Study Notes
Variation
- Continuous Variation: Traits change gradually (e.g., height, weight).
- Discontinuous Variation: Traits are distinct (e.g., blood type, eye color).
- Genetic Factors: Variation comes from mutations and inheritance.
- Environmental Factors: Climate and lifestyle affect organism development.
- Mutations: Changes in DNA that create new traits.
Conservation of Mass
- Conservation of Mass Principle: Mass remains constant in chemical reactions.
- Chemical Equation: Shows reactants and products in a reaction.
- Reactants: Substances that change in a chemical reaction.
- Products: Substances formed from the reaction.
- Balancing Equations: Ensuring equal numbers of each atom on both sides of an equation.
Light Properties
- Speed of Light: Fastest in a vacuum (~300,000 km/s).
- Transmission: Light passing through a medium (e.g., glass).
- Refraction: Light bends when changing mediums.
- Specular Reflection: Light reflects off smooth surfaces, keeping image clear.
- Diffuse Reflection: Light scatters off rough surfaces, losing clarity.
- Angle of Incidence: Angle at which light hits a surface.
- Angle of Reflection: Angle at which light bounces off a surface.
- Colors of Light: White light contains all visible colors.
- Prism Effect: White light separates into ROYGBIV colors.
- Wavelength: Distance between successive peaks of a wave.
- Longest Wavelength: Red light.
- Shortest Wavelength: Violet light.
