Electromagnetic Waves Electric Magnetic Fields

Identify the fields produced by a moving charged particle.

• Both an electric field and a magnetic field will be produced.

• Neither a magnetic field nor an electric field will be produced.

• A magnetic field, but no electric field will be produced.

• only the electric field, but no magnetic field will be produced.

In an electromagnetic wave, how are the magnetic field, the electric field, and the direction of propagation oriented to each other?

• All three are parallel to each other and are along the x-axis.

• All three are mutually perpendicular to each other.

• The electric field and magnetic fields are parallel to each other and perpendicular to the direction of propagation.

• The magnetic field and direction of propagation are parallel to each other along the y-axis and perpendicular to the electric field.

Where do radio waves fall on the electromagnetic spectrum? Radio waves-

• have the same wavelengths as visible light.

• Radio waves fall on the high-frequency side of visible light.

• fall on the short-wavelength side of visible light.

• fall on the low-frequency side of visible light.

X-rays carry more energy than visible light. Compare the frequencies and wavelengths of these two types of EM radiation. Visible light has-

• higher frequencies and shorter wavelengths than X-rays.

• lower frequencies and shorter wavelengths than X-rays.

• higher frequencies and longer wavelengths than X-rays.

• lower frequencies and longer wavelengths than X-rays.

How does wavelength change as frequency increases across the EM spectrum?

• The wavelength increases.

• The wavelength first increases and then decrease.

• The wavelength first decreases and then increases.

• The wavelength decreases.

Why are X-rays used in imaging of broken bones, rather than radio waves?

• X-rays have higher penetrating energy than radio waves.

• X-Rays have lower penetrating energy than radio waves.

• X-Rays have a lower frequency range than radio waves.

• X-Rays have longer wavelengths than radio waves.
