Study Notes
- Hadrons and leptons are two main groups of particles in physics
- Leptons include the electron, muon, and neutrino, with an electron number of one
- Antileptons have an electron number of minus one
- Hadrons consist of baryons (three quarks) and mesons (quark-antiquark pairs)
- Quark flavors include up, down, and strange with specific charges
- Barions have a baryon number of plus a third
- Exchange particles like photons mediate the electromagnetic force
- Weak nuclear force involves W+, W-, or Z0 bosons as exchange particles
- Strong nuclear force acts on hadrons through pions or gluons
- Conservation laws include charge, baryon number, and lepton number
- Beta decay involves the transformation of a neutron into a proton
- Radiation types include alpha, beta, and gamma emissions
- Defraction patterns demonstrate the wave nature of particles
- Ohm's law relates voltage, current, and resistance in a circuit
- Resistance can be omic (constant) or non-omic (changing)
- Metals have changing resistance due to collisions between free electrons and ions- Resistance increases when ions vibrate more due to frequent collisions when current passes through a material.
- Diode allows current to flow in one direction only, with high resistance in one direction and low resistance in the other.
- Light Emitting Diodes (LEDs) emit light and act as diodes in circuits.
- Superconductors have zero resistance below the critical temperature, needing cooling to reach this point.
- Resistivity is the resistance of a cube of unit length sides of a material, measured in ohm meters.
- Resistivity can be calculated using the formula ρ = RA/L, where ρ is resistivity, R is resistance, A is area, and L is length.
- In series circuits, total potential difference is shared, current remains the same, and resistance adds up.
- In parallel circuits, potential difference across branches is the same, current is shared, and total resistance decreases.
- Total internal resistance of batteries affects terminal potential difference available to the circuit.
- Optic fibers work by using cladding to allow total internal reflection for efficient light transmission.- Young's double slit equation W = λd/s calculates the fringe spacing between bright or dark fringes, where d is the slit-to-screen distance and s is the slit separation.
- When using sound waves instead of light in Young's double slit experiment, walking through Maxima and Minima points causes volume fluctuations due to interference patterns.
- Single slit diffraction results in a pattern where the central max is wider and the intensity falls away quicker compared to double slit interference patterns.
- Coherent light from a laser is preferred for experiments due to its monochromatic nature, providing well-defined fringes, unlike white light that splits into colors due to varying wavelengths.
- Gratings with small lines separated by spacing "d" result in constructive interference only at specific points called orders, represented accurately by the equation nλ = d sin(θ).
- Newton's laws cover various aspects of motion, with the first law stating objects remain in constant motion or rest without a resultant force acting on them.
- Newton's second law relates unbalanced forces to acceleration, while the third law explains equal and opposite reaction forces for every action force.
- Momentum is mass times velocity, always conserved in collisions, while kinetic energy may not be conserved in inelastic collisions.
- Impulse is the change in momentum over time, with force equal to the rate of change of momentum.
- Torque is a turning force around a pivot, calculated as force times distance to the pivot and relies on perpendicular force and distance components for accurate calculation.
