❓Frequently Asked Questions
What is frequency?
Frequency is the number of complete oscillations or cycles that occur in one second. It's measured in Hertz (Hz), where 1 Hz equals one cycle per second. Frequency describes how often a repeating event happens.
What is the relationship between frequency and period?
Frequency and period are inversely related: f = 1/T. If period increases, frequency decreases and vice versa. For example, if a wave has a period of 0.5 seconds, its frequency is 2 Hz.
What are common frequency units?
Hz (Hertz) = 1 cycle/second; kHz (kilohertz) = 1,000 Hz; MHz (megahertz) = 1,000,000 Hz; GHz (gigahertz) = 1,000,000,000 Hz. Radio stations use MHz, computer processors use GHz.
How is frequency used in everyday life?
Frequency is everywhere: radio stations (88-108 MHz FM), WiFi (2.4 or 5 GHz), electrical outlets (50-60 Hz), sound waves (20-20,000 Hz audible range), and microwave ovens (2.45 GHz).
Can frequency be negative?
No, frequency is always positive because it represents a count of cycles per unit time. Negative values have no physical meaning in the context of frequency measurements.
What's the difference between frequency and wavelength?
Frequency is how many cycles occur per second, while wavelength is the physical distance between successive peaks. They're inversely related: higher frequency means shorter wavelength (λ = v/f).
