In electromagnetic waves, frequency is inversely proportional to
A. Amplitude.
B. Wave speed.
C. Wavelength.
D. ReflectioN.
Is the answer C?
Thank you
c = f*w
So as f goes up, w goes down.
Yes, c is the correct answer.
To determine the correct answer, let's consider the relationship between frequency and the other options:
A. Amplitude: The amplitude of an electromagnetic wave represents the intensity or strength of the wave, while frequency determines the number of complete cycles of the wave that occur per second. Therefore, frequency and amplitude are independent of each other.
B. Wave speed: The speed of an electromagnetic wave is constant in a given medium, such as the speed of light in a vacuum. Frequency and wave speed are also independent of each other.
C. Wavelength: The wavelength of an electromagnetic wave represents the distance between two consecutive peaks or troughs of the wave. Frequency and wavelength are inversely related. As the frequency increases, the wavelength decreases, and vice versa.
D. Reflection: Reflection is a phenomenon that occurs when an electromagnetic wave encounters an interface and changes direction. Reflection is not directly related to frequency.
Based on the above explanations, the correct answer is indeed C. Frequency is inversely proportional to the wavelength of an electromagnetic wave.
