PRESENTATION OUTLINE
Conduction
- Heat can also be transferred from one object to another, or from one molecule to another through the process of conduction.
- Conduction transfers heat within a body or between two bodies that are touching.
- Conduction occurs in solids, liquids, or gases that are at rest.
Convection
- The final way that heat is transferred from one place to another is convection.
- Convection takes place when heated molecules move from one place to another, taking the heat with them.
- Convection is common in both the atmosphere as well as in the oceans.
Radiation
- Radiation is energy that comes from a source and travels through space.
- Electromagnetic waves that directly transport ENERGY through space.
- Sunlight is a form of radiation that is radiated through space to our planet without the aid of fluids or solids.
Reflection
- Reflection occurs when light bounces off objects.
- Refraction occurs because light bends.
- The curved surface/surfaces of a lens bends the light
Scattering
- A form of scattering in which light in the form of propagating energy is scattered.
- Light scattering can be thought of as the deflection of a ray from a straight path, for example by irregularities in the propagation medium, particles, or in the interface between two media.
- Scattering of light depends on the wavelength or frequency of the light being scattered.
Absorption
- Absorption, in wave motion, the transfer of the energy of a wave to matter as the wave passes through it.
- The process by which substances are taken into the tissues of organisms is called absorption.
