22. 750 nm light is shone on a metallic surface with a work function of 1.5 eV. a) Find the energy and momentum of a single photon of the light. (2.7 x 10-19 J, 8.8 x 10-28 Ns) b) What is the kinetic energy of electrons emitted from the surface due to the photoelectric effect? (2.5 x 10-20 J) c) What is the de Broglie wavelength associated with these electrons? (3.1 nm)
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
Hi, please show full solutions and also explain how you get the answers in physics terms so it's understandable. The correct final answers are written beside too. This is one whole question to be answered, please. I can't post it separately since it's related. Thank you.
