polarized light

. The light that passes through vibrates in only one direction and is called

The energy that is transferred through space by electromagnetic waves.

Electromagnetic Radiation

A transverse wave that transfers electric and magnetic energy.

Electromagnetic wave

Sometimes light behaves like a stream of particles. Light causes electrons to move which causes an electric current to flow.

Particle Model of Light

Sometimes light can cause an electron to move so much that the electron gets knocked out of the substance.

Photoelectric effect

False

True or False-Consists of both vibrating electric and magnetic fields positioned at right angles to each other and to the direction of the wave and that move around space at the speed of light

True

True or False-Electromagnetic waves do not carry energy by causing matter to vibrate, and so electromagnetic waves can travel in a vacuum without a medium.

true

True or False-Electrons are charged particles that can produce electric and magnetic fields.

true

True or False-Electrons move back and forth, which causes a vibration

True

True or False-Light moves in all directions

True

True or False-Only some of this light can pass through a polarizing filter

False

True or False-The speed of light is about 300,000 kilometers per second

False

True or False-This change in speed and direction of electrons is not the energy source of all electromagnetic waves

False

True or False-only light traveling without slits can pass through

Light travels as waves that travel in all directions
