The electromagnetic spectrum

Transverse waves consisting of changing electric fields

An _______ in a region of space exerts electric forces on charged particles. These are produced by electrically charged particles

• magnetic field

• electric field

• electromagnetic waves

• electron

Electromagnetic waves are produced when an electric charge vibrates or accelerates

• True

• False

The transfer of energy by electromagnetic waves traveling through matter or across space is called

• electric field

• magnetic field

• electromagnetic radiation

• electric charge

The speed of light (c) is

• 3x10^8 m/s

• 5x10^8m/s

• 5x10^-8m/s

• 3x10^-8m/s

This experiment helped to calculate the speed of light and electromagnetic waves

• Young's experiment

• Herschel's experiment

• Michelson's experiment

• None of them

Electromagnetic radiation behaves sometimes like a wave and sometimes like a stream of particles

• True

• False

Light consists in packets of electromagnetic energy called

• electrons

• photons

• protons

• waves

Rate at which a wave's energy flows through a given unit of area

• Amplitude

• Wavelength

• cycle

• Intensity

The full range of frequencies of electromagnetic radiation is called
