Study Notes
Young’s Double Slit Experiment
- Wavelength of light used: 5000 Å (Angstroms).
- Distance between slits: 0.2 mm.
- Screen distance from the slits: 2 meters.
- Position of 3rd maximum from the center of the screen can be determined using the formula for interference patterns.
Angular Momentum of Electron
- In Bohr's hydrogen atom, an electron with energy of –0.544 eV can have specific angular momentum values.
- Possible values include h, 2h, 7h, and 5h, with options provided to select the correct one.
Particle Decay
- A resting particle of mass 'M' decays into two particles of masses 'M' and '2M'.
- Conservation of momentum applies; the system must conserve total momentum before and after the decay.
Frequency and Interference
- Two tuning forks with frequencies 450 Hz and 454 Hz create beat frequencies.
- The interval between successive maximum intensities can be calculated based on the difference in frequencies.
Kinetic Theory of Gases
- Statement I: The mean free path of gas molecules is inversely proportional to the square of the molecular diameter.
- Statement II: The average kinetic energy of gas molecules is directly proportional to the absolute temperature.
- Evaluate the correctness of these statements to understand gas behavior.
Terminal Velocity of Sphere
- The terminal velocity of a sphere in a viscous medium is directly proportional to the square of its radius.
- Understanding the dynamics of motion in fluids is crucial for fields like fluid dynamics.
Focal Length of Lenses
- Cutting an equiconvex lens of focal length 15 cm has implications on the focal length of the individual halves.
- The understanding of focal length changes with modifications to optical components is essential in optics.
Object Placement and Image Formation
- An object of size 3.0 cm placed 14 cm in front of a concave lens with a focal length of 21 cm.
- Ratio of image size to object size impacts understanding of lens systems.
Chemical Reactions and Energy Change
- Various chemical reactions can be analyzed for changes in energy (ΔE).
- Specific reactions provided as options illustrate the relationship between reactants and products.
Reaction with Grignard Reagent
- The rate at which different alcohols react with Grignard reagents is compared.
- Understanding the mechanisms and rates of organic reactions is important in organic chemistry.
