wavelength. In the context of light waves, brightness is determined by amplitude while hue is determined by the wavelength of the light wave. Changes in wavelength correspond to different colors in the visible spectrum, just like changes in amplitude affect brightness.
Low frequency waves have a very long wavelength. Radio waves are the waves with the lowest frequency, also known as electromagnetic radiation. +++ Muddled, because the question does not state in which context. The electromagnetic spectrum ranges from very low frequency radio, via infra-red (which is heat), visible light, ultraviolet light and X-rays, to gamma radiation. Wavelength is a function of frequency and speed through the medium carrying the signal (including in-vacuo for electromagnetic): Wavelength = Speed / Frequency. (Speed not velocity, because the latter is a vector.)
The energy of a wave is determined by its amplitude, which is the height of the wave from its equilibrium position. A wave with a higher amplitude will carry more energy. Additionally, the frequency of the wave, which is the number of complete oscillations per second, also affects the energy of the wave.
Key words for light include illumination, brightness, photons, and electromagnetic spectrum. Key words for sound include vibration, frequency, pitch, and amplitude.
Pitch refers to the frequency of a sound wave, while volume refers to the amplitude. To change pitch, adjust the frequency of the sound wave, such as by tightening vocal cords for higher pitch or loosening for lower pitch. To change volume, adjust the amplitude of the sound wave, such as by speaking louder or softer.
Loudness, pitch and timbre are approximately the correlates of signal amplitude, frequency and frequency spectrum, respectively.
It is not meaningful to talk about "amplitude of the visible light spectrum". One might think that more intense light would mean greater amplitude of the light wave, but it just means more photons. "Visible light" is made up of photons. A single photon has a certain quantifiable energy, and that energy is discussed in terms of frequency or wavelength. A photon with low frequency (towards the red end of the visible light spectrum, for instance) is less energetic than a photon with high frequency (towards the blue end and beyond). For all intents and purposes, the amplitude of a photon wave-packet could be said to be of "unit amplitude", the amplitude of light.
Loudness, pitch and timbre are approximately the correlates of signal amplitude, frequency and frequency spectrum, respectively.
an oscilloscope give amplitude v/s time display of a wave, whereas the spectrum analyzer gives amplitude v/s frequency display. the oscilloscope gives distribution of energy in wave with respect to time whereas the spectrum analyzer displays frequency components of a wave and their amplitudes.
Volume (loudness), pitch and timbre are approximately the correlates of signal amplitude, frequency and frequency spectrum, respectively.

A periodic signal with a bandwidth of 70khz and highest frequency 200khz all frequencies have amplitude of 110v draw the spectrum in frequency domain utilizing Microsoft Excel charting facility? Answer this question…
Amplitude is typically measured using a signal processing tool known as an oscilloscope. An oscilloscope visually represents the magnitude of a signal over time, allowing users to measure the amplitude of a waveform accurately. Additionally, digital multimeters and spectrum analyzers can also be used to measure amplitude in electrical signals.
