Quiz10-RF Fundamentals

"All EM waves travel at the same speed, the faster it oscillates the shorter the wavelength. And a longer wavelength implies a slower frequency."

• True

• False

Not strictly defined but RF can range from 1 kHz to 300 GHz.

• True

• False

Radio frequency (RF) refers to energy whose frequency is high enough to radiate into free space.

• True

• False

RF energy is consider non-ionizing rays when it cannot break apart atoms or molecules.

• True

• False

Modulation is defined as the process of converting data into radio waves by adding information to an electronic or optical carrier signal.

• True

• False

This type of loss occurs as the signal travels through space without any other effects attenuating the signal. it will still diminish as it spreads out.

• Diffraction loss

• Free space loss

• Absorption loss

• Multipath loss

"Based on the speed of light formula, wavelength can be determined by"

• Speed of light divided by frequency

• Speed of light multiply by frequency

• Frequency divided by speed of light

• Frequency multiplied by speed of light
