HEAT, LIGHT, SOUND, ELECTRICITY (SCIENCE G-5)

- interacts with matter. It may be transmitted, reflected, absorbed , or refracted.

-         It also plays an important role in everyday life. It may be described in terms of wavelength, amplitude, and frequency.

TRANSPARENT MATERIALS

TRANSLUSLUCENT MATERIALS

OPAQUE MATERIALS

refers to the bouncing off of light as it hits the object’s surfaces.

is the bending of light due to a change in the medium it travels.

is the separation of white light into different colors. 

refers to the flow of energy from a high temperature object to a low temperature object.

is associated with the motion of the particles.

is produced by vibrating objects.

equilibrium

amplitude

crest

trough

wavelength

is produced by the vibration of the vocal cord.

is determined by the frequency of sound.

determines the sound’s loudness.

is an object that attracts metallic substances. It has two opposite ends, called poles.

is a magnet in which the magnetic field is produced by an electric current.

is the presence of electric charges that are stationary in an object.

is the flow of electrically charged particles from a source through a circuit.

is the path where electric current flows.

are materials that allow the passage of electrically charged particles freely.

are materials that do not allow the passage of electrically charged particles.

1.     Heat

2.     Magnetic effect (magnetic field)

where current moves along a single path.

wherein the electric current is divided by the number of paths through which it passes.
