moving to the right at 0.6c and an outgoing photon moves to the left. What was the wavelength of the incoming photon?
A photon and an object of mass m have the same momentum p.
A low-intensity beam of light is sent toward a narrow single slit. On the far side, individual flashes are seen sporadically at detectors over a broad area that is orders of magnitude wider than the slit width. What aspects of the experiment suggest a wave nature for light, and what aspects suggest a particle nature?
According to Wien's Law, the wavelength of maximum thermal emission of electromagnetic energy from a body of temperature Tobeys
localid="1660036169367"
Show that this law follows from the spectral energy density obtained in Exercise 13. Obtain an expression that, when solved, would yield the wavelength at which this function is maximum. The transcendental equation cannot be solved exactly, so it is enough to show thatlocalid="1660036173306" solves it to a reasonable degree of precision.
