What unit is equivalent to one million cycles per second?

What unit is equivalent to one million cycles per second?

• A. Gigahertz (GHz)
• B. Terahertz (THz)
• C. Kilohertz (kHz)
• D. Megahertz (MHz)

Answer: (D)

One million cycles per second is defined as one megahertz (MHz). The concept of frequency in telecommunications and electronics is measured in hertz (Hz), where one hertz corresponds to one cycle per second. By extension, prefixes are used to denote multiples of hertz: - A kilohertz (kHz) represents one thousand cycles per second (1,000 Hz). - A megahertz (MHz) represents one million cycles per second (1,000,000 Hz). - A gigahertz (GHz) is one billion cycles per second (1,000,000,000 Hz). - A terahertz (THz) indicates one trillion cycles per second (1,000,000,000,000 Hz). Since one million equals the definition of a megahertz, this makes it the correct answer to the question.

One million cycles per second is defined as one megahertz (MHz). The concept of frequency in telecommunications and electronics is measured in hertz (Hz), where one hertz corresponds to one cycle per second. By extension, prefixes are used to denote multiples of hertz:

• A kilohertz (kHz) represents one thousand cycles per second (1,000 Hz).

• A megahertz (MHz) represents one million cycles per second (1,000,000 Hz).

• A gigahertz (GHz) is one billion cycles per second (1,000,000,000 Hz).

• A terahertz (THz) indicates one trillion cycles per second (1,000,000,000,000 Hz).

Since one million equals the definition of a megahertz, this makes it the correct answer to the question.
