• B. Frequency
• C. Velocity
• D. Time

Answer 1

Answer: (A), (B), (C)

The correct options are
A Wavelength
B Frequency
C Velocity

Electromagnetic waves are transverse waves, similar to water waves in the ocean or the waves seen on a guitar string. The characteristics of electromagnetic waves are:

• Wavelength: The entire electromagnetic spectrum, from the lowest to the highest frequency, includes all radio waves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
• Frequency: The frequency of any waveform equals velocity divided by wavelength. The unit of measurement is Hertz.
• Velocity: The velocity of electromagnetic waves in a vacuum is approximately 186,000 miles per second or 300,000 kilometers per second, the same as the speed of light. When these waves pass through matter, they slow down slightly, according to their wavelength.
