Concept explainers

Compton effect

The incoming photons' energy must be in the range of an X-ray frequency to generate the Compton effect. The electron does not lose enough energy that reduces the wavelength of scattered photons towards the visible spectrum. As a result, with visible lights, the Compton effect is missing.

Recoil Velocity

The amount of backward thrust or force experienced by a person when he/she shoots a gun in the forward direction is called recoil velocity. This phenomenon always follows the law of conservation of linear momentum.

Consider a laser pen. Construct a problem in which youcalculate the number of photons per second emitted by thepen. Among the things to be considered are the laser pen’swavelength and power output. Your instructor may also wishfor you to determine the minimum diffraction spreading in thebeam and the number of photons per square centimeter thepen can project at some large distance. In this latter case,you will also need to consider the output size of the laserbeam, the distance to the object being illuminated, and anyabsorption or scattering along the way.
