EM Waves

What is a wave?

• a disturbance that transfers energy as it propagates from one region of the system to the other.

• it is the material where waves travel

• it is the position of maximum upward displacement from the equilibrium position

• a disturbance that carries matter from one place to another.

Which of the following is not a classification of a wave?

• Longitudinal waves

• Sound waves

• Electromagnetic waves

• Mechanical waves

Waves in which the medium moves at right angles to the direction of the wave?

• Longitudinal waves

• Transverse waves

• Electromagnetic waves

• Mechanical waves

It refers to the maximum distance of a particle with respect to the equilibrium position.

• Amplitude

• Wavelength

• Frequency

• Period

It is the position of maximum upward displacement from the equilibrium position in a wave

• Crest

• Trough

• Frequency

• Wave speed

It depends on the medium in which the wave is traveling. It varies in solids, liquids and gases.

• Frequency

• Wave speed

• Amplitude

• Wavelength

It refers to the distance between two successive identical parts of the wave.

• Wave speed

• Amplitude

• Wavelength

• Frequency

These are waves that do not require a medium of propagation because these waves can propagate in a vacuum

• Longitudinal waves

• Sound waves

• Electromagnetic waves

• Mechanical waves

It is the arrangement of electromagnetic waves according to photon energy, wave frequency, and wavelength.

• Electromagnetic radiation

• Electromagnetic spectrum

• Electromagnetic wheel

• Electromagnetic wave

What two waves lie at both ends of the visible spectrum?

• Radio waves and X-rays

• Infrared and Ultra-violet ray

• Radios waves and Microwaves

• Radio waves and Gamma rays
