Question

1 GHz frequency corresponds to which region of the electromagnetic spectrum?

• A. Ultraviolet rays
• B. Radio waves
• C. Visible rays
• D. X-rays

Hint:

1 GHz frequency lies in the radio wave region of the electromagnetic spectrum, which is used for various communication applications.

Answer 1

The Correct Option is B

The frequency of electromagnetic waves determines their position in the electromagnetic spectrum. The different regions of the spectrum are associated with different ranges of frequency and wavelength.
1 GHz (gigahertz) corresponds to a frequency of \( 10^9 \) Hz. This frequency is within the range of radio waves in the electromagnetic spectrum, which typically spans from 3 kHz to 300 GHz.
Radio waves are used for communication purposes, including television and radio broadcasting. Frequencies around 1 GHz are commonly used in modern communication technologies.
Hence, the correct answer is option (B) Radio waves.
