Question

Which real-world measurable property of waves corresponds to the "A" value in the equation relating frequency and wavelength, often expressed as c = fλ, where c represents the speed of light, f is the frequency, and λ is the wavelength?

A) Amplitude
B) Phase
C) Velocity
D) Polarization

Answer 1

The 'A' value in the wave equation c = fλ, where c is the speed of light, is actually λ, and it stands for the wavelength, which correlates with wave velocity, represented as Option C) Velocity.

Step-by-step explanation:

The real-world measurable property of waves that corresponds to the 'A' value in the equation c = fλ, where c represents the speed of light, f is the frequency, and λ is the wavelength, is Option C) Velocity.

In this context, 'A' is often misattributed in the question but actually corresponds to λ, the lowercase Greek letter lambda, which represents wavelength. It is important to understand that amplitude correlates with the intensity of the wave (brightness for light waves and loudness for sound waves), not velocity. The speed of a wave, which in the case of light is a constant (approximately 299,792,458 meters per second in a vacuum), is the product of its frequency and wavelength, as shown in the formula c = λν.
