From the following properties of a wave, the one that is independent of the other three is its?
Correct answer: A. Amplitude
- A. Amplitude
- B. Frequency
- C. Wavelength
- D. Time period
Explanation
The amplitude of a wave represents its intensity or strength, and it does not depend on frequency, wavelength, or time period. For example, you can have a high-amplitude wave with a low frequency, long wavelength, and long time period, or you can have a low-amplitude wave with a high frequency, short wavelength, and short time period. The intensity of the wave can be adjusted independently of these other properties.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
