B2 verb ニュートラル

amplitude

/ˈæm.plɪ.tjuːd/

Amplitude refers to the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It essentially describes the height or strength of a wave, such as sound or light, and can also denote breadth or range in a more general sense.

よく混同される語

amplitude vs frequency

Frequency is how often a wave repeats per second, while amplitude is the height or strength of each individual wave.

amplitude vs altitude

Altitude refers to vertical height above sea level, whereas amplitude refers to the extent of a vibration or wave.

使い方のコツ

While 'amplitude' is a technical term in physics and engineering to describe wave height, it can be used metaphorically in business or literature to describe the 'extent' or 'fullness' of a phenomenon.

⚠️

よくある間違い

Learners often confuse amplitude with loudness. While higher amplitude usually results in a louder sound, amplitude is the physical measurement of the wave, not the subjective perception of sound.

📖

語源

From the Latin 'amplitudo,' meaning 'wide' or 'large,' derived from 'amplus.'

文法パターン

Can be used as an uncountable noun when referring to the general quality of breadth. Used as a countable noun when referring to specific mathematical or physical wave measurements (e.g., 'varying amplitudes').
