What is the relationship between frequency and wavelength?

• A. They are directly related; as one increases, the other increases
• B. They are inversely related; as one increases, the other decreases
• C. They are independent of each other
• D. They are equal in measurement

Answer: (B)

The relationship between frequency and wavelength is one of inverse proportionality, meaning that as the frequency of a wave increases, the wavelength decreases, and vice versa. This relationship is defined by the equation: \[ v = f \times \lambda \] where \( v \) is the velocity of the wave, \( f \) is the frequency, and \( \lambda \) is the wavelength. In a vacuum, the speed of light is constant; thus, if the frequency increases, the wavelength must decrease in order to keep the product of frequency and wavelength (which equals the wave speed) constant. Conversely, if the wavelength increases, the frequency must decrease. This inverse relationship is crucial in various fields, including telecommunications, optics, and acoustics, as it helps in understanding wave behaviors and properties. The other options do not accurately describe the relationship. The idea that they are directly related does not hold true, as both cannot increase together without affecting the wave speed. Claiming they are independent ignores the definitive mathematical relationship that connects them. Lastly, stating that they are equal in measurement is incorrect since frequency and wavelength are measured in different units (frequency in Hertz and wavelength in meters). This misunderstanding would lead to incorrect calculations or interpretations in practical applications
