Sample Question 1
Outline the nature of electromagnetic waves.

Electromagnetic waves are produced by static charges.

Magnetic fields in electromagnetic waves are static and unchanging.

Consider an electric charge oscillating about a fixed position. It produces a varying electric field It produces a varying magnetic field (a moving charge is similar to a current) The two fields are perpendicular to each other

Only electric fields are present in electromagnetic waves.

Sample Question 2
Describe the different regions of the electromagnetic spectrum.

The regions of the electromagnetic spectrum are all identical.

See Image for table. Students should know the order of magnitude of the frequencies for the different regions, and should also be able to identify a possible source of the radiation in each region.

The electromagnetic spectrum only consists of visible light.

The regions of the electromagnetic spectrum have no scientific significance.

Sample Question 3
Describe the dispersion of EM Waves

The dispersion of EM waves is caused by the interference between electromagnetic fields

? Light passing from one medium to another is refracted. ? Degree of refraction (refractive index) depends on wavelength ? The differential refraction is called dispersion.

EM waves undergo dispersion when they change direction due to diffraction

Dispersion refers to the breaking down of EM waves into smaller particles
