1. What is the Frequency Formula?

The frequency formula calculates the number of wave cycles per second based on the wave's velocity and wavelength. It's a fundamental equation in physics, particularly in wave mechanics and electromagnetic theory.

2. How Does the Calculator Work?

The calculator uses the frequency formula:

Where:

• \( f \) — Frequency (Hz)
• \( v \) — Velocity (m/s)
• \( \lambda \) — Wavelength (m)

Explanation: This formula shows the inverse relationship between frequency and wavelength - as wavelength increases, frequency decreases, and vice versa.

3. Importance of Frequency Calculation

Details: Frequency calculation is essential in various fields including telecommunications, audio engineering, optics, and radio astronomy. It helps determine wave properties and behavior in different media.

4. Using the Calculator

Tips: Enter velocity in meters per second (m/s) and wavelength in meters (m). Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the standard unit for frequency?
A: The standard unit for frequency is Hertz (Hz), which represents cycles per second.

Q2: How does medium affect wave velocity?
A: Wave velocity changes depending on the medium. For example, sound travels faster in water than in air, while light travels slower in water than in vacuum.

Q3: What's the relationship between frequency and energy?
A: For electromagnetic waves, higher frequency corresponds to higher energy according to the formula E = hf, where h is Planck's constant.

Q4: Can this formula be used for all types of waves?
A: Yes, this formula applies to all wave types including sound, light, and water waves, as long as you know the velocity and wavelength.

Q5: What if the velocity is the speed of light?
A: For electromagnetic waves in vacuum, velocity is constant at approximately 3×10⁸ m/s, so the formula simplifies to f = c/λ.
